Garmin Echo 551dv Fish FinderEDITOR’S PICK – Garmin Echo 551dv

Kayak fishing is a sport that is increasing rapidly in popularity, and fisherman are outfitting their kayaks with top of the line equipment to get on the fish. Having a good fish finder is integral to success in a kayak today, as they will help you locate the fish so you can catch them. Learn more about how to choose a fish finder by clicking here, otherwise read on to learn more about the best fish finder for a kayak.

Garmin Echo 551dv

Garmin Echo 551dv Fish Finder best for a kayak

.

$$$

The Garmin Echo 551dv is about perfect for kayak fishing. It’s 5 inch screen is not too big to get in the way, but still plenty for easy visibility. As far as features go, Garmin has a system called Smooth Scaling that allows the fish finder to easily transition between shallow and deep water without you having to let go of your paddle and pressing buttons. It’s also easy to snap in and out, so you can take it with you, and the tilt and swivel base allows you to view it from anywhere. The interface is very simple and easy to use, saving you time from trying to find various options in the menu.

The 551dv comes with DownVu, which is Garmin’s down imaging that gives clear pictures of the bottom. This makes it easier to find structure to fish. The frequencies that this fish finder uses are 77 and 200, making it great for both deep water and for shallow water imaging. Another feature is the sonar rewind feature, which allows you to rewind back through images you have viewed to see if you missed anything. The max depth is 2,300 feet, making it a great choice for those fishing deep freshwater lakes. The transducer can be mounted on either the transom or trolling motor.

The only thing this fish finder doesn’t have is GPS, so if you are looking for something to download maps on or see where you are at in relation to structure, move on to the next fish finder.

Humminbird Helix 5 with Down Imaging and GPS

Humminbird Helix 5 DI GPS Fish Finder

.

$$$

The Humminbird Helix 5 is another great option for kayak fishing. This fish finder is ideal for those kayak fisherman who are fishing shallow water, as the max depth is only 600 feet, but it is very detailed where it is designed to be used. The base for this is a gimbal system, so it does swivel on that as well. The display size is 5 inches.

Like the 551dv, this does have Down Imaging to get clear pictures of the bottom under you. It reads in three different frequencies – 200, 455, and 800, which are all great detail frequencies. The images on this should be very clear. Humminbird also has a feature called DualBeam, which allows two frequencies to combine to get great detail as well as a wide search area – normally, you would get one or the other.

The GPS allows you to add waypoints or track your route so you can come back and fish the same area later. It comes stock with their UniMaps software, so you can use it straight out of the box or upgrade to another software like Navionics. This also will track your speed in case you are trolling.

All in all, if you are a shallow water kayak fisher and want to track your journey, this fish finder is the way to go.

Garmin Striker 4DV

$$

For the kayak fisherman on a budget, the Garmin 4DV is a great option. With a swiveling base and small size, this will fit well on your kayak. It can even be used for ice fishing with a built in flasher! The screen size is only 3.5″ diagonally, so if you are looking to conserve space and money, this fish finder is your best option.

The frequencies are many with this fish finder, and that gives you a lot of options. You can fish deep, up to 1,750 feet freshwater or 830 feet saltwater, or fish shallow with their higher frequencies for better detail. All the options give you a great fish finder for finding fish and structure, using the lower frequencies, then dialing in on exactly what the bottom looks like with their DownVu technology. Using 800 kHz, the images should basically be a picture of the bottom.

The GPS on this is very basic, as it doesn’t allow you to use a lake map but rather just tracks your speed, journey, and waypoints. This means you can come back to the same spot, but it won’t show you any maps of the lakes you fish. Marking waypoints will allow you find hotspots and return later.

The built in flasher means this could be a year round investment for kayak fishing in the summer and ice fishing in the winter, and at this price, it’s a bargain. The only difference between this fish finder and much more expensive ones is the screen size.

Conclusion

All these fish finders are great options if you are a serious kayak fisherman. It depends on which features you want at which budget, so choose the one that you believe will fit your fishing style and budget and get the best fish finder for a kayak. Good luck choosing and good luck fishing!

 

How to Choose a Fish Finder

.
Humminbird Helix 5 SI/GPS Fish Finder, a top fish finder

How to Choose a Fish Finder

Choosing a fish finder isn’t easy. There are so many numbers, specs, options, and more that can make the process seem a lot more complicated than it actually is. These tools can make fishing a lot simpler and allow you to make it more of a science to increase your catch rate consistently, but first you have to choose the correct one for your style. There are a few numbers and options to make note of. These are frequency, depth, cone angle, down imaging, side imaging, GPS, and sensors. If you want, click here to look at the best shallow water fish finders and click here to look at the best fish finders under 300 dollars after reading this.

Frequency

Frequency is one of the first items to take a look at. The frequency is measured in kHz, or kilohertz. Basically, the higher the frequency, the better the details on screen showing fish, structure, and more. However, higher frequencies often do not read back in very deep water, so they are normally used inland on shallow lakes under a few hundred feet. Frequencies can range from as little as 15 kHz to 800 kHz with down imaging.

The most standard frequency found on lakes inland is 200 kHz. This is good enough to get as much detail as you need, while still able to reach down to good depths. If you really fish only lakes under 150 feet, you can use imaging frequencies of up to 800 kHz, which is good enough to get you a still picture of the bottom. Most often, this high frequency is used through what companies call down imaging or side imaging, which can give you a clear picture of the bottom around you.

As frequencies get up around 400 to 800, the prices start getting high, but this type of clarity can really help you hone in on structure and bait schools. For most anglers, 200 kHz is outstanding and does the job of showing them the generic structure. If you fish deep lakes like the Great Lakes, you will want to look into something with a lower frequency like 83 or 55 to reach the depths and show you the entire water column.

The rule of thumb with frequency is the higher you get, the more clear of a picture you will get but the lower the depth, while the lower you get, the less clear the picture but the greater the depth.

Depth

Depth is an important consideration that ties in hand in hand with frequency. A good rule is to get a fish finder that can fish deeper than the deepest lake you fish, but not too much, otherwise you will compromise frequency. You want the highest detail you can get for the depth you fish. You can purchase fish finders that are thousands of dollars that will give you both depth and clarity, but these are beyond most people’s budgets.

Cone Angle

Frequencies are emitted in a cone like shape. The transducer that sends the signal down is the narrow end, while the frequencies get wider the further down they go. Manufacturers measure the angle of this cone to tell you how much ground your fish finder is showing you at certain depths. A 45° angle shows you the same ground diameter as depth you are fishing. For example, if you are fishing 30 feet of water, a 45° cone angle will show you a circle 30 feet in diameter around your boat. A 60° angle will give you slightly more (1.15 times depth), while a 20° will give you about one-third the depth you are fishing. For example, at thirty feet, you will get a 10 foot circle on the bottom with a 20° angle while you would probably get close to a 35 foot circle with the 60° angle.

Generally, as the angles get bigger and bigger, the frequency must go down and therefore the sensitivity gets lower. At 60°, you will frequently find fish finders that will measure it at 83 kHz, while at 20°, you will find fish finders that measure it at 200 kHz. Many fish finders are able to measure both of these through what manufacturers called dual-beam transmission, which you can switch between.

The purpose of this is to allow you to use the lower frequency but wider cone angle to search for structure and schools of fish, while you would use the higher frequency but smaller cone angle to narrow in on the fish and the structure itself.

The exception to this is side imaging. New technology has allowed some manufacturers to send high frequencies off at angles like 80° to give you a clear picture of what is to the sides of your boat. These aren’t effective at great depths, but work very well for shallower water. This will be discussed further down.

Down Imaging

.
Click this picture to view this Down Imaging Fish Finder

Down imaging, shown above, is basically crystal clear images that are created by sending high frequencies down. These frequencies generally start around 400 and go up to around 800, and will give you a very clear idea of what is on the bottom, as you can see. These aren’t very effective at great depths, but work up to a couple hundred feet. If you fish for fish that often sit around structure, these are the way to go. They may not work quite as well as sonar at identifying fish because they make everything closer to it’s actual size in proportions to the bottom. However, many species of fish like walleye, bass, and crappie choose to hang close to structure and down imaging is what will help you find it.

Side Imaging

.
Click this picture to view this Side Imaging Fish Finder

Side imaging is shown above. These are high frequency waves that are sent out to the side at extreme angles, normally close to 85°. They give you a very clear image of what is to the side, and normally you can see great distances off to the side with these. These are even better than down imaging at locating structure, as you would merely have to make a few passes over an area you know to contain structure to pinpoint exactly where you want to fish. These are extremely handy for shallow water fisherman, but don’t do much past 150 feet.

GPS

.
Click this picture to view this Fish Finder with GPS

If you want to track where you have been, locate points, dropoffs, and more, and mark waypoints, you need to purchase a fish finder with a GPS. Most of these are able to be integrated with maps of lakes, so you can cruise from spot to spot looking for structure and fish. You can also track your journey so you don’t get lost and so you can follow the same path next time, or just mark waypoints of where you caught fish to come back again as well.

Sensors

Fish finders can come with many different sensors that can help you make fishing even more of a science if you keep a careful journal. These are water temperature, boat speed, time, GPS coordinates, and more. Look carefully at your options and normally you will have to pay a little more for some of these options, but they are worth having so you can start noticing patterns.

Conclusion

Fish finders seem pretty complex when you first start looking for one, but once you know exactly what you are looking for, they become a lot easier to understand. Click here to look at the best shallow water fish finders and click here to look at the best fish finders under 300 dollars.

If you fish a lot of shallow water, you know it can be a struggle to get a fish finder that reads out far enough to be worth anything. Not all fish finders are created equal, and if you choose the correct one, it can make shallow water fishing a whole lot easier. Here we will discuss three of the best options on the market today for shallow water at different price points. You can also read more about how to choose a fish finder by clicking here.

Humminbird Helix 5 with Side Imaging and GPS Fish Finder

$$$$

The most expensive in our test, the Humminbird Helix 5 SI and GPS fish finder is definitely the top dog here as well. This fish finder was practically built for shallow water fisherman, with side imaging to show you images in a cone 85° away from your boat to each side, at 455 kHz to give you a clear picture as well! This gives you so much range when you are scouting for bait schools or structure it’s ridiculous! This side imaging is good to depths of 100 feet, while if you just use the standard sonar you can reach down to 1,500 feet. With the standard sonar, you have the options of using either 83 kHz for deep water or 200 kHz for better images in shallower water. The screen size on this fish finder is 5″ diagonally.

The GPS this comes with is preloaded with Humminbird’s UniMaps system, but you also have the option of using Navionics with it if you purchase it separately. If you have a microSD card, you can also save waypoints or maps from this fish finder as well so you can visit the same spot next time.

All in all, this fish finder has the capabilities that many more expensive fish finders have at a great price. The side imaging will open the water up for you in shallow water, and I would bet that you will notice an increase in your catch when you learn to use it effectively.

Garmin Echo 551dv Fish Finder

The Garmin Echo 551dv is a solid fish finder at this price, as they took GPS out and added some other features that make it a great option for many. It is highly portable and the transducer can be mounted to a trolling motor. Garmin has a system called the Smooth Scaling system that transitions smoothly and quickly from shallow water to deep water without any extra work, really giving you a hand if you are fishing dropoffs. The display size on this fish finder is 5″ diagonally as well.

As far as actually seeing the fish, this does have pretty solid sensitivity with the ability to read at 83 kHz at deep depths and 200 kHz for clear images at shallow depths. As you can see above, their DownVu technology creates some very clear images that make finding structure and identifying fish a lot easier. The maximum depth on this fish finder is 2,300 feet if you ever need to go deep. You can also rewind through your sonar if you think you missed something.

One great thing about this fish finder is how simple it is to use. The interfaces on the screen are very straightforward and simple, so it should be quick to learn. If GPS isn’t important to you but finding structure and fish is, this is the fish finder for you.

RayMarine Dragonfly 4 Pro Fish Finder

Raymarine Dragonfly 4 Pro Fish Finder

.

$$

The Raymarine Dragonfly 4 Pro is the cheapest of all these options, but it certainly doesn’t give up quality. With a beautiful sharp color display that is optically bonded, this screen should never fog up or allow moisture inside. The screen measures 4.3″ diagonally. This fish finder reads in three frequencies: 50, 83, and 200, with 200 being the most sensitive for the shallow water fishing you are doing. This is what produces their down imaging pictures, which is the clear picture of the bottom you can see in the picture above. The 200 kHz also reads at a 25° cone, which will show you some good bottom structure while giving you some outstanding pictures. The depth only goes to 600 feet, which shouldn’t be a problem if you are fishing shallow water only.

This fish finder comes stock with a GPS system equipped with C-Map Essentials, but it can be upgraded to several different types of maps. You can insert a memory card in order to save your route or waypoints to come back and fish them later.

The Raymarine 4 Pro also has another great feature – live wi-fi streaming of the fish finder so your buddies or you can watch it on your phone from anywhere on the boat. No more clustering around the fish finder!

For the price, this is another great fish finder for fishing shallow water.

Conclusion

All three fish finders discussed above will put you on the fish in shallow water while giving you the option of fishing deeper if necessary. Pick your budget and spend accordingly! Good luck and good fishing!

Part of the all-new Striker series from Garmin, the 5DV is a quality fish finder that can be used year round. The Striker 5DV has a 5″ display screen, which is measured diagonally. This display screen can be split into three sections: standard fish finding mode, GPS mode, and down imaging mode, which give you the crystal clear side image of the bottom, showing trees, rocks, and other structure in clear detail.

With the GPS mode, you can mark exactly where you catch fish and return, as well as control your speed as it does monitor that as well. However, it is noteworthy that this fish finder is not compatible with mapping, so the GPS is basically there to show you where you have gone and to save your hotspot marks. The 5DV also has some extraordinary depth capabilities, marking down to 2,300 feet of freshwater and 1,100 of saltwater! That’s right, this fish finder is also fully functional on saltwater, at some great depths to boot.

This fish finder is extremely portable, and you can actually purchase a kit to mount it anywhere you want very quickly. This is important for kayak, canoe, and ice fisherman who are constantly on the move. Speaking of ice fisherman, this fish finder is fascinating as it does have a flasher as well, so it is capable of being used for that. It functions the same way that many state-of-the-art flashers would, allowing you to see the hardness of the bottom as well as mark your lure and obviously fish as well.

The Striker may be the most expensive out of these 5, but if you are looking for a fish finder that you can use year round, hardwater and open water, this is the way to go. The one knock is the lack of mapping capability. If this is important to you as you like to see the bottom on a map, read on to our next fish finder.

The Raymarine DragonFly-4 Pro is a beautiful fish finder, and it functions wonderfully as well. The display screen size is 4.3″ diagonally, which can also be split to show standard sonar, down imaging, and GPS. This system will also show your speed, depth, and water temperature. With the GPS, you can mark your hotspots, and you can also take screenshots of underwater structure!

One very neat thing about this fish finder is that it is compatible with your phone or tablet through use of an app. This means no moving the fish finder around the boat with you – you can watch your phone from anywhere with it. Fishing partners on the boat could also watch it on theirs as well, so no more crowding around the fish finder! With this app, you can also rewind and look back over the route you covered to see if you missed anything or to see exactly where the piece of structure was you landed the wall-mounter off of.

The Dragonfly-4 Pro comes stock with many maps so you could fish with it right out of the box. The maps it comes stock with are C-Map Essentials, but it is also compatible with either Navionics or Raymarine Lighthouse maps if you prefer either of those. However, they would be a separate purchase.

All in all, the Dragonfly-4 Pro is about the best bang for your buck you’ll find – beautiful down imaging to clearly see the structure, effective sonar, and a good GPS system all wrapped into one. If you have fishing buddies rubbing shoulders to watch the fish finder, this may be the one to buy! Have them download the app on their phones and fish on in peace.

From one of the big names in fish finders, we have the Humminbird Helix 5. This is one of their more basic fish finders, and actually it doesn’t have the option of tracking by GPS or mapping. It does have a 5″ diagonally measured display screen that can be split to show both down imaging and traditional sonar, as well as water temperature.

The depth reading on this fish finder can reach up to 600 feet. One of the more plain fish finders that Humminbird offers, this one can still be updated or upgraded through their website for some small upgrades they offer to enhance performance. For the price, you are getting a solid fish finder that will show you the bottom in great detail through down imaging, as well as find the fish, from a great name brand in fishing.

Lowrance Mark-4 HDI Fish Finder

Another big name in fishing, Lowrance has produced an outstanding fish finder here at a great price. The diagonal display size is 4.3″, and can be split to show down imaging, sonar, and a great GPS system so you know exactly where you are on the humps or dropoffs. They saved a bit of money by not having a full color display like the rest, but they put that money back in where it counts and where other companies didn’t.

This fish finder does come stock with about 3,000 lakes around the US, but you can also purchase map upgrades through Navionics, Lake Insight, HotMaps, and Jeppesen. You can also create your own lake map using their sonar, so if water levels fluctuate or if stock maps seem to be missing data, you can create maps to save for the future. This fish finder also allows you to plot your route and mark hotspots to return to if you want.

You can also track back along the route you recorded to see if you missed any structure or to mark a spot to fish harder next time. This can come in very handy for analysis back at the cabin.

As you can see, the Lowrance Mark-4 HDI looks basic in it’s plain greyscale, but it is really anything but basic in its performance. At a great price, this is an outstanding buy from Lowrance.
