It's your post, so post it!
The Helix 5 Sonar G2 was the first kayak fish finder I bought, and I still use it on my Jackson Mayfly. If you have an Old Town or Ocean Kayak, mounting the transducer is easy, and the cable will pass right through the scupper. On a kayak like the Mayfly, you can DIY a mount or use the YakAttack SwitchBlade transducer arm.
The 5-inch screen is large enough to clearly see bottom contour and structure detail, but small enough that it is out of the way. You’ll navigate the menus and adjust settings using the keypad, which isn’t as fast as a touchscreen, but it’s less likely to fail on you.
The imaging is pretty basic, but you have to adjust your expectations when going to a budget fish finder. I use this unit just to know how deep the water is, find hard pieces of structure like rocks, and find drop-offs. I don’t rely on it for detecting anything subtle or reliably marking bait. But, for a lot of fishing, those basic functions are all I need.

Ric Burnley fishes for a variety of saltwater species in the waters near Virginia Beach. “I went a lot of years without a fish finder just because they were too much of a pain in the neck,” he said. “But fish finders have co*e a long way.” Burnley now rarely fishes without his Helix 7 mounted on his Ocean Kayak Trident 13. “I love the side-scan for speckled trout fishing,” he said. “You can see schools of speckled trout, find grass beds, and structure. It’s also almost essential for our spring big red drum fishing.”
To use his Helix 7 to find big drum, Burnley will paddle around looking for schools of bull reds on the side imaging. The side imaging shows what’s happening 125 feet on either side of the boat, and it allows anglers to quickly cover water. “You need to beco*e an expert on reading the side scan and what different marks represent. But when those drum show up on there, it’s very obvious,” he said. Burnley owns other fish finders with side scan, but he thinks the Humminbird’s contrast and detail is the best.
The Helix 7 doesn’t co*e with detailed charts, but they are good enough for navigation. You can upgrade the maps if you need detailed charts though. One feature Burnley often uses while searching for drum is the bread crumb feature so he can see where he’s covered and can backtrack to where he last saw fish. Burnley also noted that after several seasons of hard use his Helix 7 is still trouble-free.
If you want to build a tournament-ready fishing kayak, then you’ll be looking at premium accessories like a Torqeedo motor and LiveScope. Both will help you catch fish more efficiently and step foot on the podium. But, that advantage doesn’t co*e cheap or without some specialized rigging. Typically, a LiveScope transducer mounts on a boat’s trolling motor, and you can pan the sonar by turning the trolling motor. On a kayak, that’s not easily done. Most anglers using LiveScope or other live sonar will mount the transducer on a rotating arm. In addition to that specialized mount, you might also want to consider having two screens on your kayak—one for LiveScope and one for mapping and side/down imaging. The added electronics, of course, means more power and smarter cable management. But, if you’re willing to put in the time and effort to rig your kayak properly, you’ll have a fish-catching machine.

The best fishing kayaks are already heavy, so adding a battery will only add to that weight. To keep your kayak as light as possible, you can use a lithium battery, which is typically half the weight of cheaper lead-acid batteries. The best kayak fish finder battery I’ve used is the Dakota Lithium 12V 10Ah, which gives me plenty of power to run a fish finder all day. After I’m done fishing, I plug it into a charger, and it’s ready to go by the next morning. They are more expensive, around $100, but they’re good for 2,000 cycles and carry an 11-year warranty. For efficiency, longevity, and weight, I haven’t found anything that beats the Dakota Lithium batteries.
I’m not the handiest person, so when it co*es time to rig power, I hit the easy button and buy a Yak-Power Power Pack. You put your battery of choice into the box, attach the cables, and you’re ready to plug in your fish finder. At least that’s how it’s supposed to go, but of course, I needed to do some minor wiring to make it co*patible with my battery and fish finder. First, I changed out the battery clips that came installed in the battery box because they were too small for my Dakota Lithium battery. Then I spliced a SAE connector to my fish finder’s power cable. With those two easy modifications out of the way, the battery box was ready to use, and it fits nicely in the front hatch of my Old Town Bigwater PDL. Those two modifications take minutes and is way easier than trying to rig up a battery box with an on/off switch, USB plugs, and power plug.
You can spend a few hundred or a few thousand dollars on a fish finder. The model you choose will depend on your style of fishing. If you enjoy a technique like deep-water jigging for lake trout, a fish finder is a critical piece of gear and you’ll want to invest in a quality unit. But, if you spend most of your time fishing saltwater flats, a fish finder is less important and you can get by with a less expensive model. Aside from price range, you’ll also want to decide between different transducers, screen sizes, and also consider how easily the electronics will mount to your kayak.
There are three basic types of transducer you can choose from: down imaging, side imaging, and live sonar. Down imaging is the most basic type of transducer and is best for deep water fishing or anglers on a budget A side scan transducer is the most versatile because it will allow you to look at the water below you and the water on either side of you. The side-scan feature is excellent for quickly covering water and most units will cover 100 feet on either side of your kayak. Live sonar is the new craze in fish finders, and many of the best fish finders are now available with some type of live sonar transducer. Live sonar is highly effective, but it does create added challenges for mounting in a kayak and will require an adaptor.
I think a 7-inch or 5-inch display is perfect for a kayak. They’re large enough to see details, but co*pact enough that they don’t get in the way.
Kayak co*panies have smartly partnered with fish finder co*panies to make mounting a transducer and fish finder much easier. You might decide to choose a particular manufacturer because their units are most co*patible with your kayak. For example, Humminbird fish finders easily mount to Old Town and Ocean Kayaks. Lowrance units mount seamlessly with Hobie kayaks. But, you can mount any of the best kayak fish finders on any fishing kayak with some minor modifications or by using one of the aftermarket traducer arms.
Fish finders are powered by 12-volt batteries. The most co*mon sizes are 12V 7Ah and 12V 12Ah.
Any fish finder will work on a kayak, but some mount easier without drilling or modifications. For example, a Lowrance fish finder mounts easily to Hobie kayaks.
A general rule of thumb is that you can expect one hour of use per amp hour. So a 12V 7Ah will run a fish finder for about 7 hours.
For certain types of fishing, a fish finder improves success drastically, and it’s a handy tool for most types of fishing. So, embrace modern technology by choosing the best kayak fish finder for you.
