Fish Finders for Your Kayak, Canoe, or Jon Boat

News & Tips: Fish Finders for Your Kayak, Canoe, or Jon Boat...

Finding fish in extreme shallows is made a lot easier with a kayak, canoe or jon boat that can almost float in fresh dew, but what about those months when the fish are deep offshore? To be versatile year 'round, your paddle-craft or other flyweight boat needs some electronics to search out the depths.

The obvious problem is electrical power--most sonar/GPS units run on 12-volt power. No big, heavy 12-volt battery, no power. And who wants to lug along a battery that weighs almost as much as their boat?

Fortunately, several companies make portable depthfinders that can eliminate this issue--a lightweight built-in rechargeable battery keeps them running for hours.

Raymarine Fishfinder, GPS & Sonar

The Raymarine Dragonfly-4 Pro is a  fishfinder, chartplotter, and GPS navigation device featuring a 4.3" all-weather, anti-fog, high-definition LED-blacklit display for sharp color and wide angle viewing. This unit includes ball-and-socket swivel mount and has built-In Wi-Fi allows streaming straight to your smartphone.

raymarine sonarRaymarine has an interesting take on small boat sonar with their Wi-Fish Wi-Fi CHIRP DownVision Sonar, which is basically a "black box" plus transducer that links to cell phones and tablets--there's no separate monitor or screen. Of course, you'll want a waterproof housing for your device if you use it this way, but since all of us are so familiar with operating this technology today, the company says the learning curve is minimal.

Transducer Brackets

You may also need some sort of a transducer bracket to fit anything other than a jonboat transom, since flat spots on most canoes and kayaks are hard to find. The Scotty Kayak/SUP transducer arm mount and Sully transducer bracket, among others, make aftermarket mounts that can be fitted to most 'yaks and canoes.

Whichever sonar you choose and however you mount it, having underwater "eyes" on board will greatly increase your odds of angling success for anything from bass to catfish to crappies to walleyes on lakes across the country.
