7. HawkEye FT1PXC Fishtrax Kayak Fish Finder

When looking for the best portable fish finder for kayaks, it’s difficult finding one that lives up to your expectations. Normally things like convenience, efficiency, and reliability come at a premium cost. However, the Hawkey FT1PXC Fishtrax Fish Finder has some great features at a reasonable price.

The Fishtrax Fish Finder features start with HD full-color and an adjustment of 100 levels. There’s bottom tracking with auto-zoom for an enhanced target view that works well in most water types. The Fishtrax also includes a Digital Flasher Portrayal for Ice-Mode fishing.

A little larger than a smaller size smartphone, the Fishtrax by Hawkeye is small enough to fit in your hand. Four AAA batteries power the Fishtrax, giving it a maximum 30 hours of fishing time. The AAA batteries eliminate the need for 12V marine batteries found on large fish finders.

Even though the FishTrax has a portable compact size, it’s packed with full-size fish finder features. All FishTrax models have full featured transducers, giving them the ability for transom mount, shore fishing or trolling. The separate transducer and added accessories make the FishTrax mountable to most platforms, and you have a maximum depth of 120-feet.

Two different frequencies for deep water and shallow water give the FishTrax a better-quality picture. The fish finder displays readings in shallow water of 1.5-feet to deep water of 240-feet. For kayak fishing, this is ample depth leeway. The only drawback is the FishTrax is not recommended for saltwater.

Like large fish finders, the FishTrax has adjustable SONAR sensitivities, with different presets.

8. Humminbird 410060-1 Fishin’ Buddy Max DI Fish Finder

Compact and light weight, the Humminbird Fishin’ Buddy makes the perfect finder for those anglers always on the move. The 4.22 x 2.72 x 5.76-inch size and 6.6-pound weight make this a best portable fish finder for kayaks.

Unfortunately, the Selective Fish ID does not have the greatest accuracy. Other targets like vegetation, debris, and other submerged items may show as fish icons. However, if you understand the raw sonar view, this is a great function on the Fishin’ Buddy fish finder.

Three alarms, depth alarm, fish alarm, and battery alarm, come standard on the 410060-1 Fishin’ Buddy Max. The fish alarm has three fish sizes, large, medium, and small, letting you choose one or all for alarm sound. When the battery voltage falls to less or equal to the menu setting the battery alarm sounds. With the depth alarm, it sounds when the depth falls to less or equal to its selected value.

The Fishin’ Buddy has two other functions included for accurate fish finding. The WhiteLine function highlights strongest sonar signals in white for a distinctive picture of the bottom contour. The Structure ID shows the weak signals and light-colored pixels while strong signals come in darker.
