One of the only things better than sliding across the water on your kayak is fishing from it. Many folks who fish from kayaks find fish finders beneficial, but if you’re planning on this type of angling adventure there’re a few things you’ll want to keep in mind when you select your finder.

Type of Fish Finder

There’s no need to worry too much, though, there’s basically three types of finders which are best suited for kayak fishing. Once you’ve decided on which type you’re going for, there’s sure to be a number of options.


  • Smart Fish Finders: These are relatively new to the marketplace, and these will connect easily with your phone and often offer surprising resolutions and features. Most won’t necessarily need a cell tower connection either, instead, you’ll be able to access them using a Bluetooth signal. The biggest disadvantage of these for kayak fishing is pretty obvious, however, that you’ll need to have your phone over the water. If you’re risk-averse where you’re device is concerned but still want to utilize one of these high-tech gadgets, you’ll probably want to look into measures to keep your smartphone safe and dry, however.
  • Portable Finders: The go-to of pier and rock fishermen everywhere, these devices are often pretty low tech with a lot still using old LCD screens. They tend not to be quite as accurate, and you might find yourself having to sweep the transponder more often than you’d like, but they’re generally cheap and fairly reliable. They’re usually battery operated, which makes for a convenient and accessible experience.
  • Mounted Units: Several smaller transducer units will mount on your kayak quite easily and give you the same capabilities as someone piloting a larger vessel. If you pick carefully you’ll have all of the functions and none of the drawbacks, but for most of them, you’ll also need to carry a power system within your kayak.


Other Considerations

For most kayak fishing, you’ll find that ridiculous power and frequency used for people who fish in deep lakes or open oceans isn’t necessary. You’ll also want to find something with a smaller screen, so you won’t be excessively cramped up in your already tight quarters.

Something with 3-D imaging may also be ideal if you prefer to fish specific structures, and GPS is also useful for this type of fishing. The 3-D imaging will let you get a better look at where you’re dropping your line, and GPS can help keep you on target.

You’ll find a lot of utility no matter which unit you eventually settle on, though, but it’s aways best to make sure your first purchase is a great one. If you’re looking to increase your fishing pleasure in a kayak, read on as we’ve reviewed some great finders to use in conjunction with your boat.
