Why Do I Need A Kayak Depth Finder?

For the sake of not confusing anyone here, we’re going to stick to the term ‘Fish Finder’. Fish finders have a lot of great uses and they’re versatile, here’s why you want one:

  • You’ll have info on the depth and structures of the bottom = no more guess work.
  • Flat areas and structures become effortless to spot
  • You’ll know the water depths and also be able to spot dish and bait nearby


What You Want To Remember

There are a couple of things you want to keep in mind when you’re shopping for a fish finder, things like:

  • Power – essentially you need max wattage for max reading displays
  • Screen Resolution – the more pixels your screen has the more detail you’ll be able to see. Opt for no less than 240(v) x 160(h) pixels.
  • Transducers – this is what sends and receives sonar waves and signals into the water. In-hull or thru-hull transducer users: you’ll want to opt for plastic housing for metal hulls and fiberglass. Aluminum and steel hulls should ideally have stainless steel housings while bronze housing is best for fiberglass hulls.
  • Frequency – here you’ll be able to pick between dual, single and multiple frequencies.
  • Mounting space – this is kind of a deal breaker. Your kayak needs to have enough space to accommodate a 12V battery, cables rods and a screen to display the details on. Smaller kayaks are limited to 3.5 to 4 inch screens while the bigger kayaks can accommodate screens of up to 5 inches.

Great, we’ve covered the basics. Now it’s time to get to the real reason why you’re still reading.
