Top Fish Finders Features To Consider

  • Screen Size – Larger screens with high definition graphics are going to provide you with more detailed information.  These large fish finders are great for larger boats and watercraft with ample space and mounting surfaces.  But if you are fishing from a kayak, canoe, or even a float tube, a smaller compact unit with a smaller screen might be a better option.
  • GPS – All of the technological advantages of GPS on dry land can also apply on the water.  When you find a hot fishing area, a fish finder equipped with GPS provides for plotting charts and keeping record of prior locations so you can easily return to your favorite spots.  Advanced models offer maps and depth charts which can be downloaded and viewed from the water.
  • Wireless Capable – Wifi connectivity offers the ability to share and stream your data by connecting to your smart phone or other cellular devices.  Wireless capabilities makes sharing locations and information with your friends and family super easy.
  • Portability – Some fish finders are designed to be permanently mounted and wired into your boat.  Other fish finders remain fairly portable so that moving your fish finder to another boat or into your house is a breeze.  Portable fish finders offer a lot of benefit if you have multiple watercraft and only want to buy a single fish finder.

If you’re on the hunt for a fish finder, hopefully, these reviews will point you in the right direction.
