Campers will often pitch their tents or park their RVs near a lake or river so they can go fishing. Casting out in the afternoon and enjoying the catch at an evening barbecue are some of the simple joys of camping. But some days there’s no catch, and it’s canned beans for dinner — thankfully, technology can intervene and make that a rare occurrence.

With a fishfinder, such as the Deeper Sonar PRO+ 2, you increase your chances of a fish supper tenfold. The Pro+ 2 is perfect for shore or boat fishing. And if your camping trip is taking you a bit farther north, it’s ideal for ice fishing, too.

With this game-changing gadget, you can create bathymetric maps using the built-in GPS. You simply cast the device out up to 330 feet, and it will scan the depths below, down to 260 feet. The GPS then relays information on depth, the shape and texture of the lake or river bed, any vegetation down there, and even fish activity.

With this information, you can identify specific species and where they might be hanging out. It will also give you valuable insights into tackle and bait selection, as well as which fishing techniques to utilize. There are other gadgets you might want for your next fishing trip, but a fishfinder is, without a doubt, the most fun.
