About Fishfinders

GPS Fish Finders & Depth

Fish finders from Defender include the most innovative electronics available today. Multifunctional displays show fish finders with GPS chart displays. Additional optional displays include depth finders and navigational charts.

Navigate your way to the fish

Commonly known on the docks as "plotters", fish finders with navigation features do more than get you to the fishing grounds and back. Fish finders with GPS track your bites on the chart enabling navigation back to the fishing hole of your dreams or back across a temperature change that is holding fish. Some say you can't catch yesterday's fish but with the right fish finder and nav system, you can try!

All you need right in one place

Multifunctional displays allow boaters to see their GPS, fish finder, navigational systems, and even radar in one unit. Check your application, current electronics, and any additional functions you may want to add in the future to determine the best multifunctional display for your boat.

Not your mama's fish finder

Omni directional, side scan, and 3-dimensional readings seemed like the future of fishing just a few years ago. Today fish finder science and technology have moved forward in leaps and bounds. Order the fish finder of your dreams today and stack the fish-catching cards in your favor!
