Some fish finders that include GPS capability are the Humminbird 859ci and the Raymarine Dragonfly. The Humminbird 859ci has received higher customer reviews than the Raymarine Dragonfly and features a larger 7-inch screen compared to the Dragonfly's 5.7-inch screen with more powerful SONAR. Both devices feature dual-beam sonar capability.
When out in deep open waters, such as the ocean, it is recommended to use a chart plotter that features GPS and has fish finding capabilities over a fish finder with GPS capability for safety. A fish finder with GPS capability is better suited to smaller bodies of water such as ponds and lakes and is a good addition to a tournament equipment set up.
