Fish Finders

Ranging from simple fish finder only units, to those which also feature a basic GPS functionality. Those with basic GPS plotters feature a blank white basemap that allows you to plot your favourite marks. These units offer no option to add upgraded basemaps such as navionics, however the Striker Vivid series from Garmin offers QuickDraw Contours that maps out the seabed contours on a blank basemap as you travel over the ground. If you want the option to add highly detailed charts to your fish finder unit then view the models in the Fish Finder & Full GPS Chartplotter section further down the page.
