Lowrance Elite-4M Gold Chartplotter
This is the perfect marine GPS for anyone who already has a fishfinding sonar but just wants a gps.  My fishfinder is built-in to the dash and would have been a difficult chore to replace with a fishfinder/chartplotter combo.  So instead I was in the market for just a GPS that I could mount on my dash.  Lowrance makes some of the best products for anything boat related so when I found this version without sonar I knew this is what I wanted.  It was the right price as well and installation was a breeze other
