Review on 🐟 Garmin Striker 7SV GPS Fishfinder: Chirp Traditional, ClearVu and SideVu Sonar Transducer, Quickdraw Contours Mapping Software (010-01874-00) by Riley Skeet

Too bad I didn't look at the reviews. GPS with contour map. apparently means no GPS maps. It's basic and the sonar is great, but the huge yellow screen with no map other than a trace of where you were threw me until I checked the reviews. What very upset. I just saw a chart in Amazon's product marketing and assumed the device was a combination chartplotter and sonar. Guilty. .but I still gave a low rating for false advertising. I would have sent it back but it was installed and past the 30 day return policy before I ran my boat.
