Garmin GPSMAP 8610 (NO TRANSDUCER PORT)

This Global map is a full networking unit making it compatible with all Livesonar options (Livescope) and sonar black boxes with a network port. It does not have a traditional sonar port like the XSV models. If you want to use a GT56 or other SI and 2D sonar transducers, please purchase the XSV model.
