Garmin Striker 7dv GPS Fishfinder with GT20-TM Transducer
Pickup available at Mercury Yacht Harbour
Usually ready in 2-4 days
Description
The STRIKER 7dv combines Garmin CHIRP traditional sonar with CHIRP ClearVu down imaging on a large, clear 7-inch WVGA display, so fish arches and underwater structure are easy to read at a glance. A built-in, high-sensitivity GPS lets you mark and return to hot spots, slipways and docks and keep an eye on your speed over ground.
As a fishfinder rather than a chartplotter it carries no preloaded charts, but waypoints and routes can be shared with other STRIKER and echoMAP units. The supplied GT20-TM transducer ships with transom and trolling-motor mounting hardware and a temperature sensor, and the rugged IPX7 housing suits open-water and ice fishing.
