Garmin STRIKER 4

Product Codes: GARS4

The Garmin STRIKER 4 is a Fishfinder and also features GPS technology. The screen size is 3.5-inch with keypad control. There is an included Transducer and Sonar.

Using the GPS technology you can mark waypoints and navigate back to them. You will also be able to view your boats speed.

The included traditional transducer provides you with a view below your boat. Traditional sonar is best for finding fish below you boat. However if you want to identify structures below your boat (rocks, wrecks, etc.) then we recommend buying a Fishfinder with DownVu or SideVu instead.



Garmin STRIKER 4 has been discontinued. The replacement model is the Garmin STRIKER Plus 4cv.
