Garmin Quickdraw Contours

While you navigate the shores and depths of your current location, Quickdraw Contours bathymetric mapping software creates high-resolution depth maps of your current location, with no special knowledge required. STRIKER™ Vivid 4cv can now store up to 8,000 sq. km of area with 30 cm contours.

CHIRP ClearVü™ Transducer

STRIKER Vivid 4cv fishfinder features CHIRP ClearVü™ sonar, which provides a near-photographic view of what’s below your boat down to 750 feet (229 m). You’ll see structure, submerged objects and fish clearly. It also features a traditional Garmin CHIRP sonar for easy fish identification.

GPS receiver

The built-in, high-sensitivity GPS receiver finds and pinpoints your location anywhere in the water. GPS lets you mark waypoints at different locations, so if fish gather in one spot, you can mark it and return to the same spot on your next trip. You can also mark docks, boat ramps, and other areas of interest to you on the water. The GPS receiver also allows the STRIKER Vivid 4cv to display your boat speed on the screen, so you can be sure you’re moving at the right speed. This is a great tool to know if you’re fishing at the right speed for the bait you’re using and the type of fish you’re fishing for. This feature is also useful when fishing in areas where boat-generated waves are restricted.

Designed for you

The STRIKER Vivid 4cv fishfinder makes fishing a pleasure and is built to work in any environment. The color, sunlight-readable display gives you a clear view on sunny days. The larger display gives you a better view of what's happening below the boat. Intuitive controls make it easy to access any function you need, so you're ready for any challenge on the water.
