Garmin STRIKER™ 4dv

Experience the Clarity of CHIRP
STRIKER 4dv includes a Garmin CHIRP (77/200 kHz) transducer, which provides a visibly higher level of clarity and detail for fish and structure than traditional 77/200 kHz transducers.

Instead of sending just 1 single frequency, CHIRP sends a continuous sweep of frequencies, ranging from low to high, then interprets them individually upon their return. Since the frequencies provide a wider range of information, CHIRP sonar technology can create crisper fish arches with greater target separation.

You also can upgrade to high-performance Garmin CHIRP technology, which provides crystal-clear sonar images with even more remarkable target separation and resolution from shallow to deeper depths. For better fishing, bottom contours are more visible, even at higher speeds, and signal noise can be suppressed at greater depths to provide a more timely interpretation of what’s below.

Clearest Scanning Sonar on the Water

Garmin DownVü scanning sonar gives you a nearly photographic image of what passes 750 feet below your boat. You clearly see structure, submerged objects and fish. Traditional Garmin CHIRP sonar and CHIRP DownVü scanning sonar are combined into 1 transducer.

Mark Spots with High-sensitivity GPS
Unlike regular fishfinders, STRIKER fishfinders have built-in, high-sensitivity GPS to locate your current position quickly and precisely, then maintain your GPS location anywhere you go on the lake. More importantly, they allow you to mark spots where the fish are biting so you can return to them again in the future. You also can mark docks, boat ramps and other locations on the lake. Just follow the path created on your screen to return to them whenever you wish.

Navigate Easily with Waypoint Map

Since the STRIKER fishfinder series includes high-sensitivity GPS, you can see your position in relation to waypoints you have marked. Use the waypoint map to easily view, mark and navigate to locations such as brush piles, stumps and docks. It’s also a great tool for finding your way back to the boat ramp.

Check Your Speed on Screen

You can quickly and easily see your boat’s speed on the screen of your STRIKER fishfinder. It’s a great tool to make sure you are trolling at the right speed for the lure you’re using and for a particular fish species. It’s also a good way to tell if you are going the right speed in wake-controlled areas.

Fish Vertically with Built-in Flasher
STRIKER provides you with both a fishfinder and flasher all in 1 unit. Anytime you are stationary fishing, such as ice fishing or jigging for crappie, the built-in flasher will show you the bottom, whether it is solid or muddy, your jig or weighted bait, and the depth of fish as they swim into the sonar beam. You can even watch how high your jig is being lifted and dropped and whether fish move toward or away from it.

Take Your Fishfinder Anywhere

A portable kit is available to protect and carry your STRIKER fishfinder with GPS, so it’s perfect for kayak, canoe or ice fishing. It includes a sealed, rechargeable battery with charger, built-in transducer cable management and storage and suction cup transducer mount and float.
