Product DescriptionCHIRP Fishfinder with GPS and DownVü Scanning Sonar
• Easy-to-use 3.5" color fishfinder with built-in, high-sensitivity GPS and CHIRP DownVü scanning sonar
• Find fish; mark and return to hot spots, docks and ramps
• Includes Garmin GT20 transducer with CHIRP (77/200kHz and 300W) and CHIRP DownVü (455/800kHz and 300W)
Finding fish is easier than ever with Striker 4dv fishfinder. Mark and return to your hot spots, boat ramps, and docks. You also can share your favorite waypoints and routes with other Striker and echoMAP combos. Sonar history rewind allows you to scroll back through sonar images to mark waypoints you originally may have missed. Plus, it has a built-in flasher and displays speed data. Includes tilt/swivel mount plus transom and trolling motor mounting hardware and cable.
Experience the Clarity of CHIRP
Striker 4dv includes a Garmin CHIRP 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.
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. Garmin CHIRP 77/200kHz sonar and CHIRP DownVü scanning sonar are combined into one 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 speed on the screen of your Striker fishfinder. This is 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 one unit. Anytime you're 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.
