Experience the Clarity of CHIRPThe Striker Plus 4 Fishfinder includes Garmin CHIRP technology for a higher level of clarity and detail. Crystal-clear sonar images provide remarkable target separation and resolution in shallow and deeper water. Bottom contours are more visible, even at higher speeds, and signal noise can be suppressed at greater depths for a timely interpretation of what's below your boat. Mark Spots with High-Sensitivity GPSThe built-in, high-sensitivity GPS finds and maintains your position anywhere you go on the water. The GPS allows you to mark waypoints for different locations. So, if the fish are biting in one spot, you can mark it and return to it on your next trip. Mark docks, boat ramps, and other locations on the lake, and create routes back to them for your next trip. The GPS also allows Striker Plus 4 to show your speed on screen, so you can be sure you're trolling at the right speed for the lure you're using or in wake-controlled areas.
