Humminbird 740210-1 MEGA Live TargetLock Adapter Kit for Ultrex

Upgrade your fishing game with the Humminbird TargetLock Adapter Kit for Ultrex. This independent TargetLock mount keeps the MEGA Live Imaging beam fixed on your chosen structure even as your boat moves, while you retain full control of your trolling motor and Spot-Lock. It’s the ultimate fusion of pinpoint sonar focus and seamless motor operation.

MEGA Live Imaging delivers real-time, high-definition sonar with no gaps, so you can watch fish and structure unfold in front of you. The MEGA Live Sweep provides a continuous 120-degree sweep out in front of the boat, helping you identify targets and contours without ever losing sight of the action—perfect for scouting structure, cover, and reaction fish, all while you stay in command of the trolling motor.

Why you’ll love it
