The HD Innovations UMS Claw Mount gives anglers a fast, secure way to mount a UMS setup on round rails, jon boat sides, kayaks, and other temporary locations when chasing bass, crappie, walleye, pike, and panfish with forward-facing sonar or adjustable transducer poles. This universal aluminum claw-style mount uses a 1.5 in. ball connection for the HDI UMS system, giving anglers flexible positioning without committing to a permanent install.
