Buying Guide

Match connector and pin count

Verify the cable or adapter uses the correct connector type and pin configuration for your device or vehicle to avoid incompatibility

Choose the right power method

Decide between hardwired constant-power cables, OBD-II adapters, or USB adapters based on installation complexity and desired parking-mode features

Check IP and marine ratings

For boats or exposed installations, prioritize cables with IP68 or marine-rated construction and corrosion-resistant contacts

Consider extension length

Longer transducer or extension cables simplify routing in larger vehicles and vessels; confirm length meets your installation path

Look for interference mitigation

Select adapters and transducer extensions with shielding or designs that minimize sonar or GPS signal interference
