With depth, speed, and temperature data surfaced in a single transducer, the P66 reduces helm clutter while providing clear, actionable sonar readings. The dual‑frequency setup expands coverage from shallow bays to deep channels, and the adjustable beamwidth lets you tailor detail and range for your fishing environment. The transom‑mount design fits 2°–20° transoms on many boats, and the 800–1,200 ft depth range ensures you have reliable data in open water. If you’re using a 6‑pin Garmin sounder, remember to use adapter cable 010-11612-00 for compatibility. The package includes installation instructions to help you mount correctly and avoid damage to your boat. Note: Prop 65 warning applies.
