The Airmar B164 is a flush-mount, 1 kW dual-frequency thru-hull transducer built for center-console and trailered vessels with hull deadrise angles between 8° and 15°. Its patented Tilted Element™ design angles the ceramic arrays internally so the acoustic beam fires straight down — no fairing block required. The low-profile bronze housing protrudes less than 6.35 mm below the hull, allowing the boat to sit on trailer rollers and bunks without interference. A Mix & Match cable (sold separately) is required to connect to your display.

Features:

• 1 kW power output compatible with any 600 W or 1 kW echo sounder
• Dual-frequency operation: 50 kHz at 22° beamwidth for depth to 549 m (1,800 ft); 200 kHz at 6° beamwidth for depth to 244 m (800 ft)
• Tilted Element™ ceramic array delivers a vertically aligned beam without an external fairing
• Low-profile bronze housing extends less than 6.35 mm (0.25") below the hull — trailer-friendly
