Take your fishfinder to the next power level with this 1kW  20° tilted element transducer.

Airmar has taken their innovative Tilted Element™ technology to a higher power. The B164, 1kW transducer is perfect for fast, trailered tournament-sportfishing vessels that cannot have a High-Performance Fairing.

The flush mounted, stainless steel housing protrudes less than 1/4” outside your hull and can sit on trailer rollers and bunks with no damage at all. The ceramic arrays are tilted inside the housing, giving you the perfect vertical beam with maximum energy on what is directly below your boat. And 1kW takes your fishfinder to the next power.
