Description
Airmar B164 Bronze 1kW Tilted Transducer | Boat Supply Store
Designed for trailered vessels and hulls with moderate deadrise angles, this Airmar B164-20-MM thru-hull transducer eliminates the need for a fairing block, ensuring clear sonar returns and compatibility with trailer rollers. It delivers a robust 1 kW power output across dual frequencies of 50 kHz and 200 kHz, providing depth readings up to 1800 feet at 50 kHz and 800 feet at 200 kHz. The low-profile 1/4" bronze housing extends minimally below the hull, making it an optimal choice for boats up to 36' LOA with fiberglass or wood construction.
Key Features

Common Concerns Answered
Does the Airmar B164-20-MM require a separate cable?
Yes, the Airmar B164-20-MM requires a separate Airmar Mix & Match cable, which needs to be purchased in addition to the transducer. This ensures compatibility with various fishfinder brands and models, but adds to the overall investment and installation planning.
Can I get better target detail with a CHIRP transducer?
While the B164-20-MM offers excellent dual-frequency performance, CHIRP technology provides a wider range of frequencies for enhanced target separation and detail in specific scenarios. If your primary need is advanced fish detection with CHIRP, you might consider Airmar's CHIRP transducer lines.
Is the installation difficult for a trailered boat?
The installation is rated as moderate (3/5) and requires drilling a hole through the hull, proper sealing, and wiring. However, the flush-mount design of the B164-20-MM simplifies the process compared to transducers requiring a fairing block, making it manageable for those with some marine electronics experience.
