B44 Transducers

The B44 was the first triducer produced by Airmar, measuring speed, temperature and depth in one unit. It differs from the later 'V' versions by the lack of a valve in the housing.

The retaining clevis pin enters through the side of the threaded portion of the bronze housing. There is a noticeable flare on the top surface of the main body of the transducer for better contact with the fairing block.

There was no available high-speed fairing. Speed inserts were originally without flow stability fins and were painted blue. Later inserts were made with fins for better speed accuracy.
