Raymarine A66092 Fishfinder Transducer B744VL-RAY

The B744VL is a long-stem version of the B744V depth, speed and temperature thru-hull fishfinder with an external fairing that can be cut to match deadrise angles of up to 24 degrees. See the datasheet posted below for stem length information. The B744VL has identical performance to the B744V and is for use on boats with thicker hulls.

This version of the transducer has a Raymarine connector for the DSM30 and DSM300 sounders and is sold by Raymarine as part A66092 (previously sold as E66057).
