Northstar TD1008 Fishfinder Transducer B744VL-10N

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 has a Northstar 10pin connector and is sold by Northstar as part TD1008.
