DT/DST800 Transducers

The DST800 and DT800 transducers are designed to use the P617V or B617V housings with integral valves. Inserts are shipped with a yellow O-ring installed as shown below.

The DST800 senses depth, speed and temperature. The DT has no speed sensor. These models are for use with instruments, and are not fishfinder transducers.

The transducers can also be used with P17/B17 non-valve housings. The transducers are shipped with a spare black o-ring, and the yellow O-ring must be removed and replaced with the black version in order to make a correct seal in the P17/B17 housings.
