I have
for sale an Airmar DST 800V triducer (depth, speed & temperature) and
Simrad is20 combi display, both brand new in box with
manuals etc.
I bought these as part of a larger West
Marine "sail" package but decided not to use them.
The triducer is
NMEA 2000 version with a 2m cable. The display is compatible with Simnet and
NMEA 2000.
The tricucer comes with a marelon through-hull with a handy flap/valve that stops
water gushing in when you switch between
transducer and blank (also included)
These are all you need (apart from an
NMEA 2000 or Simnet backbone), together with just one hole in the
hull, to display speed,
depth, and
water temp.
List
price is $700, will sell for $450.
