After replacing my 23 year old Datamarine instruments a little over a year ago with a Garmin
instrument package, the Garmin
(Airmar) DST 800Triducer is failing. It works about 60-70% of the time but otherwise it slowly blinks showing the last depth
it could read.
I have checked all the connections and the rest of the system (including my older 4008 GPS
and the GMI displays) all work fine.
Garmin support says that it does not repair Airmar and that the unit is now out of warranty after one year and one month.
I see from the specs that for the triducer, the depth
puts out only 100W as opposed to 150W for the DT800. However the failure to read is not depth related. Having Google
the DST800 I see other posts with similar problems. Are there any solutions?
Given how poorly paddlewheel speed sensors perform I am thinking about dropping that feature but the DT800 says it is for 16-24 degree dead-rise
