thanks for your reply but drilling holes in a unit is not a good idea. eventually the corosion due to salt
will end up on circuit boards and switches, soon after that the unit will die.these units are supposed to be sealed and back filled with a neutral gas like argon, the facgt that they condensate would suggest that the last part of the process is not being applied.
Our unit is mounted on a 8,5 m open RIB
, we selected the unit based on the dealer's advise and a 3 year warranty advertised on the product. we were going to buy a garmin
3110C but at the time the production of the units was delayed and our new dive RIB
and club members could not wait any longer. So we went with a product we had not heared of, trust the manufacter's claim. Maybe THAT was our mistake!!!
