my Aquatica 20D housing is 5 years old. it was serviced once by Reef when they installed a 6-pin for the H&W about 3 years ago.
i preparation for my next dive trip, i noticed that a couple of the top buttons didn't feel good, so i pulled the worst one and indeed it had serious corrosion in the area of the o-ring. talked to Backscatter (which is close by) and they persuaded me to send the housing in for service.
just got an estimate for $50 for four new buttons, $60 for o-ring kit, and $450 for "annual service labor" at $100/hour.
what's your experience with frequency of service (i do 30-40 dives/year on liveaboards and rinse after every dive)?
is there any particular magic to servicing this myself? - certainly pulling the buttons is not black magic.
the housing doesn't leak
would certainly like to hear Viz Art's opinion
