I'm not sure this quite qualifies as vintage... but the dive computer I bought back in the early 90s has long since lost it's battery charge. It is a ScubaPro DC-11 and the insides (from the back) are encased in a semi-hard 'gel'. Getting to the battery will require cutting out some of the gel to obtain access and then of course replacing the gel w/ something similar that is waterproof.
Any ideas what the clear stuff is they poured in there?
I'm fairly certain it went in as a liquid and then dried or cured to a semi-hardened somewhat stiff gell-like state. It appears to be in a hard plastic case sealed (single piece) from the top (screen) and sides and the back was left open. They then put in the electronic boards, screen etc. Then they poured in a liquid that cured to a semi-hard state. Finally they used a dab of silicon and glued on the back (not shown) which had holes.
I also wonder if the gel state of the sealant is important for how this device measures depth.
I'm about 99% sure it is not silicon - at least not the type one would buy at the hardware store to seal up a window or something.
One thought is that it could be some form of formeable urethane.
Googling found little info on the DC-11 and pretty much nothing on replacing it's battery. At this point it's a goner so I figure at this point I have nothing to lose by experimenting w/ options on resealing it... Battery is avail for less than $10, the sealant is the mystery here.
Anybody have any ideas?
Has this been attempted before and generally not met w/ success?
thanks,
