GGA free dive test

[h.m.scoop]

Finally got to test out my new GGA headphones in the water and they are great, definitely better than the first set of GGA that I tested that failed because they got swamped. The second pair off GGA are the newly designed GGA and so far I am very pleased with them. I still need to test them out on a dive to see if they are loud enough to hear them during breaths. While testing today in a free dive test I found a two toned 14k ring...

Beware, the newly designed plastic capsule covering the piezo can fail. I had one on mine leak, water got by the o-ring corroding the piezo, not sure if the capsule cap was not tightened down evenly or if the o-ring groove had something in there preventing the o-ring from sealing. Due to the design, replacement of the piezo is easy if you can solder. When I re-assembled, I added silicone sealant around the plastic capsule cap to help hold out water......

Thanks Nagov, I will reinforce the capsule cap...

Cliff,

Do you have pics of your mod, just bought a new set of GGA's and I don't want them to fail.

It's not pretty but it works... I got the Marine Adhesive Sealant from Home Depot in the paint department.
