It won't fog up if you don't use the osmo in the water without a case before putting in in the case. I have never had my Osmo overheat. I leave it on all dive but usually only take under 10 min videos at a time... Over 100 dives with the Osmo, I had it freeze up once but was able to restart it under water.
Hello @Fisshy,
That's a nice recipe for a certain dive profile:
(A) Depth within the OSMO ACTION 3 non-case rating;
(B) Recording time of approximately 10 minutes;
(C) Using direct water cooling.
You are having no problems.
My dive profiles are a bit different than that, so my recipe is:
(D) Depths closer to the OSMO ACTION 3 rating, or just unwilling to expose to salt water;
(E) Of approximately 45 minutes (or more, the battery quits at about 53 minutes right now);
(F) Using indirect water cooling (i.e. fresh water flooded case).
I am having no problems.
When you start running your rig at depth for longer periods of time we can talk along the same basis of comparison.
I never got the camera wet, but I dive where the humidity is typically 99%+.
Perhaps if I load the camera into the case in the hotel room I may have better results, but I am happy with my results now.
Using my method, I have 1ATM pressure in the case, no fogging, no overheating. No problems.
For shallower stuff and snorkeling, I might try your recipe and see.
If I ever do, I'll report back.
