Ikelite rating margins?

[northernone]

Wonder how deep you've repeatedly taken the ikelite dlsr housings. Mine is 200 ft (60m) depth rated.

Any rule of thumb for knowing their failure depth? Would considering swapping out the springs if that's the primary limiting factor.

Mines been a little bit below 60m with no apparent change.
I regularly take it beyond 50m.
