Thanks. I was looking into maybe housing an R10, but Nauticam and all the other brands making aluminum housings do not support that model. Only Ikelite do as far as I could find, and 60m/200ft max use is very limiting so I might just hold on a while longer to a Nauticam housed RX100V.
Anybody using their Ikelite housings deeper than their 60m/200ft rating or have experience doing that? I know some aluminium housings can be used beyong their rated depth without leaks. The buttons can get sticky though, and some manufacturers do offer upgraded springs for deeper diving.
