You replied to me on ScubaBoard today concerning underwater housing for Canon 550D.
Could you please tell me if this momentary toggle switch would work underwater properly without need for additional protection? http://www.apem.com/pdf/MT.pdf
It's from one of your links. I'm also considering toggle switch with lever and hexseal boot with it. Do you have idea which option would be better?
Some minor things, Finnsub is not a finnish manufacturer, I believe they are from the Czech Republic. On the other hand there is also Scubamafia from Finland http://www.scubamafia.fi/torches-accessories-umbilical-lights-c-27_29.html . I have not seen their torches, but they claim to somehow get a 7° angle with triple XML, I wonder if this is just a bit optimistic or what optics they might use.
(I have an Aqua-Lux Laser – not a laser at all, just named that way. It’s a magnificent unit: 280x68mm, 1,4kg / 11x2.67”, 3.1lb. The tailcap is an 11mm depth of aluminium solidity. It was discontinued about 7 years ago).
EDIT: Sorry - discontinued in 1998, 16 (!) years ago.
