Underwater Case for Shooting Triathlons

[werunhsv]

Any thoughts on using an underwater case for shooting Triathlons? I have been shooting with a Olympus TG4, but would much rather use my 5D iV instead. Everything has been in fresh water. Mostly, I shoot the start from in the water as they jump in.
