There are many compact Sports camcoders on the market, and quality wise, GoPro produce some of the best, even though their not a bargain.
My trip up Benn Nevis last October was really memorable, but i was afraid to take my normal camera, simply because of the possibility of heavy rain, condensation getting into the electronics, at a much higher level.
I need not have worried, as the weather was fine, but there is alway's that doubt.
Once it's in its protective fully waterproof casing, the GoPro, or similar SportCam, can withstand the elements, and still take gorgeous video or still photos.
Any advice or opinions would be much appreciated, as currently i have a thick wedge of readies waiting to buy one, but want to know what current users thing about theirs.
