ok everyone so heres the new wrap on this cam, today i brought 4 paks of AAA lithium batteries and i gotta say it has improved the life of the camera by 110%, i highly recomend everyone that has this cam to get energizer lithium batteries, me and my buddie filmed for ages today and it still has full batterie power left over which is alot better compared to using normal/alkaline batteries wich run out within ten minutes of filming. The only bad thing is that it was murky as hell today because of stormy wether previously being on the prow but the pic quality was still pretty nice when we managed to hit sum clear patches of water - nice meaning good quality for a camera as cheap as this one. As for mounting to spearguns you can purchase mounting kits for it at the official website
Digital Hero Camera Home just scroll down and take a look at the Ride Hero accessorie i think it may fit alot of pneumatics if thats what you use. also the head mounts i wouldnt reccomend, i find it really annoying and when spearfishing in shallows it likes to pop in an out of the surface of the water wich makes the footage look quite Shite!
