i'm lookin to shoot some pictures of my spearfishing /freediving trips this coming summer and since i dont know about photography i would greatly apreciate any help from you guys ... i've thinking about buying a regular point and shot digital camera like sony olympus or nikon and buy an underwater housing that would fit rated to 130 ft depth ...is this a good idea?... i'm not looking for high end costly equipment but something decent i can have some fun with... thanks in advance!!
