Sweet camera and easy to use with decent quality. I used mine on the head strap and on a 4 foot PVC pipe behind me (better setup).....very cool for video and still frame shots.....make sure to have some sort of leash or floatation device set up with it..although probably not necessary with chest strap.....I donated mine to the Pacific but will be getting a replacement soon
If you mtn bike, it works well with the helmet harness (chest strap would be even better) and it also works well hooked to the helmet snowboarding
have fun with it
