This is a step by step instructable to create your own wrist mount for use with the standard or the underwater GoPro housings. Also at the end I will include 2 additional mounts.
Ankle Strap or some sort of strap. This was purchased at Sports Authority for $11
Curved GoPro mount
5 inch zip ties (2)
1/8 inch drill bit
Drill a hole in each of the 4 corners on an angle as shown.
Carefully remove some of the adhesive backing using a knife.
Thread the zip tie through the holes as shown. It must go under the mount as shown to allow installation and removal of the clip. Do not connect the tie until you thread it through the strap as shown in the next step.
Attach ties and connect on bottom as shown. Clip excess.
Dog stick mount. Drill a few holes with a countersink so the screws sit flush with the mount. Give it to Rover and get some great footage!
Expandable paint stick pole. Drill 13/16 inch hole in end of pole and thread in 1/4 - 20 bolt. Cut off head of bolt with hacksaw and now you have a long pole for any camera.
