Here’s an inexpensive magnetic mount you can make for the HD HERO2. I purchased a 66 mm round magnet base with a 95-pound pull from our local Harbor Freight Tools (cost: $5), superglued a 1/4″ x 20 turns/inch screw (standard tripod size) into the base, and mounted the GoPro tripod base onto the screw. This magnet is extremely strong and fastens securely to the hood of my car.
I recommend placing a thin piece of paper between the magnet and the hood to help avoid scratching the paint, particularly when placing and removing the magnet.
