Magnetic Quick Release Mount for GoPro HERO13/12 Action Camera

Give it a higher recoil and make it out. The special size S5 wire will fit a real spring socket. Press the socket to lock. The length of wire must always be in front of the spring. For the best ejection force, it is very important to calculate the angle at which the wire is wound from the outer ring. If the calculation of the degree is wrong, the degree of winding on both sides must be as close as possible to 100% of the same size. If this point is not equal, it will cause the truck to tilt. Wire diameter: 4.0. Material: steel. Color: silver. Package contents: 2 x land surfboard spring. Only the above package content, other products are not included. Note: Light shooting and different displays may cause the color of the item in the picture to be slightly different from the real thing. The measurement allowed error is +/- 1-3 cm.
