SP25MMGP is a versatile camera adapter that allows you to mount GoPro action cameras, including GoPro HERO4, HERO3+, HERO3, HERO2, and HERO onto mounts accommodating the 25mm (1 inch) ball pattern (including Arkon Robust Mount models and RAM Mounts—sold separately). Unscrew the adapter to reveal a 25mm swivel ball to 1/4”-20 camera mounting bolt for mounting small action cameras as well. It's a 2-in-1 mounting solution for all types of cameras. This package includes only the 25mm Swivel Ball to GoPro Lateral Screw Pattern Adapter. (Mounts, holders, and devices sold separately.) Secure the GoPro adapter onto any mount accommodating the 25mm (1 inch) ball pattern, then insert the GoPro camera using the lateral screw pattern. Use the SP25MMGP adapter with current Arkon Robust Mount Series Models RM080AMPS (Heavy-Duty 80mm Suction Mounting Pedestal with 4-Hole AMPS Head), RM2XAMPS (Heavy-Duty 4-Hole AMPS to 4-Hole AMPS Mounting Pedestal), or RM0802T (Heavy-Duty 80mm Suction Pedestal) to make them GoPro-compatible.
