Tripod Mount
Using a GoPro Tripod Mount for the iPhone
Go Pro Tripod Mount is a cool thing to add to your collection. It basically makes any GoPro accessory available to any other technology device.
For example, if you have an iPhone XS Max, you can use a simple tripod adapter and the GoPro mount to connect the iPhone XS Max to a GoPro Suction cup accessory. Now you can exchange accessories and limit the amount you carry.
Cheap Enough to Get it
Obviously this won’t work in all accessories, but it’s cheap enough to have on - just in case you find that using a smartphone would be better than the GoPro. You can find a mount for about $4 on eBay or in various kits on Amazon for about $7.
