By attaching the "ball adapter for Gopro" to the "Carbon Telescopic Arm" (sold separately), you can use it as a telescoping selfie stick when swimming and taking underwater photography. This time, the INONs unique handle allows you to securely hold your camera in place, so you can take stable videos in the water without worrying about the power of water flow. All accessories are intended to be used in the water for durability, corrosion resistance, and can be safely used in the sea. In addition, when using the "Carbon Telescopic Arm" the lens becomes a front heavy when you install the "Mega Float Tube" (sold separately), the lens will lose weight in the water, and it will be slightly buoyant so you can take long shots without fatigue.
