The ProShot Phone Cage for iPhone 17 Pro Max from PGYTECH is custom designed for the iPhone 17 Pro Max, and it is the core of the modular ProShot imaging system. It is equipped with expansion ports that make it easy to attach the ProShot Quick-Release Grip, a 1/4"-20 socket adapter, and a cold shoe mount. The hand grips also offer a cold shoe mount that can hold accessories such as fill lights or microphones when the top Bluetooth Remote Control Module or Standard Cover Module is removed. It offers an expansion port on each side for shooting in vertical or horizontal orientation. All control buttons and ports are fully accessible. Internal silicone padding fits snugly against the phone for secure protection, and for heat transfer to help prevent overheating during extended use.
