This Side Grip Accessory from Amphibico is designed to be used with their Rouge Underwater Housing for the RED Scarlet and Epic Cinema Cameras. It simply screws onto the front left side of housing to allow single-handed shooting underwater. This accessory is a dummy grip that does not replace the control grips, but offers easier control and handling for shooting in certain scenarios. It's made of aluminum and features a foam covering on the grip itself for a comfortable feel.
