Seafrog Carbon Fiber Float Arm GA-10 D80 8" 600G

This arm is made out of CARBON FIBER which makes it light for travel and very practical.
Float arms are typically used in scuba diving, to increase the buoyancy if you are carrying heavy gear. By attaching the arm to underwater photography equipment ex heavy-duty lights, you can move more freely with a weightless system and navigate your underwater housing and get some nice shots or videos.
