Frequently Asked Questions

What is the difference between the PAL and NTSC Gamma Alpha?

The Gamma Alpha is sold in a PAL version (SKU OR033105, UPC 764500000808) and an NTSC version (SKU OR033104, UPC 764500000815). Choose PAL for regions and equipment that use the PAL standard, and NTSC for regions and equipment that use NTSC.

How long does the Gamma Alpha's battery last?

The Gamma Alpha runs on a 12V rechargeable battery rated for 24 hours of stand-by autonomy. It recharges with an external 12V power charger; the quoted 24 hours is stand-by autonomy, not continuous operating time.

Can the Gamma Alpha communicate with two divers at the same time?

Yes. The Gamma Alpha has two audio plugs and two video plugs, and a switch lets the surface operator choose communication with diver 1 only, diver 2 only, or both divers together, while a separate video switch selects which diver's camera feed appears on the monitor.

What underwater unit does the Gamma Alpha use?

The Gamma Alpha pairs with the Alpha Pro X-Divers hardwired underwater communication unit (code OR033135), connected through a 50 meter (165 ft) surface/diver cable. This underwater unit is used with Ocean Reef Full-Face Masks on the diver's side of the system.
