Questions and Answers for Ocean Reef Integrated Audio/Video System (Gamma 105):

  • Dennis:

    will the Gamma 105 work at 300, can you extend the wire for the camera? I need to buy equipment to service a petroleum gas line at 200 will this equipment be suitable? need to film and record the operation. thanks

    Greg  (Certified Scuba Instructor at

    The Gamma 105 can work at 100 meters (300 feet), with a special cable. When ordering the cable, please allow for line slack caused by currents and equipment. The system can allow for NTSC or PAL formats when recording. The gamma 105 supports either hard wire or wireless audio communications. If multiple divers are going to be in the water, wireless audio communications works the best.

  • Joffre:

    I can not find the battery charger. Can you help me with specifications of this charger in order to purchase it in Radio shack? Amps? Volts? Power? etc? Thanks a lot

The Gamma 105 is an integrated audio/ video system consisting of the M105 Digital and a CCD Micro Video Camera, which may be installed in an underwater housing, attached to a Neptune mask, or held by the diver. This system makes it possible for those on the surface to communicate with an unlimited number of divers, within the range of the M105, while simultaneously monitoring the underwater video footage. The camera is hardwired via a 50 m (164 ft) cable to a 7 inch color LCD monitor. The Gamma 105 system includes the following items:
Ultrasonic surface communication unit: 10 m (33 ft) transducer cable, microphone, external power supply cable, audio port, headphone port, volume control, and loudspeaker

CCD Micro Video Camera with underwater housing and mounting bracket

50 m (164 ft) camera cable

7 inch 16:9 color LCD monitor, speaker, audio and video port, brightness and color controls

Video port for external video recorder or monitor

12V battery

Battery charger connector

12V battery charger
The M105 Digital is a surface to diver communication unit which allows surface personnel to talk with divers in the water and vice versa. The unit uses a 6V DC lead battery, allowing up to 48 hours of operation, or may be hardwired to a 12V DC source. The system is activated only hen the transducer is connected, preventing unwanted loss of battery power. To start communication, the transducer must be lowered into he water; the standard cable length for the transducer is 10m (33 ft). Transmission is activated by pressing the microphone button, which will emit a short beep letting divers know transmission is about to begin. It will return to receive mode when the button is released.
