Transmitter Position Tips

The transmitter communicates wirelessly with your compatible dive computer. On the surface, it uses ANT® technology. Underwater, it uses a sonar signal. Your body, drysuit, and dive equipment can obstruct the signal, particularly while underwater. For the best reception, all transmitters in your group should have clear lines of sight to the dive computer. To help prevent blocking the signal with your body or equipment, you should follow these tips.

  • You should install the transmitter at least 7 cm (3 in.) from your body.

  • You should install the transmitter on the same side of the tank as the wrist wearing your dive computer. For example, if you wear your dive computer on your left wrist, you should install the transmitter on the left side of the tank regulator.


    Transmitter and watch placement
  • For the best reception, you should wear the tank high on your back. This allows the transmitter to have a clear line of sight over your shoulders.


    Transmitter placement on the body
  • If you wear your tank inverted with the regulator at the bottom, you can use a high-pressure hose to relocate the transmitter to have a clear line of sight over your shoulders.

  • If you lose the signal from your transmitter, you should move your arm until the signal is restored.

  • If you lose the signal from another diver, you should change your body position until the signal is restored. If your body is between the dive computer and another diver, it may obstruct the signal from that diver's transmitter.
