    The Wireless Tender Option is a perfect complement to our Two Diver and Three Diver communicators. Amron's Full Duplex (Simulcom®) Wireless Tender is designed for the top-side tender to communicate to divers with hands-free operation and no required buttons to push. This wireless unit allows mobility for the tender while checking equipment and still maintaining constant contact with the divers (4 wire mode only).

    Amron's Wireless Tender Option includes: (1) 2829-11 wireless headset and transceiver. Additional 2829-11 Wireless Headset and Transceiver Kits can be purchased for use with the Wireless Tender Option as "listen only" devices, as only one headset on the system can listen and talk priority to the divers. The design allows the capability to add an unlimited number of remote listen only headsets for the topside personnel. The units operate on 2.4 GHz up to a range of 120 yards (110 meters).

    The transmitter/receiver unit is housed in a rugged plastic casing that can be clipped to a belt or slipped into a pocket. A single charge of the NiCad battery from the included AC adapter is capable of operating (transmitting and receiving) continually for up to 5 hours. In standby mode, battery will last for up to 8 hours. The standard headset is a tough over-the-ear single ear muff design with adjustable boom microphone. Also included is a smaller, lightweight headset/microphone for added mobility.

    Depending on the age of the unit, existing non-wireless communicators in the field can be sent back for retrofitting. Contact your Amron Representative today to learn more!

    Product FAQ's

    Ask a Question

    • Can you stack the banana plugs from the diver's communicator cable so you can have two divers on each diver channel?

      Although it may be possible, we strongly discourage such operation. The added workload would cause overheating and stress to the amplifier card. Prolonged use in this condition will eventually cause permanent damage and failure to the amplifier card.

    • What type of cable do I need to connect my Amron communicator to my Outland video system?
      Amron communicators and Outland Technology’s video systems have a RCA Phono Jack. To connect the two systems together, you will need an audio cable with RCA Plugs on each end.

    • Should I use a GFI when operating my radio off AC power?

      When operating your Amron Diver Communicator on AC, it is critical to use a Ground Fault Circuit Interrupter (GFCI) or isolation transformer for tender and diver safety. Surges and spikes are common on AC lines found on ships, generated locally, or at the end of long extension cable runs and can exceed 1kVolt. Such surges and spikes can cause the fuse to blow on the amplifier card assembly. The power supply is designed so that such a failure will be isolated and will not cause a safety issue to the tender or divers. It is strongly advised that your Amron Diver Communicator be operated on an AC circuit with a high quality surge arrester or an AC isolation transformer.

    • Why does the speaker on my communicator sound muffled?
      The simplest way to fix this issue is to unplug the red banana plug from the red microphone 5-way binding post on the communicator and rotate it 180 degrees then reinstall it. This should fix your problem. For a more detailed explanation of what happened, please read below. The issue is not with the communicator, it is with the wiring of the umbilical. There is always the potential for wiring the speakers and microphone out of phase, similar to wiring the speakers on a car stereo system. There is an orientation to the banana jacks and they should be wired for proper phasing with the communicator. A banana plug does have an identified ground side marked on the plug. Amron always sets up their umbilicals so that the ground side is located on the left side so the user can consistently plug in their umbilical and avoid phasing issues. If a banana plug is plugged upside down or is wired out of phase, the sound quality will be significantly reduced. If the phasing is out and the orientation of both plugs are the same, then the banana plug wiring should be reversed on “only one plug” to avoid this issue again. It does not matter which plug you choose to reverse the wiring on.

    • Can I operate my communicator while I’m charging the internal battery?
      Yes, however, the charger will charge the battery at a slower rate as some of the charger power is being used to operate the communicator.
