  • Volume setting for each diver and tender to their individual comfort level

  • Both divers can be set up on 4-Wire Mode or 2-Wire Mode or any combination of the two modes

  • Ability to use both dynamic and preamplified diver microphones with a unique circuit that detects microphone type and automatically adjusts volume levels

  • Weatherproof panel microphone for greater voice intelligibility

  • Communicator can be left on charge indefinitely without damage to the batteries or communicator (/23 and /24 versions only)

  • Communicator can be operated directly from the charger where AC power is available (/23 and /24 versions only)

The Wireless Tender Option is a perfect complement to our 2-Diver and 3-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!

Tech Note

All communicators will transfer topside noise to the diver when using the radio speaker only. To eliminate background noise and achieve clear concise communications, use a push-to-talk microphone or a headset or a remote walk & talk with a headset.
