The Amron International Amcom II 2-Diver Portable Rechargeable Communicator - Internal Charger with Wireless Tender Option has many versatile features and options. The most unique feature of the 2825A series is separate channels and volume control for each diver and the tender for both uplink and downlink paths. Each diver may have different equipment such as microphones and speakers or different listening and speaking characteristics.
The volume on the Amcom II 2-Diver Portable Rechargeable Communicator - Internal Charger with Wireless Tender Option can be set individually for each diver and tender to a level that is optimal for them. Both divers can be set up on 2-wire and/or 4-wire mode, or one diver on 4-wire mode and the other on 2-wire mode or any combination of the two modes.
The Model 2829-11 Wireless Tender Kit 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 Model 2829-11 Wireless Tender Kit 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.
