easyRESCUE-DIVEpro
Emergency transmitter for diving groups with 2-level communication
Every diver must have wondered at some point what would happen if he or she is separated from their “buddy” or their group and loses orientation to the dive boat. You can wear the tiny portable easyRESCUE-DIVEpro transmitter in your vest pocket without problems when diving. And don’t panic, it’s water-resistant at a depth of more than 100 meters.
The device has been developed for use on safari boats and diving bases and has evolved from the emergency transmitter easyRESCUE-DIVE. The transmitters are activated before diving and issued to all members of the diving group with the relevant instructions for use. They then transmit a regularly recurring position report that can be received by the dive boat. All group members can thus be located at the water surface and the dive boat maintains an overview.
If the group appears out of sight of the dive boat, the Diving Guide can take his transmitter out of the bag, unfold the antenna and hold the device upwards with outstretched arm. The dive boat will receive the current position, travel to that position and take the entire group on board.
Function
If the situation described above should occur, the diver can take out his/her own transmitter, unfold the antenna and fix the device to the accompanying “alarm buoy” or hold it high in the air. The dive boat will receive a position report and can react accordingly. However, if a serious emergency situation occurs, the diver can trigger an official ”maritime distress call“ (Search and Rescue). This emergency signal is received by both the dive boat and almost all other ships in the diver’s surrounding area.
The following scenario is taking place in the background
With its integrated GPS receiver, the easyRESCUE-DIVEpro will receive a GPS fix within 35 seconds after activation, and transmit the position data together with an official emergency signal on 2 globally standardized radio frequencies. In addition to the GPS position, which is updated once a minute, data such as “course over ground” and “speed over ground” as well as an individual device ID is transmitted. These emergency signals are received by every ship in the surrounding area that is equipped with an AIS receiver. The transmission range can extend to up to 10 nautical miles or more, depending on the height of the receiving antenna. Since 2007, all commercial vessels with more than 300 BRT and/or 12 persons crew/passengers must be equipped with an AIS system by law. The number of recreational craft acquiring AIS receivers also increases each year, to enable access to the travel data and positions of commercial shipping. All these vessels receive the diver’s emergency signal on their electronic chart plotter and can initiate fast and effective assistance.
What is required to operate the easyRESCUE-DIVEpro?
The easyRESCUE-DIVEpro can be used immediately. The device does not need to be additionally registered or enrolled. To receive the “simple” position report on board the dive boat, an AIS receiver easyRX2S is required, set to the special frequency of the easyRESCUE-DIVEpro. The emergency signal can be received with any AIS receiver, and the frequencies for the position report are different for each region. The devices can be prepared for the respective region in the factory.
