Powerful handheld radio - this is what it should be able to do
Reliability and sufficient range are the most important criteria for a marine radio. It goes without saying that the range and frequency must comply with the regulations for marine radio in inland waters or at sea. Our handheld radios have direct access to channel 16, the distress channel. Other channels can be programmed.
The range alone does not make a good radio seaworthy. It is important that it can be operated even after capsizing. It must therefore be waterproof and floatable. It is helpful to have models that are designed so that the display points upwards in the water. An additional flashing function of the buttons makes the device more visible for help seekers as well as helpers.
Current devices can be powered from different sources. Batteries and rechargeable batteries are suitable, which can be charged with 12 volts as well as with 220 volt sockets. An energy-saving mode extends the running times. Large function keys facilitate operation, and an illuminated display is an advantage not only in poor visibility but also in sunlight.
AIS, DCS, GPS - find position and be found
High-quality devices are equipped with an Automatic Identification System. AIS provides information about data that can be important not only in an emergency. In addition to static information about the ship, routes and position are transmitted. Boats and boatmen thus become visible even at night and in fog, and the danger of collisions is minimised.
DSC, Digital Selective Calling, makes it possible to call a specific subscriber. Special frequencies are used for this purpose, which leads to better reception.
Thanks to GPS, it is not only possible for the boat operator, but also for emergency services to locate the boat after an emergency call - or independently of it. GPS uses satellites as a connection, so data transmission works almost perfectly, regardless of local conditions.
Handheld radio - modern technologies
Other features are also built into high-quality handheld radios. If a model has Bluetooth, it can be used to connect to a mobile phone without having to remove it from its waterproof packaging. Navigation systems guide boaters to their destination. In an emergency, integrated strobes use special light signals to draw attention to the position.
