Product details

Notes on programming:

This PLB must be programmed with your personal data before dispatch. The appliance will not function without prior programming.

The programming of this data must be carried out by us, you cannot do this yourself.

As a rule, we program a PLB so that it can be used as an EPIRB. This means that the device is programmed and registered to a vessel and not a person. To do this, we need your personal data such as MMSI, boat name and call sign.

Please add the above-mentioned programming accordingly and complete the form in full.

If you require programming for a specific person, we can also do this for you.

The registration of the device to the respective country code must, in any case, be carried out by us.

Please let us know in which country you would like to register the device. Since there are no authorities for PLB emergency beacons in Germany, you can, for example, find information about the further procedure on the website of the English authorities ( https://www.gov.uk/register-406-beacons ) In addition, the registration of the PLB should be carried out on the website of the IBRD (International Beacon Registration Database) ( https://www.406registration.com/ ). We would also like to point out that, in accordance with the regulations of the respective country, you must register the EPIRB personally as the licence holder with the competent authority.
Jotron's Tron SA20 PLB is a personal locator beacon with global emergency alert coverage. Thanks to its rugged and compact design the distress transmitter is ideal for carrying with you at all times. The Tron SA20 PLB is also one of the smallest 406 MHz rescue devices on the market.

RLS function
The RLS (Return Link Service) function is a two-way communication type between your EPRIB and the rescue centre. The RLS system gives you the peace of mind that your distress message, which was sent via the EPIRB frequency, has been received by the rescue coordination center. As soon as your distress message is received by the responsible authority, the RLS LED on the Tron SA20 lights up. The RLS signal is sent via the Galileo satellite network from the rescue control centre back to the EPIRB, which triggered the distress message. This confirmation that rescuers are aware that an EPIRB has been activated and know its location helps reduce the stress associated with accident situations.

Many thanks to SVB and Jotron. This beacon is a must-have.
I'd like to share my experience with this personal beacon.

It's a high-tech product. Lightweight, with an extremely long battery life (until 2035), satellite communication, and although it's not considered a 100% EPIRB due to regulations, it perfectly performs what you would expect from an EPIRB, and in any environment (marine or otherwise), with worldwide coverage.

The problem arose with registration.
Europe is a bureaucratic maze that complicates the registration of survival beacons. Specifically, I bought it unregistered out of ignorance, only to discover that the cost can skyrocket. I even spoke with the very helpful Jotron technicians, who acknowledged the problem. For potential future buyers (I highly recommend this product), I suggest ordering them programmed for the UK and then registering them yourself with your personal information on the UK website for beacons. Easy and free. As far as I know, other European countries are a mess of non-free registration entities and require specialized personnel to handle the process. The UK is simple, free, and accepts beacon registrations for non-residents. I must thank SVB for their enormous help in registering the beacon and their attention in finally getting everything working. And of course, thanks to Jotron. For the price of this technology and the battery life, it's a must-have for adventurers and sailors.
