Benefits of using

Jotron Tron SART20 increases the chances of detection in emergency situations at sea. When the lifeboat or liferaft is within the X-band radar coverage, the transponder transmits a signal, helping search and rescue teams navigate to the distress location faster.

Compact, buoyant, and waterproof design makes the device suitable for installation on ships, lifeboats, and liferafts. Users can detach the device from the bracket and activate it quickly when needing to abandon ship.

Long operating time increases rescue opportunities in prolonged rescue situations. With 96 hours standbyand in appropriate configurations. These technologies help improve the quality of positioning data when the operating area has corresponding augmented signal support.8 hours continuous operation, the device meets SAR requirements well in harsh marine weather and environmental conditions.

The common use of accessories with and the helps ship owners, fleets, and service units standardize accessories, brackets, poles, protective bags, and maintenance battery kits. This reduces spare parts inventory and simplifies maintenance.

Suitable for

Jotron Tron SART20 is suitable for:

• Commercial vessels.
• Cargo ships, container ships, bulk carriers.
• Oil tankers, chemical tankers.
• Passenger ships.
• Offshore fishing vessels.
• Offshore service vessels.
• Lifeboats, liferafts, and survival craft.
• Ships requiring SART equipment as per SOLAS/GMDSS regulations.
• Ship owners who want to choose a radar SART instead of an AIS-SART according to equipment requirements.
