Jotron Tron SART20 (3200054)

In many distributor catalogs, 3200054 is used as the purchasing identifier for the Tron SART20 kit supplied with a standard bracket (often a bulkhead/wall bracket), aligning with Jotron’s product offering “with bulkhead bracket” for shipboard installation and emergency removal.

Design and Features

Radar-transponder operation for X-band detection

Tron SART20 is designed to be detected by X-band radar, meaning it is intended to be “seen” by the vast installed base of marine navigation radars on SOLAS vessels and many non-SOLAS craft. In practice, this provides a practical “last-mile” localization aid during SAR operations: once a responding vessel or aircraft is within radar range, the SART’s response pattern helps guide the final approach.

Survival-craft form factor and mounting options

Jotron markets Tron SART20 as a compact survival-craft device, supported by multiple mounting approaches:

Bulkhead/wall bracket for vessel stowage and rapid release in an emergency
Lifeboat bracket for mounting on or near lifeboats
Liferaft mounting options, including lanyard and telescopic pole usage to raise the device and improve line-of-sight performance

The user manual describes practical mounting methods for life rafts (e.g., using a 10-meter lanyard) and highlights the value of a telescopic pole to elevate the SART, reflecting a common principle in VHF/radar survival equipment: height improves detection range.

Simple emergency activation with clear feedback

Tron SART20 is designed for rapid activation under stress. Jotron’s operating instructions describe an activation ring that is pulled to place the switch into the ON position, after which the unit provides visual and audible confirmation. The manual also notes that when the SART is within range of an active X-band radar, its internal loudspeaker activates and the flash rate increases—helping survivors recognize that rescue radar is “seeing” the unit.

Serviceability: battery module replacement

Unlike sealed, disposable safety devices, Tron SART20 is described as supporting easy battery replacement, and the user manual provides step-by-step instructions for replacing the battery module (including O-ring replacement and silica gel use to manage moisture). This supports regulated inspection regimes and lifecycle planning for commercial fleets.

Technology and Specifications

Core operating concept: 9 GHz radar SART

A radar SART is designed to respond to radar pulses and create a recognizable display pattern on the rescuer’s radar screen. Tron SART20 is explicitly described as a radar transponder designed for SAR operations, with the key requirement that the responding vessel or aircraft is operating X-band radar within range.

Operating duration and emergency-use model

Jotron emphasizes that Tron SART20 is emergency equipment and that it should only be used in an emergency. The user manual states the battery lasts for 96 hours from activation, a design parameter aligned with prolonged search windows and adverse conditions where survivors may require extended time before recovery.

Accessories and installation ecosystem

Jotron highlights a “wide range of accessories” and maintains separate accessory listings (e.g., lifeboat brackets) and dimension drawings, supporting standardized fleet installations and retrofit programs.

Warranty and documentation set

The Tron SART20 brochure lists a 5-year warranty and Jotron’s product page aggregates a compliance and documentation package (manuals, declarations, transport safety information, and certificates). This documentation-oriented approach is typical for GMDSS equipment where carriage, inspection, and certification workflows require traceable records.

Applications and Use Cases

SOLAS/GMDSS carriage for survival craft

Radar SARTs are widely carried as GMDSS equipment on SOLAS-class ships and survival craft to support rapid location once SAR assets are in the vicinity. Tron SART20 is marketed directly for lifeboats and liferafts, reflecting its role as a survival craft locator used after abandoning ship.

Offshore workboats and remote-area operations

In offshore or remote operations, distress response can involve long transit times and challenging sea states. A radar SART can be valuable during the final phases of the rescue because it leverages a capability most responding ships and many aircraft already carry: X-band radar. Elevating the unit with a pole, as described by the manual, is particularly relevant in rough seas where wave clutter and low antenna height can reduce detection performance.

Training, inspection, and fleet standardization

Commercial operators frequently standardize survival equipment across fleets to reduce training overhead and simplify inspection. Tron SART20’s shared accessory ecosystem and documented maintenance procedures (including battery replacement) support these operational practices.

Advantages / Benefits

Broad compatibility through X-band radar detection

Because X-band radar is common on SOLAS ships and widely used for navigation, a radar SART provides a locator that does not depend on specialized receivers beyond standard marine radar. Tron SART20 is specifically positioned as “detected by X-band radar,” reinforcing this practical advantage.

Long operating endurance for extended rescues

The stated 96-hour operating duration supports extended rescue windows, especially in severe weather, remote waters, or complex SAR coordination scenarios.

Field-ready mounting options

Jotron’s lifeboat brackets, lanyard mounting, and telescopic pole guidance support real-world deployment where survivability and signal performance depend on keeping the unit upright, elevated, and clear of obstructions.

Maintainability and lifecycle planning

The combination of battery replacement procedures, seal/O-ring guidance, and published documentation supports predictable GMDSS servicing and inspections over the device lifecycle.

Comparisons (if relevant)

Radar SART vs AIS-SART

A radar SART (like Tron SART20) produces a recognizable response on X-band radar displays. An AIS-SART instead broadcasts AIS distress messages that appear as a target on AIS-enabled chartplotters and AIS receivers. Jotron markets both device classes (Tron SART20 and Tron AIS-SART) and supports a shared accessory ecosystem in its product literature, allowing operators to select equipment based on bridge electronics, regulatory preferences, and SAR doctrine.

Tron SART20 vs older SART designs

The Tron SART20 brochure emphasizes robustness, compactness, and maintainability (battery replacement and accessory options) as modern operational features compared with earlier generations of more limited or less service-friendly devices.

Pricing and Availability

The Tron SART20 is widely available through maritime safety and GMDSS distributors. Pricing typically varies by region, kit contents (bracket type, accessories), and service support. Public reseller listings commonly sell the unit as a kit including the SART20 radar transponder + bulkhead bracket, with retail pricing often in the hundreds of US dollars (varying by market).

FAQ Section

What is Jotron Tron SART20 (3200054)?

The Jotron Tron SART20 is a 9 GHz radar search and rescue transponder used in survival craft to help rescuers locate a distress position using X-band marine radar.

How does Tron SART20 work?

When activated, Tron SART20 responds to X-band radar signals and generates a distinctive radar display pattern that helps responding ships and aircraft home in on the survival craft’s location.

Why is Tron SART20 important?

It provides a practical “final approach” locator during rescues by leveraging equipment that most responding vessels already have—X-band radar—helping reduce search time when rescue assets are nearby.

What are the benefits of Tron SART20?

Key benefits include X-band radar detectability, a documented 96-hour operating duration after activation, a broad accessory ecosystem (lifeboat brackets, lanyard, telescopic pole), and maintainability through battery module replacement procedures.

How do I mount Tron SART20 for best performance?

Jotron’s manual recommends securing the unit vertically and as high as possible (for example using a telescopic pole or lifeboat bracket) and keeping it away from nearby metal objects that can affect performance.

Summary

The Jotron Tron SART20 (3200054) is a compact 9 GHz radar SART designed for survival craft use under GMDSS practices, enabling rescue forces to locate a distress position using standard X-band radar. Its emphasis on long emergency endurance (96 hours), straightforward activation, flexible mounting options (including lifeboat brackets and telescopic pole use), and serviceable battery replacement has made it a widely deployed solution for lifeboats and liferafts in commercial maritime safety programs.
