Detailed description

The EPIRB3 Pro Cat.1 Class 2 beacon by Ocean Signal represents a major evolution in maritime safety. Equipped with an automatic release housing, it combines Cospas-Sarsat 406 MHz satellite transmission (12 W) with AIS technology (1 W) to simultaneously alert global rescue centers and nearby vessels. The integration of the RLS (Return Link Service) provides visual confirmation that the distress signal has been received, offering crucial reassurance in emergency situations.

Cutting-edge technology and NFC connectivity

Featuring a 72-channel GNSS receiver, this beacon ensures ultra-fast position acquisition. The key innovation lies in its NFC connectivity, allowing users to check the beacon's status, test history, and battery capacity directly via an Android mobile app. Unlike previous-generation models such as the EPIRB1, the EPIRB3 Pro integrates AIS for immediate local detection on vessels' chartplotters in the area. Its 121.5 MHz homing signal (50 mW) facilitates the final approach for search teams.

Robust design for automatic release (Category 1)

Designed for the harshest marine environments, the beacon is Class 2 compliant, ensuring optimal operation from -20°C to +55°C with over 48 hours of autonomy thanks to its lithium battery (LiFeS2). The Category 1 housing (237 x 191 x 121 mm) automatically releases the beacon at a maximum depth of 4 meters in the event of a shipwreck. With a total weight of 1252 g (422 g for the EPIRB alone) and guaranteed waterproofing up to 10 meters for 1 hour, it is MED and Cospas-Sarsat certified. Its mounting footprint is designed for easy replacement, offering compatibility with the drilled holes of older McMurdo E5-G5 or Jotron Tron 60S mounts.

Expert review

Pol CONIN

« The ultimate combination of satellite and local AIS alert »

The Ocean Signal EPIRB3 Pro beacon redefines offshore safety standards by combining global Cospas-Sarsat alerting with local AIS alerting. As installers, we particularly appreciate the Category 1 hydrostatic release container, whose mechanism reliably deploys at a depth of 4 meters. The addition of the RLS provides a major psychological advantage for the crew, while the NFC diagnostic simplifies preventive maintenance without risking false alerts. Furthermore, its installation footprint allows direct replacement on the templates of older competing models such as the McMurdo E5 or Jotron Tron 60S, significantly reducing refit time on the helm deck.

Frequently asked questions

Need help? Contact us

What is the EPIRB3 Pro Category 1 beacon?

This is an automatic-deploy maritime distress beacon. It combines:

406 MHz transmission (Cospas-Sarsat)AIS to alert nearby vesselsRLS to confirm signal reception

What is the difference between a Category 1 and Category 2 EPIRB?

Category 1 means the EPIRB is fitted with an automatic release mechanism. In the event of a sinking, the container opens and releases the beacon automatically at a maximum depth of 4 meters.

What is the RLS function used for on this tag?

The RLS (Return Link Service) provides visual confirmation that your distress signal has been received by global rescue centers. This offers crucial psychological reassurance in emergency situations.

How does the NFC connectivity of the EPIRB3 Pro work?

With NFC technology, you can simply bring an Android smartphone close to the beacon. Using a dedicated app, you can view:

The beacon's general statusThe history of completed testsThe remaining battery capacity

What is the battery runtime upon activation?

The lithium battery (LiFeS2) provides over 48 hours of continuous operation, even in extreme conditions down to -20°C.

Can I replace the beacon battery myself?

No, replacing the batteries yourself is strictly discouraged. The operation must be performed by an authorized professional to ensure the device remains watertight and functions correctly.

What is the purpose of the integrated AIS signal in the EPIRB3 Pro?

The AIS (Automatic Identification System) transmits a 1 W local alert signal. This signal appears directly on the chartplotters of nearby vessels, significantly speeding up rescue operations on scene.

What is the role of the 121.5 MHz frequency?

The 121.5 MHz frequency is a homing signal (50 mW). It allows search and rescue teams (helicopters, rescue vessels) to precisely locate the beacon during their final approach.

Is the beacon watertight?

Yes, the EPIRB3 Pro beacon is fully watertight. It is designed to withstand immersion to a depth of 10 meters for 1 hour.

What are the dimensions and weight of the unit?

The physical specifications are as follows:

Container dimensions: 237 x 191 x 121 mmWeight of the beacon alone: 422 gTotal weight (with container): 1252 g

Where should I install the automatic release housing on my boat?

The housing must be installed in an unobstructed location on deck. There must be no obstruction above it to allow the beacon to float freely to the surface and maintain a clear view of the sky for GNSS signal in case of a man-overboard situation.

Is the EPIRB3 Pro bracket compatible with older models?

Yes, the mounting template of the container is designed for easy replacement. It is compatible with the drilling patterns of several older brackets, including the E100/G, McMurdo E5-G5, and Jotron Tron 60S models.

What operating temperatures are supported by this beacon?

As a Class 2 beacon, it is designed to operate optimally in extreme temperatures ranging from -20°C to +55°C.

How does the beacon obtain my GPS position?

It is equipped with a 72-channel GNSS receiver. This cutting-edge geolocation system enables ultra-fast and highly accurate acquisition of your position to transmit it immediately to emergency services.

What is the estimated lifespan of the beacon?

The estimated lifespan of the EPIRB and its bracket is over 10 years, provided regular maintenance and battery replacement at the indicated expiry dates.

What happens if the tag is stored at very high temperatures?

Prolonged storage at very high temperatures can reduce battery life. It is recommended to adhere to the specified storage temperature range, which is from -30°C to +70°C.

At what depth does the automatic release trigger?

The automatic release mechanism for the container (category 1) triggers autonomously when the vessel sinks and reaches a maximum depth of 4 meters.

Should the beacon be tested regularly?

Yes, regular testing is recommended. The beacon allows for self-tests to verify battery status, 406 MHz and 121.5 MHz frequencies, AIS signal, and GNSS acquisition.

Which mobile application should I use to read NFC data?

To read the information from the tag via NFC, you must install the official Ocean Signal mobile application, which is available for smartphones running Android.
