EPIRB3 Pro kat. 1 třída 2, AIS, RLS a NFC

This is an automatic release maritime distress tag. It combines:

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

Category 1 means the beacon is equipped with an automatic release housing. In the event of a shipwreck, the container opens and automatically releases the beacon at a maximum depth of 4 meters.

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

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

The tag's general statusThe history of performed testsThe remaining battery capacity

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

No, it is strictly inadvisable to replace the batteries yourself. The operation must be performed by a certified professional to ensure the device's waterproofing and proper functioning.

AIS (Automatic Identification System) transmits a local alert signal at a power of 1 W. This signal is displayed directly on the chartplotters of nearby vessels, significantly speeding up rescue operations in the area.

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.

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

The physical specifications are as follows:

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

The container must be installed in an unobstructed area on deck. There must be no obstruction above it to allow the beacon to float freely to the surface and have a clear view of the sky for GNSS signal in case of a shipwreck.

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

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

It is equipped with a 72-channel GNSS receiver. This cutting-edge geolocation system enables ultra-fast and highly accurate position acquisition for immediate transmission to emergency services.

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

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

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

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

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

The EPIRB3 Pro holds numerous international certifications, including:
