MOB1 Baliză de urgență AIS rescuME Autonomie baterie 7 ani >24h

The Ocean Signal MOB1 rescueME is an ultra-compact man-overboard (MOB) locating device. It uses AIS (Automatic Identification System) and DSC (Digital Selective Calling) technologies to immediately alert your own vessel and nearby boats in case of a man-overboard situation.

The MOB1 beacon battery provides an operational autonomy of over 24 hours in continuous use, even in extreme conditions at -20°C. In storage mode, the battery life is 7 years.

The beacon is designed for seamless integration. To install it:

Pass the provided strap around the bladder of the lifejacket. Attach the mount to the MOB1 so that it is positioned outside the inflation tube. This way, it will not interfere with the deployment of the jacket.

It is compatible with the vast majority of AIS chartplotters and modern ASN (DSC) VHF radios. These devices must simply comply with current maritime standards to process MOB alert messages.

Upon activation, the beacon performs two simultaneous actions:

It transmits an AIS signal that displays your precise GPS position on the chartplotters of nearby boats. It triggers an audible alarm on your vessel’s VHF radio via an ASN message.

Yes, it is designed to withstand the most extreme marine environments. It guarantees waterproofing up to 10 meters depth (2 bars) for more than 60 minutes.

This is one of the most compact tags on the market. It weighs only 92 grams and has minimalist dimensions of 134 x 38 x 27 mm, which prevents it from hindering crew movements.

Yes, the beacon integrates a high-intensity flashing light (strobe). This light signal is essential for facilitating visual detection of the victim at night or in poor visibility conditions.

The MOB1 uses local frequencies (AIS and ASN) to immediately alert nearby vessels and enable rapid recovery by your own crew. The PLB1, on the other hand, transmits a distress signal via satellite (406 MHz) to alert global terrestrial search and rescue coordination centers.

Absolutely. It is designed to tolerate operating temperatures from -20°C to +55°C, withstand thermal shocks (such as sudden immersion in cold water) and withstand drops up to 20 meters in water.

Yes, when properly secured and integrated into the inflation system of an automatic lifejacket, the beacon activates automatically as soon as the jacket inflates. It also has a manual activation mode if needed.

Yes, the beacon has a battery test function. However, the manufacturer recommends not performing this self-test more than once per month to avoid prematurely reducing battery life.

It is equipped with a 66-channel high-performance GPS receiver. This system ensures highly accurate positioning and rapid position updates for rescue services.

To fully utilize the alerts emitted by the beacon, your boat must be equipped with an AIS receiver (connected to a display or chartplotter) and an ASN-compatible VHF radio (Digital Selective Calling).

The beacon transmits at 1 Watt for the AIS signal (providing excellent local range) and 0.5 Watt for the ASN alert message to the VHF.

During the test, a flashing code indicates the system status:

1 green flash: Normal operation.Multiple flashes (2 to 6): Indicate a fault, such as a frequency generation issue, low battery, or lack of GPS signal.

The battery has a 7-year lifespan. Once this period has elapsed, or if the beacon has been used in an emergency situation, the battery must be replaced by an Ocean Signal authorized service center to ensure the maintenance of waterproofing and performance.

Although its design is optimized for automatic integration on the inflation tube of a lifejacket, the beacon can also be worn on the body (in a secure pocket) and manually activated in case of man-overboard.

The beacon transmits on international maritime safety frequencies: 161.975 MHz and 162.025 MHz for the AIS system, and 156.525 MHz for ASN alert messages.

No, the MOB1 tag does not require any subscription. Unlike some private satellite communication tags, it uses standard maritime radio waves (AIS and ASN) whose distress use is entirely free.
