Spinlock Ocean Signal AIS MOB2 Unit

Overview

The Spinlock Ocean Signal AIS MOB2 Unit is the world’s smallest Class‑M approved AIS Man Overboard (MOB) device with integrated VHF DSC. It is supplied by Ocean Signal and designed for seamless integration into Spinlock Deckvest life‑jackets, either retrofitted or factory‑installed.

Key Features

• Combined AIS & VHF DSC Alerting – Transmits your precise position via AIS and simultaneously activates a DSC distress call to nearby vessels.
• Class‑M Compliant – Fully meets international standards for MOB beacons.
• Compact & Lightweight – Up to 50 % smaller and 20 % lighter than competing Class‑M products, weighing only around 92 g.
• Manual or Automatic Activation – Activates on inflation of the life‑jacket or can be manually triggered.
• Integrated GNSS (GPS & Galileo) – Provides fast, precise location fixes transmitted via AIS within seconds.
• Dual Strobe Lights – White and infrared LEDs improve visual detection in daylight and low‑light conditions.
• Long Battery & Operational Life – Non‑replaceable lithium battery with up to 5‑year shelf life and 12+ hours continuous operation even in sub‑zero temperatures.
• NFC Smartphone Connectivity – Allows programming of MMSI numbers and diagnostics via the Ocean Signal app.
• Visual DSC Confirmation – LEDs confirm receipt of DSC distress acknowledgements.

Installation & Use

The unit mounts to the life‑jacket’s oral inflation tube using the supplied clip and activation ribbon. When the bladder inflates, the antenna deploys automatically and triggers the device. NFC technology allows secure programming of the vessel MMSI number and real‑time device status checks using the Ocean Signal app. DSC operation can be set to open‑loop or closed‑loop depending on user preference.

Benefits to Spinlock Life‑jackets

• Seamless integration with Spinlock Deckvest models, ensuring automatic activation on inflation.
• Minimal form‑factor maintains comfort and buoyancy without interference.
• Rapid rescue response within seconds of activation.
• User confidence supported by intuitive testing, diagnostics, and battery status monitoring.
