McMurdo Smartfind S20 is a revolutionary development in safety at sea as one of the first products to scale down AIS search and rescue technology for personal use.
In the event of an emergency at sea, McMurdo Smartfind S20 sends your GPS co-ordinates once a minute for a minimum of 24 hours to all AIS equipped vessels within a 4 nautical mile radius to request assistance. The first message is generally sent within 15 seconds. The Smartfind S20 also feature a flashing light to help rescuers pinpoint your precise location in the water.
Weighing just 120g Smartfind S20 is designed to be attached to a lifejacket and with compatible lifejackets* can even offer semi-automatic activation.
• Manually activated personal safety device
• Easy to operate
• Automatic deployment option*
• Designed to be mounted on a lifejacket using the clips supplied
• Transmits GPS tracking information over AIS
• Compact and lightweight
• Waterproof, buoyant and submersible to 5 metres
• Unique ID
• Flashing LED light
• Minimum 24hr continuous operation
• 7 year battery storage life
* Automatic Activation - When Smartfind S20 is professionally fitted onto a certified lifejacket it will automatically activate transmission when the lifejacket is inflated. For an up-to-date list of compatible lifejackets please see McMurdo's website.
Unlike most satellite enabled notification devices, the McMurdo Smartfind S20 requires no monthly or annual subscription, making it a cost effective GPS enabled emergency beacons available for long term use. Whether you’re a commercial vessel, a fishing trawler or leisure craft, an AIS MOB device should be considered essential safety equipment for every member of the crew working on deck.
This device should only be used in situations of grave and imminent danger to life. False alerts endanger lives and cause expensive disruption to Search & Rescue services. Deliberate misuse of the device could result in a penalty.
Compatibility: Note that most modern AIS plotters and DSC VHF units comply with the standards for receiving MOB transmissions. However, it is recommended that you check with your equipment manufacturer to ensure compatibility. DSC functionality may vary - or be disabled entirely - according to the regulations of individual countries.
