Mcmurdo McMurdo SmartFind G8 PLUS AIS Cat.1 Float Free EPIRB

The new Smartfind G8 PLUS AIS beacon takes all of the features of the old G8 AIS, such as a highly accurate position indication, multiple distress frequency trasmission, and AIS trasnmission to aid local search and rescue, and adds a new IR light to aid searchers in pinpointing the casualty in low visibilty conditions. 

Combining the global 406 MHz professional search and rescue alert, with the localised locating and tracking power of AIS, the McMurdo G8 AIS PLUS beacon is a true must have companion for anyone undertaking open sea passages. 

Key features of the McMurdo G8 AIS PLUS EPIRB Beacon

  • The SmartFind G8 PLUS AIS EPIRB is MEOSAR Compatible® for enhanced detection and location performance (see below for more information on MEOSAR) 
  • Now with Infra-Red (Night-Vision) optical signal to aid detection of survivors in low light conditions. Infrared can be detected at greater range and in poorer conditions than standard EPIRB lights, therefore further accelerating recovery times.
  • QUADROTECH® EPIRB, with four search and rescue frequencies, the SmartFind G8 AIS supports the Alert, Locate, Tracking and Recovery elements of search and rescue
  • Greater location detection speed and accuracy, as the multi- constellation GNSS receivers work with a wider range of satellites including Galileo and GPS.
  • McMurdo SmartFind EPIRBs meet the new GNSS requirement which raises the minimum requirements for new EPIRBs being sold globally.
  • False activation protection and multiple self-tests also offer total user confidence.
  • Peace of mid from the unparalleled marine heritage, commitment to quality and a history of innovation, customers know they can trust McMurdo when their lives are at risk. This is backed up by a 5 year warranty*

This is the Category 1 approved version. Category 1 EPIRB models are supplied inside an auto-housing and are automatically deployed and activated when in contact with water (although they can also be manually activated).

Included: SmartFind G8 Auto Float-Free Housing (Category 1)

A fully protective, spring loaded enclosure, the auto-housing automatically deploys and activates the EPIRB when it is submerged between 1 - 4m. The SmartFind G8 auto-housing incorporates fixing points which ensure previous McMurdo auto-housing units can be retrofitted with minimum impact, when upgrading your vessels EPIRB.

Understanding the MEOSAR Ecosystem

Cospas Sarsat has rolled out a new search and rescue infrastructure known as MEOSAR. The aim is:

  • Determine beacon location within 5km, 95% of the time, within 10 minutes.
  • The full MEOSAR constellation will comprise more than 70 satellites
  • Near instantaneous beacon signal detection using bent pipe technology — average 46 minutes faster compared to LEOSAR
  • Reduced response times with multiple signal bursts to improve speed and accuracy of location calculation
  • Close to 100% reliability due to multiple antenna systems and MEOLUT networking
  • Lives have already been saved with the early operational MEOSAR through faster alerts and greater accuracy, for example in Australia.

*5 year warranty requires registration of the beacon
