The new W470 device is a compact personal safety device, designed to guarantee the safety of each member of a vessel’s crew or any other professional crew working at sea. It can be fixed to self-inflatable jackets via the tear-to-open tape retainer or with the handy clip provided for fixing to the inflating mouthpiece.

Should the wearer fall overboard, the W470 starts working automatically thanks to the sea sensors situated on the rear of the device and transmits a radio signal that can be used to locate the crew member.

The W470 is fitted with an activation/deactivation knob and a safety lock to prevent the device from being accidentally activated. The device is also equipped with a high-performance light signal (LED) to aid in the localization of the crew member during conditions of poor visibility, as well as a large Test or Manual Activation push button.

To ensure the device is working properly and to check the battery level, the user needs to make sure that the activation knob is in the OFF position before pressing the Test button. Out at sea and with the activation knob in the ARMED position, the user can press the push button to send out the alarm signal if they fall overboard.

The W470 simultaneously emits a number of SAR signals including an AIS message (AIS MOB on channels AIS 1 & 2) and a homing signal at 121.5 MHz, in compliance with the ETSI 302961 standard. The emission of several signals increases the chances for people in distress to be located by SAR rescue units that receive the signals.

A sophisticated integrated GPS receiver provides the location of the crew member.

The batteries supplied with the device (three LiMnO₂ 3-volt batteries) have a guaranteed life of 5 years (in normal weather conditions) and can be replaced directly by the user.

The W470 is an extremely easy-to-use device and, thanks to its ergonomic design and the shape of its controls, can be easily activated even if the user is wearing gloves and/or protective gear, such as on an offshore platform.
