The W470 MOB AIS is an extremely small and light personal safety device. Working on VHF maritime band as MOB AIS and Homing VHF 121.5 MHz, complete with GPS positioning. This Personal locator beacon with AIS can be worn around the neck by its flexible silicone rubber covered antenna or it can be fitted directly into the lifejacket or lifeboat.
It can be manually activated (by pressing the large button) or automatically through the marine sensors. It is equipped with built-in high efficiency flashing led.
The W470 Personal locator beacon with AIS simultaneously emits a number of SAR signals including an AIS message (AIS MOB on channel 1 & 2) and a homing signal at 121.5MHz in compliance with the ETSI 302961. The emission of several signals which are received by the SAR rescue units, will increases the chances for people in distress to be localised.

MORE DETAILED INFORMATION
The new W420 “RESCUE-ME” is a compact personal safety device, designed to guarantee the safety of crew members. It applies easily to an inflatable lifejacket through the removable bracket or by using a textile hook.
Should the wearer fall overboard, the W420 starts working automatically thanks to the sea sensors situated on the rear of the device, transmitting a radio signal that can be used to locate the crew member.
The W420 is fitted with an activation/deactivation knob and a safety lock to prevent accidental activation. The device is also equipped with a high-performance light signal (LED) to aid in the localisation 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 must ensure 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 immediately send out the alarm signal should they fall overboard. The W420 sends a radio message on international maritime AIS channels 1 & 2, receivable by any AIS equipment on board or by surrounding rescue units.
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 2 years (in normal weather conditions) and can be replaced directly by the user. The W420 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.
