3.3 FLOAT FREE BRACKET
The Float Free bracket, type FB-40, is an automatic bracket, were a hydrostatic
release mechanism (HRU) releases the EPIRB from the bracket when reaching
2-5 mtr below sea-level.
The HRU is type approved by Jotron and special adjusted to the FB40 includes a
special bolt with adjusted fittings. This module is supplied as a HRU-Kit.
The Tron 40VDR Float Free Capsule is activated automatically when immersed
