We (Portishead Lifeboat
) run a system of 6 Gecko helmets, one of these being their Video Helmet
Each helmet has got the Gecko supplied headset, however, our system works on the Peltor DectCom
system all suitably 'waterproofed' using a combination of IP rated boxes (for the base station) and Aquapacs (for the users handsets), rather than their standard VHF radio setup....the DectCom works on voice activation, therefore we do not have the in-line PTT switch.
I have to be honest, we have managed to 'kill' a few headsets, but this is mainly due to the conditions we operate in. The quality (before being subject to a few bad weather trips) is very good, but like all electronics, the presence of salt water can soon take its toll!!.
The Gecko helmets (as many other readers will confirm) are very good, they can appear a bit tight when new, but soon loosen up.
If you want any more info, let me know.
