Looking back on this thread, it seems that some people have bought the Sena headsets, similar to my homebrew DIY sets that I built about 18 months ago.
Some of you may have read my piece in MBY when I explained how I built a couple my DIY sets for a friend who keeps his Sealine in Brixham.
He is blind and his wife drives the boat so the extra communication aid has been very useful.
They are so pleased that they looked into importing and reselling the Sena ones here in the UK.
Well, it seems that he has been able to beat all the previous prices that I've seen for these headsets.
I had a chat with him over last weekend and this is the site that he has put together.
So, if you are looking to enjoy your "close quarter" boat handling more - especially when working with SWMBO, this IMO is the cheapest place to get them.
