No,afraid not, but thinking of the K V H TracVision G4, any reason why you are considering the Raymarine, thought K V H where the leaders in this stuff, or was that just the salesman talking?
I believe you are correct where KVH are concerned, but the Raymarine 45 is about half the price of the KVH G4 equivalent. Price being an issue where trying to convince management that it is what we need on board here.
The pre-production testing was done on a boat based in lowestoft, just down the road from you. Its still on it, I might be able to organise a looksee, if you definately interested in one.
And yes, they do work well. And yes I can do a good deal on one, supply only or fitted.
