I have a Tomtom for use in the car but have tried it on the boat, it gives SOG and shows that you are on the river most of the time although Salhouse Broad is shown as a field. I also have a Lowrance iFinder Go which I have switched on all the time as I am attempting to chart the Broads on my PC. I find the advantages of the iFinder are that the batteries last for 48 hours (so long as you dont use the backlight), it records a track of where you have been and from a SOG point of view it gives a decimal place of your speed. The speed limits are designed to keep wash to a minimum and that requires speed through the water so I rely on a NASA log for boat speed. Stan
Sounds like you're keen on the iFinder Go? I've been thinking about getting one mainly because it looks good value for the £85 they seem to be going for now. I have a TomTom Go Classic but as you say it's not really for boating.
The Lowrance seems to come with UK mapping installed.. What's the quality like?
