Thanx Kouros, unfortunately Geocaching is not something that would interest my family so that's not really an option. I have had a look on e-bay and unfortunately the majority of units are Garmin Geko units, I'm looking for something a bit higher specced as I also inted to use it for getting to and from wreck dive sites both here & abroard but don't want to spend a lot of money as this will eat into my diving funds. What I'm really looking for is some feedback for meople who have used these units and I can then decide which one I will buy.
