They have a suplier in UK. I have the Geonav4CXS handheld and it is a very reliable piece of kit. OK the batteries can be a problem sometimes, but it comes as standard with a charging cradle and some other goodies. Another good point is, it can be plugged into your laptop for full map and chartplotting, then just store it on the handheld.The Geonav 6 sunshine is also a very good fixed GPS chartplotter, it has won awards for best GPS chartplotter and they are reasonably priced.
