I would like to get a GPS that I could mount on my bike , it must be water proof , I have hand held GPS’s and I have a water proof unit on my boat that I could adapt and double dip with it , but it is big and has a lot of stuff on it that I don’t really need on the bike ———-the depth finder and water temperature could be usefull , LOT OF LAUGHS ———- having been a fisherman for years I really like Garmin , what are you guys using ?????
