A couple weeks ago I went on a trip with my brother and he has the H2O Ifinder and I have this simple little Garmin GPS 72. I was really looking hard at getting the H2O, and my brother picked one up at my suggestion. Short story is we used mine all weekend. His took for ever to get a signal and lost signal ALL THE TIME!! I didn’t have a problem with mine, and never have. It works great for what I need. I was just considering getting one with more options and ability to use chips, etc… But if all of them work like that I am way better off with my cheap little 72. Do you need an external antenna to get this unit to work. I had mine side by side with his on the dash and mine never lost signal and the H2O hardly ever had enough signal to navigate. I removed my unit and it didn’t help a bit. I am really wanting to upgrade my handheld, is there anything anyone can suggest as far as the H2O, or is there a better unit out there that I can use chips, mapping, etc…????
Thanks much
