Summary: I bought this unit after watching u.tube reviews and reading about it.ifound however that its display screen size is difficult to read ,even with every concievable map you could add. My son bought a montana 650 ,i would have been better off buying that instead .however yes it will give you very basic info about where you are..i used it during a 70.5km zodiac trip at night and without the aid of lights..i got there and back.
Summary: The case is a little large for my Oregon 450 but holds it in place securely with the connecting clip and velcro. I am sure that they could have come up with a neater design and it is pricey for what it is. Other disadvantage is that the connecting method means that it has to be undone to take the back of the Oregon to change the batteries. Good but only 3 stars.
Summary: This is my second walking GPS so I knew what to expect - unfortunately things did not go as I expected. Only swapped to this Garmin Dakota 20 as I could not get Windows 7 drivers for my old Magellan Explorist and it was hard to transfer files to other apps. I really can't believe why Garmin can supply a totally inaccurate basemap with a GPS capable of much higher accuracy.
Summary: I've had this a few months now and overall pretty pleased, but two things worthy of note: 1. The unit has lost memory three times - batteries have been full and I've loaded it with a route and it's just reset itself when I've gone to use it next. Very annoying if you've planned a walk and are relying on it as everything is gone - all setings, time, date, country, your route, waypoints etc. You have a new factory setting device. 2.
