Summary: I have spent 5 uninterupted hours attempting to figure this thing out. NO luck. I am fairly computer literate...but this has kicked me. I think too it may not be operating properly. It seems to get stuck on one screen and I have to turn it off and back on.
Summary: I am not sure if the product does what it says because I couldn't figure out how to work it! I am not a computer geek but I do consider myself very computer literate and this thing is just too confusing and the manual is of no help at all! I bought this as a gift for my husband. He gave up after about 30 minutes and I gave up after an hour. The unit was returned the next day.
Don't forget to count in £150 mapping software, this does not replace a map or a compass.

Summary: The Summit HC has proven useful for geocaching and following waypoints for routes marked only by GPS, however this does have it's flaws at the same time. The Compass does not work, full stop. I have calibrated it many times with little success. It will never show your real direction. Ever.
