Summary: Don't waste your money on the eXplorist 310. I bought one eight months ago to use for kayaking. I wanted to know speed, distance, route, etc. It does give you those things, but it is not at all intuitive to operate and the display is very difficult to read in the sun.
Summary: Not sure why Magellan is not compatible with Mac but they should advertise that upfront. I bought the GPS and it arrived on time but I cannot use any of the special features not can I download the Fishing Hot Spots since they only work on a PC. Waste of my money...
Summary: I really wanted to like this GPS but Its cramped button configuration makes it difficult to operate efficiently and the directional toggle is jerky and imprecise. The screen is also small and I found it's performance to be slower than some of the older units I have owned in the past.
Summary: My wife purchased this for me as a gift. used maybe 6 times and went to start it up one day but it just shows a white screen. Called Magellan and they tried very little to help then said that I would have to buy a new one as they would not repair it.
Summary: Pros: Good price, nice features Cons: Good features do not do you any good if it won't talk to the birds above. The nice folks at Magellan are sending me a replacement because mine does everything but get fixes from the satellites. Once I get the replacement, I'll do another review.
Summary: Terrible little device. Takes forever to power on and lock on. The menu system is infuriatingly bad. And the CPU is too slow, so when you press any button, it takes up to 5 seconds before anything changes on the screen, so you're always waiting for the device to catch up to your commands.
