The Montana is a huge device, with a very large screen too. It’s a delight to use, with intuitive menus and a touchscreen that even performed well in the rain and with gloves on. It runs on a rechargeable lithium-ion battery or 3 AAs – a really useful feature if you’re on a multi-day walk with no charging facility. PC connectivity is seamless, making it easy to download routes or upload tracks. But it’s very heavy, and scrolling is fiddly due to the marking facility which pops up if you double-click the screen. The mapping bundle is great value. For around £50 more there’s the 650 variant, with features including a geotagging camera, but this one does the job for us.
