I have a Garmin Oregon 400T.
maps – i only use the basic map, no OS, no streetmap etc but I know you can buy both. I have cached abroad using these basic maps as well and I get on very well with them
I bought mine 2nd hand and overall, it’s been amazing. Even to the point when I dropped it down a beach cliff. It landed in a rockpool, SD card and back cover floating. Everything else fully submerged. Still worked when I put it back together! 🙂
To be fair, it wouldn’t connect to my computer for a few weeks but just as i thought i was gong to have buy a new one, it must have dried out and it went back to being good old reliable Gary. Great bit of kit! 😆 😆
