GARMIN eTrex30xJ

Purchased in 2019, GARMIN eTrex 30xJ in perfect working condition. Japanese Topographical Map V6 is pre-installed. I bought it for mountain climbing in snowy areas, but I no longer need it, so I am selling it. The box is not included, but it comes with a Japanese operation manual. The LCD screen protector is also already applied. There may be minor scratches, but it was used while hanging from my neck, so it has never been dropped. How about it for winter mountains where whiteouts are common?
