Works great, replaced expensive winter 2 1/4 altimeter that didn’t

October 7, 2019

Nice little altimeter. I’m replacing the older, similarly sized altimeter in a large motorhome, and this was a perfect, economical match. It is accurate at sea level with the current local altimeter setting dialed in. The case is plastic, but seems quite adequate.
