Thommen Altimeter

The universally acknowledged best analog altimeter is the Thommen Classic. Accurate to 10 feet elevation, it’s intuitively easy to set and read, and it has none of the tiresome trickiness of digital altimeters. Altitude is work; altitude is location. It’s good to know exactly where you are.
