ADC Ridge Mechanical Altimeter
Product Description and Features
This is a compact, handheld altimeter for gauging barometric pressure and altitude. It requires no batteries, is durable, reliable, and retails for around $40.
Easily calibrated by reading the instructions and turning the altimeter scale ring. You will want a known altitude and current barometric reading for where you are when you calibrate it.
Measurements of altitude up to 16,300 ft. No metric markings.
Accurate within 50ft.
The altimeter is very sturdily built with a semi "non-slip" texture, which makes it easier to handle with cold hands.
The calibration bezel moves precisely and stays in place. It is a bit difficult to move, but that is also the sole reason it stays in place.
The scale also is marked in 100 ft. increments. (If you need more precise measurements then you'll have to spend over $150 for a quality digital version)
