Haga Altimeter with Leather Case

Altimeter Saves Costly Field Time by Making Height and Slope Measurements Simple

Haga Altimeter measures the angle of elevation and height is indicated directly on the scale for various known baselines.
The Altimeter consists of a gravity-controlled, damped, pivoted pointer and a series of scales: 15, 20, 25, 30 and chains (66'L) and a percent (gradient) scale. The desired units for the baseline scales are assigned by operator in ft., yds. and meters. Baseline length is selected by turning a knob to the desired scale, which eliminates reading errors since other scales are out of view.
The Altimeter is hermetically sealed in a light metal case with a pistol grip for easy, steady handling and accurate results. 6"H x 7"W x 1"D. Complete instructions are included.
