Description

This altimeter measures air pressure, converts to altitude, and displays numerical values on the LCD. Reset altimeter at launch point with pressure at firing point (Reset button switch is located on the upper left outside of the LCD screen. ) and then convert the air pressure to the highest altitude when the air pressure is at its lowest after launch. The height can be selected in both metric and feet. There is a power on/off switch on the side. When the voltage of the battery is low, the battery mark will be displayed. English instruction manual and Japanese instruction manual are included. In addition, when replacement batteries are difficult to find, you can use 4 layers of LR41 1.5 V alkaline button batteries (diameter 7.8 mm, thickness 3.4 mm, weight about 0.61 g). The weight is lighter (total: about 2.44 grams) but you dont know how much time it can be used (not measured). This is a domestic inventory product. Brand new and unused.
