Design your own compass
In the majority of modern sport compasses, liquid is used to reduce needle oscillations. When the ambient temperature decreases, the volume of liquid is reduced considerably more than the material of the compass capsule. This can lead to the formation of an air bubble in the compass.
«Moscompass» products, like liquid compasses produced by other companies, have guaranteed functioning at temperatures above zero (0 to + 50 degrees Celsius).
At temperatures below zero, the formation of bubbles in compasses is possible (but it is not obligatorily). When a compass is placed in warm conditions, bubbles tend to disappear, and in future, they might not appear even in cold weather (plastic material after such "training" becomes more elastic).
To guarantee the work at temperatures below zero, we offer you a compass without liquid (model "Winter")
The use of a compass at the height of 500 metres above the sea level may also lead to the formation of air bubbles.
If a bubble appears during the warranty period and does not disappear at room temperature in the plain landscape, the compass can be replaced under warranty.
