Waterproof spotting scopes

Dust-, waterproof

— spyglasses with enhanced protection against dust and moisture, and often also officially certified according to a certain standard, most often IP. The degree of protection varies, but most often this feature implies at least dust resistance (dust can penetrate inside, but does not affect operation) and rain protection (against splashes at an angle of up to 60 ° to the vertical). And the most advanced models are completely sealed (in particular, this feature is typical for gas-filled cases, see the relevant paragraph). However, if the pipe is planned to be used in adverse conditions, it is necessary to clarify the specific degree of protection before buying.
