Telrad Dew Shield
Manufacturer Part # 3993
This lightweight plastic dew shield attaches to the Telrad finder using existing screws at the rear of the finder body. It pivots forward to cover the Telrad viewing plate to retard the formation of dew when the finder is not in use. Simply pivot the dew shield back for an unobstructed view through the Telrad. Friction holds the dew shield in either an open or closed position. The amount of friction can be adjusted by tightening the two screws that hold the dew shield to its metal attachment brackets.
This dew shield is a simple device that can greatly extend the time you can use a Telrad before dewing fogs the Telrad viewing plate. It also increases the lifespan of the Telrad reticle, which can become damaged from the constant collection of dew on its surface.
