At least one of those lenses includes a reticle. An optical device and a processor are also located in the housing. A wind speed sensor is mounted to the housing and configured to send a wind speed signal corresponding to a wind speed to the processor. The processor calculates a wind speed based at least in part on the wind speed signal, and wherein the processor sends an output signal corresponding to the calculated wind speed to the output device. ## Claims ### Claim 1 An optical device comprising: a housing containing a plurality of lenses, wherein at least one of the lenses comprises a reticle;
