1. A rangefinder including: a laser ranging system for measuring a distance to a target,a display,a processor in communication with the laser ranging system and capable of producing an image on the display,an input for inputting a wind direction into the processor, wherein the wind direction is as perceived by a user and without reference to a directional measuring device, by moving an indicator around a periphery of the display image and selecting the perceived wind direction represented by the indicator, and further wherein the input for inputting wind direction is a multi-position button in communication with the processor, and wherein the processor is capable of producing an updated image on the display in response to manipulation of the button; andan input for inputting a wind speed into the processor by selecting a numerical wind speed value from a menu. 2. The rangefinder of claim 1 wherein the indicator is an arrow pointing the direction from which the wind is blowing. 3. The rangefinder of claim 2 wherein the arrow points towards the center of the display. 4. A rangefinder including: a laser ranging system for measuring distance to a first target from a first location,a display,a processor in communication with the laser ranging system and producing an image on the display,an input for providing a wind direction data into the processor, wherein the wind direction is as perceived by a user and without reference to a directional measuring device, by moving an indicator around a periphery of the display and selecting the perceived wind direction represented by the indicator, wherein the indicator is an arrow pointing towards a center of the display and moved around the periphery of the display to also point in a direction the wind is blowing, and further wherein the input for inputting the wind direction is a multi-position button in communication with the processor, and wherein the processor is capable of producing an updated image on the display in response to manipulation of the button;an input for inputting a wind speed data into the processor by selecting a numerical wind speed value from a menu, andan inertial navigation unit in communication with the processor, the inertial navigation unit capable of detecting a directional orientation,the processor capable of storing the wind direction data and the wind speed data for calculating and displaying a new wind speed and a new wind direction when the rangefinder changes position, based on a data from the inertial navigation unit. 5. The rangefinder of claim 4 wherein the processor further calculates and displays a windage setting and an elevation setting for the first target on the display. 6. The rangefinder of claim 5 wherein the processor uses the stored wind speed and the stored wind direction data from the first target and further calculates a windage and an elevation setting for a second target measured from a second location based on the stored wind speed and direction data. 7. A method of viewing information in a rangefinder, comprising the steps of: providing a wind data to a processor in the rangefinder, the rangefinder also comprising a display, a laser ranging system, and an inertial navigation unit, the wind data provided using an input for providing a wind direction data into the processor, wherein the wind direction is as perceived by a user and determined without reference to a directional measuring device, by moving an indicator around a periphery of the display and selecting the perceived wind direction represented by the indicator; wherein using an input for providing the wind direction comprises using a multi-position button to move an arrow-shaped indicator around the periphery of the display until the indicator points in the direction a user perceives the wind is blowing, andan input for inputting a wind speed data into the processor by selecting a numerical wind speed value from a menu;providing a ballistics data to the processor in the rangefinder,taking a distance measurement to a first target from a first location using a laser ranging system of the rangefinder, the processor calculating an elevation and a windage hold value based on the distance measurement taken, the ballistics data, and the wind data provided; andviewing the calculated elevation and the windage hold values in the rangefinder display. 8. The method of claim 7, wherein the ballistics data is stored in a ballistics data processor. 9. The method of claim 7, comprising the additional steps of: taking a distance measurement to a second target from a second location using the laser ranging system of the rangefinder, the processor calculating an elevation value and a windage hold value based on the distance measurement taken, the ballistics data, the wind data provided, and the data from the inertial navigation unit; andviewing the calculated elevation and the windage hold values in the rangefinder display for the second target. 10. The method of claim 9, wherein the wind data and the ballistics data is the same for both the first and second target. 11. The method of claim 7, wherein the indicator is movable in 30 degree increments.
