User manual BUSHNELL SPEEDSTER III

[. . . ] To install, remove the battery cover (A) by depressing both sides of the handle bottom (B). Place the battery cover (A) back onto the handle so that the textured side of the battery cover matches the textured surface of the handle grip area. For example, with the TRIGGER engaged, you can see the RealTime speed measurement of a moving object as it accelerates or de-accelerates. the Bushnell Speedster is a handy , multi-functional speed gun for all kinds of sports enthusiasts. [. . . ] Once you are there, you will see that the PITCHER text is in reverse image. now press the ENTER button so that "1" is in reverse image (Figure 8). Then press the ( ) button to increment to pitcher number 2. You are now ready to keep statistics for Pitcher 2. Follow the same procedure for future pitchers. hOW TO EDIT BALL / STRIKES DATA You can make edits to the BALL and STRIKE data in the PLAYER EDIT Screen (Figure 7). To get to the PLAYER EDIT screen, press the PAGE button until it appears. To move from PITCHER to BALLS, press the ( ) arrow key until BALLS text is in reverse image. then press ENTER so that the numerical ball data is also in reverse image. At this point, you can add ball count by pressing the ( ) button, or ( ) to decrease ball count. When you are satisfied with the edit, press ENTER. As the angle of incidence increases, if you move either right or left of this direct line, the accuracy will decrease. The measured speed will decrease as you move off this centerline. This phenomenon is called the Cosine Effect. It is so called because the measured speed is directly related to the cosine of the angle between the Speedster and the target's direction of travel. Figure 9 below relates this to a little league baseball field. According to the table, assuming the average distance from the pitcher to catcher (y) is 60 feet, there will also be an average distance behind the catcher to the seats (y1). this is assumed to be an average of 20 feet. So the total distance from pitcher to Speedster (ytot) is 80 feet for this example. This is the straight-line direction of ball travel, not the distance from the pitcher to the actual Speedster position, which is R. Off center of the direct pitcher to catcher line, then you have an angle of incidence of 10°. Most importantly, this gives you an error of 1. [. . . ] SETUP and PLAYER EDIT Screens i) Used to move up one line position ii) Used to increment/change selected parameter when editing a field b.
