13. ff that is higher than the tuning fork speed For example if the menu is set at 50 it will not read speeds below 50 mph so a fork speed of 40 mph would be too low to register Also note that only the vehicle type setup menu settings will display the 1 10th digit The Peak Hold Function Peak The Peak Hold button activates the automatic top speed lock When the Peak Hold J Hold mode is on the PEAK HOLD icon will appear on the display Only the highest speeds will be displayed When tracking a baseball pitch the peak speed will be the same as the release speed since a ball only slows down after it is thrown When the PEAK HOLD icon is OFF the gun will continuously display speeds as they change When tracking a baseball pitch the display would start by showing the release speed but then rapidly roll down and hold the last speed reading at the plate TIP The Stalker keeps both the Peak and Last speeds in memory As long as a reading is on the display either by releasing the trigger to hold the reading or pressing the Recall Speed button to bring it back on the display you can switch back and forth between the last recorded speed and the peak speed by changing the Peak Hold setting For example If you are clocking baseballs and the Peak Hold is ON after the pitch is thrown change the Peak Hold setting to OFF to see what the speed was at the plate The Setup Menu Setup The Stalker radar gun has several different menu settings desi
