more than one keyed beep. When you are done entering keyed beeps you can either
press SET without entering a number to return to " TIMER COMMAND" - or you can just
push the GO button to start the string.
Go ahead and press the GO button. When the timer hears your 6th shot it will start a
secondary timer and give you a yell 1.5 seconds later. At first you're just getting the
magazine to the gun at the beep. After some practice you find that you're almost back on
target at the beep. The feedback of the timer allows you to objectively evaluate
equipment and technique. You could also use multiple keyed beeps off of the same shot
to break the reload down some more.
Keyboard Lock Out:
In order to prevent accidental resetting of the timer during a shooters run (a problem in
movement stages where the RO runs with the shooter and leaves his finger on the GO button)
the MKIV XP has a keyboard lockout feature.
To activate it push the OPTN button until the timer asks " Lock out go keys? " Push YES and the
timer will lock its' keyboard after the next GO command. To reset the timer push the REVIEW key.
This time the timer asks " ENABLE GO KEY? " Push YES and you're back in business.
The PAR and DLY keys will remain hot. They are far enough out of the way that this does not pose
a problem. We wanted to keep those commonly used features easily accessible.
Lead Calculator:
The second option on the Timer Mode OPTN menu allows the shooter to calculate lead based on
the velocity of the bullet and target, and the distance to the target. Note that this is the lead in a
vacuum. No allowance has been made for the deceleration of the bullet. At close pistol ranges
(25 yards) this error is small. However we do not recommend this function for use at long range.
