QUICKLY DETERMINING HEADLAMP HEIGHT
The Sniper has two marks on its mast to assist in determining the headlamp height. Align
the aimer head with the headlamp as described on pages 9 and 10. If the top of the aimer
head is lower than the bottom mark, the headlamp is lower than 36“. If the top of the
aimer head is between the top mark and the bottom mark, the headlamp height is between
36” and 48”. If the top of the aimer head is higher than the top mark, the headlamp
height is higher than 48”. Set the beam slope knob accordingly.
