The Cardellini (LPS) RED Laser Pointer + Holder + Clamp Kit  is a modified Aurora Laser Pointer so that it can remain illuminated, instead of just being "on" when the momentary switch is depressed. It comes with a 360 degree by 360 degree locking clamp that attaches to the Mini Cardellini Clamp (included).

Laser pointers are extremely useful tools on set or out on a location night shoot. Very often, you will see either the DP, Key Grip, or Gaffer using a laser pointer to indicate a place (generally up high on a set or a stage) to a crew member where a lamp or other piece of gear is supposed to be hung or rigged. The laser pointer sends out an extremely bright red "dot", that is easy to see way up high. The First AC or Dolly Grip will also attach a laser pointer to a dolly or crane arm with a clamp and aim it at a specific mark on the ground or stage floor that corresponds to a precise location or distance from a subject. As the dolly or crane moves, the First AC and/or Dolly Grip now have a precise reference or target to aim for or judge distance with.

The Red Laser Beam has a 660nm Wavelength. 900' range! Two AAA batteries are included.
