Laser Genetics NS-300 SZ Designator


By: Dr. Jim and Mary Clary


We have been waiting for the NS-300 subzero since we got word that Laser Genetics was working on it back in 2014.  And, we have to tell you, it was worth the wait.  This night vision laser does what no other product of its kind does.  The Laser Genetics NS-300 features what is called the Advanced Laser Module Technology (ALM).  This new ALM unit is easier for the human eye to see than with most other lasers.  The 520-mm solid-state green laser allows one to paint a target out to 300 yards, or open it up to illuminate the surrounding area.  (It is actually visible for up to 3 miles... so be careful). 


For varmint and feral hog hunters, this is "just what the doctor ordered."  No more spooking the predators with spotlights. Scan the area with the NS-300, paint the target, and they are done.  We have used it extensively around the farm, and it does not spook or alert any of the critters that they are being "watched"... and that includes coyotes.  


The original Laser Genetics products were designed and developed to provide high-quality illumination that existing night vision products couldn't meet.  The new NS-300 Subzero unit takes the technology and design one step further.  This unit is lighter, ultra-compact, and provides a substantially more stable platform than previous models.


This new unit comes with a scope mount that has separate vertical and horizontal adjustments which make it easy to align the laser with your riflescope.  That, by itself is a major benefit of the NS 300 SZ.  With an MSRP of $309.99, the NS 300 isn't cheap, but given its quality and capability of operating under all temperature conditions without attenuation, it is a reasonable price.  And, after a bit of searching, we found it available online for $229.95, which is a huge value.


PRODUCT specifications and highlights:

·       520nm Class II Visible Green Laser

            This class of laser will not cause skin burns or start fires.  The only potential

            hazard is to the eyes... so, do not look into it or point it at another person.

            If by some accident the laser flashes across your eyes, blink and look away.

            The normal blink reflex is quick enough to prevent damage... but, also, make

            note...  DO NOT look at the beam's reflection - this becomes even more important

Jim has experience with lasers while working as a research scientist for the U.S. Air Force.  As such, we believe it is appropriate to reprint the warnings here that are included with the NS-300 SZ:


  • NEVER aim the laser at people or vehicles.

  • NEVER look into the output of the laser designator.

  • DO NOT ALLOW CHILDREN to play with the laser designator.

  • EYE INJURY is possible if the laser is aimed at people using telescopes, rifle scopes, spotting scopes, binoculars, cameras, or other optical light gathering instruments.

  • NEVER use the laser designator around individuals who may interpret your actions as an emergency distress call, unless it is an actual emergency.

  • DO NOT remove the safety labels on the laser designator.

  • DO NOT attempt to repair or disassemble the laser designator as it could lead to hazardous exposure.

  • DO NOT use the laser designator if the lens is cracked or broken.

  • NO MAINTENANCE or SERVICE is allowed by the owner.


REMEMBER:  Aiming a laser at aircraft, watercraft, vehicles, law enforcement officials, or other situations where vision and situational awareness are critical can cause disruptions of safe operations causing dangerous situations AND COULD BE A CRIMINAL OFFENSE (it usually is).
