I use a regular lazer with GEN3 NVG now and am wondering why I would need this for hogs? The green or red lazer just shows white in the NVG kinda like the EOTECH hologram site on low intensity.
In a tactical situation if the other side had NVG and you were using this, you would just be making yourself a target, IMO.
Hint: a laser that you can't see can still blind you...but you won't realize that you are being blinded until it is too late. Black ops has used UV lasers for exactly this purpose. An IR laser is less energetic than a UV laser and would take longer to work, but it could still blind.
