The earlier ND_3 will no0t work in cold below 35 degrees and the lens gradually gets mopre and mre dots until it is unusable. I have had this lase for 3 years and pid $300 for it. it definitely is not worth the money as a hunting tool because it is not rugged enough for sustained use. If this new one has overcome these flaws, I would be interested.
Pros: Long range
Cons: lens gradually becomes covered with dots
