940NM lights have a lot less range than 850NM. People use the 940 because it suppose to be less visible to game than the 850. I bought used Sightmark Signal 340RT monocular with a 940NM illuminator built-in for a great price because the former owner couldn't see much more 50 yards with it. I mounted a aftermarket 850 illuminator on it and can now see past 300 yds. I have never had an animal spook from the 850NM light. Deer and coyotes can see it and will look at it but don't really seem to care. Pigs don't notice it at all. I guess if I was going to hunt a bow range the 940NM might have an advantage.

I can easily see 200+ yards with the OEM 850NM illuminator that came with my Wraiths. I do have an after market illuminator 850 that is brighter but I rarely use it, its bigger and heavier and really don't need it most of the time.

The key to getting the most out of the the illuminator is to adjust the focus to its narrowest beam, then center the beam in your scope's field of view, then tighten down the 2 allen head screws so it won't move. Then you can adjust the beam focus to a wider beam that fills your field of view and gives the best image.

I got my Wraith Mini this week and got to sight it in today. I turned if off every time I went to check the target. Turn it back on and the time and date resets back to original. Batteries were left in. I just shut it down, to save the batteries, Anyone else have this problem? Is there a fix?

I would email Sightmark technical support and ask them, their customer support is excellent and every time I've reached out they have responded promptly.

Thank You. Anybody else have this problem?

I don't have a Wraith Mini, but I have an original Photon IR scope. I had a problem with it after a while, and I second BigDad in saying that their customer service is excellent.

I just got mine today and immediately tried cycling it on and off several times and it kept all my settings. Sightmark will fix it for you or replace the scope if it's defective. They're good in the support arena!

Just got an email from them and it has to go back for repair/replace. Waiting on an RMA. Kind of reminds me of ATN.

I just received a return number to write in large letters on the package along with the address. It seems I have to pay to ship a defective product back to them. Who said they have GREAT customer service?

I did!

You may not think it's perfect, but it's light-years ahead of pretty much everyone else.

My mini had no problems in my first range usage. i will try it again this weekend
