Filter with Ultra dot

Does anyone use the filter that comes with the ultradot? What conditions would warrant its use?

Only when the target is too bright in the direct sun. But I find sunglasses equally effective.

I put mine on to see if it would help make the dot be a dot. it didn't. I read some of what Dr. Wong had to say about red dot sights and will look to have my new prescription checked for good red focus.

I use the polarizer on the front element of my matchdot even indoors. It makes the dot brighter against the target image at a lower power setting, giving better contrast & less eye strain. Usually I don't set the filter to be too dark.

I take one of the two lens out of mine on my ultradot, this gives me the perfect contrast on sunny days and gets rid of the problem of filter turning dark from the recoil.

I use the polarizer anytime the sun is on the target. Makes it much easier to see the dot.

I used to shoot with a high master who said that he always adjusted the polarizer dark, so he could barely make out the target. It worked for him.

I have tried them years ago but quit using them. My glasses are photo grey so they automatically darken, as such I didn't see any advantage to using them.

Somewhere I've got a half dozen or so.

The polarizers don't work very well in combination with eyeglasses with polarized lenses.

I forget the dual-polarizers and use a 30mm Neutral Density Filter on my UltraDots for bright days outdoors. No surprise changes with repeated recoil and the optical quality is superior. $15 on Amazon or Ebay - designed for video cameras. I have also made my own from existing UltraDot filters by punching out the polarizing screens and cementing in cutouts from a Tiffin 4" square filter. You can even select colored filters if you desire!
