yukon photon xt 6.5x50 problem

[kaduflyer]

Hi ive just got hold of a yukon photon xt 6.5x50 it has a doubler fitted problem is in daylight with cover with small hole in when viewing theres a small white spot visable on screen when turn it to darker room its fine no probs any idea what the cause is thanks 
also if i was to make it into extreme type what is the equipment i would need ie best camera lense to fit straight on to main body and does extreme have any benefits

The small hole let’s through a small amount of light, that’s what you’re seeing hence why it disappears when it’s dark. From personal experience I’d stick with a doubler over an extreme as it’s a different can of worms altogether.

Again, stick with the doubler and lift the lens cap, or at the very least push out the centre to give you a larger aperture.

You'll find zero shift if you use the small pin hole ( due to possible off centre image on lens ) and then lift the lens cap at night.

I've found the doubler ( no lens cap ) gives greater clarity over the standard xt photon.

For daylight use i just turn down the image brightness, though you can get flickering if a bright day.

From what I`ve heard using a doubler or any other modification voids the three year warranty ,no surprise really.
