It should not affect your zero.

You are basically just viewing what comes through your occular lens with a camera that can see at lower wavelengths than the human eye.

Any "ADD ON" n/v system, weather it by tubed or digital, it will be the same zero as in the day light, what will alter is the parrallax setting this will need to be adjusted a lot more to get your focus clear at different ranges, it will also be at a lower yard-age at night, a tipical 100yds at night will be around a 20 yd parrallax setting.

Even my new zoom camera that goes into the EDNV does not make any difference on accuracy or holding Zero!

Kind regards Splatty

When you fit the add on remember to check your zero and adjust as necessary. The camera may sit in a slightly different position to where you place your eye.

It makes no difference unless you hold the rifle in some bizarre way when zeroing it.

What can effect the poi is if you mount on the adjustment part of the eye bell as some have found that some droop a little, mount on the scope and theres no problem.

I shoot off the 4WD door mirror bracket and was field testing a new add-on rig this morning. I couldn't steer the car enough because of a sand pit to keep track of a nervous bunny this morning as it kept moving left towards a hedge and stopping. Long story short the greenkeeper wants the hole digging stopped so I manouvered the rifle round the door pillar and shot it whilst looking at the 5" screen from about a 30 degree angle rather than leave it for another day.

It was one of those times I wish I'd had a recorder behind me showing what I did because it was a perfect 90 yard headshot. I should point out that the monitor is located ahead of the turrets and that would not have been as doo-able if it were much further back.

The p.o.i of my .30-06 is an intended +4cm @100 m without e700 add on and +6cm @100m with e700 add on, probably due to added weight to the scope and different recoil forces due to different handling. I don't believe the line of sight through the scope is influenced by the add on.

Hi Guys,
I realize this is a late posting, but I just did a DIY build and this is the thread that fit my situation.
Basically, the pellet flies about 1" high-right off center at about 2:00.
When I took the camera off the scope and shot using just the scope optics, I get my usual group of about .25" @ 10 yards all on the "X".
So this camera setup is off somehow.
Any ideas what might be the problem?
I'm using a pump .17 cal Crossman, and it's purpose is 'ratting'.
Thanx ... Chris
