New to the forum so hopefully got this article right.Ref DFA75
Agree with most of what Eddie has said , unit is VERY tight on the baynot mounting and it can present a bit of a fight on removal and fitting and I had the same Icon viewing problem on my FAC Daystate fitted with Meopta scope 6x42 fixed power, but moved the insert split position to the opposite side as the clamping device and that sorted it. Lack of dust cap on lens to scope seems to be a bit tight fisted and one of my battery carriers is faulty but I am sure the supplier will sort that just one of those things . Must say I thought the IR was a big improvement on the one that comes with N550 which we use as well along side a Yukon Ranger night vision device but we have fitted the Yukon with an extra IR device, all this night vision kit benefits greatly from quality IR being added.
Our DFA unit arrived and we mounted it straight away onto my riflemans Tikka .223 proceded to our foxing barn , charlie arrived in due course one shot 90m , distance is accurate, bang on target so it seems the no zeroing needed claim is correct, however different story when mounting it onto my Daystate as mentioned above so see below how we sorted it .
DFA SET UP
Following page 10 on how to adjust POI just could not make it work, as 40m was way out L/R and vertically.
To adjust POI do the following from page 10 in the manual.
Stage one follow this to gain access to what Pulsar call the limiting frame (orange box with x in it ). Instead of moving this to correspond with scope reticle I moved it to clear area in top right quadrant of scope view .
Move to stage two and some cooridnates will appear mine where X=19 Y=01, these if you have not fiddled already will
be the factory settings write them down for future ref.
Note each icon Y or X has two lots of numbers. X has 0 to 40 and 0 to -40 Y has 0 to 50 and 0 to -50.
I worked out the following and got what I wanted in the way of POI.
X moves the L/R POI and by moving into the lower numbers ie from say the factory setting X=19 to X= -15 I got the correct POI L/R so lowering the number moves POI right, moving up the numbers moves it back left.
Y works the same , lower the number ie factory setting of Y=01 move to Y= -02 and POI moves up, again move it up the numbers and POI will move down .
When you are happy with POI take note of the coordinates rifle etc and you have a record all you have to do in the future is just dial them in rifle to rifle, like all things bit of practice and get familar with it and I think the DFA really will catch on bound to be some teething problems.
All this was learnt today and don`t hold me resposible if you lose your zero or something else goe`s wrong , remember to make sure of your backdrop before attempting any zero as you may be way way off target as my Air Ranger was. I am no specialist just a shooting man so hope this may help some of you and if you have a question I will try to answer it , hopefully out with the DFA next week fitted back on the .223, must dial in the factory numbers !
