    Howdy! I’ve been a long time reader. The information has been very helpful and often times invaluable!

    For those that are/have used the Apollo as a standalone weapon sight, can you use the digital zoom without affecting POI?

    I’ve had mine for 4-5 years and have always used as a clip on. I decided to try it as a standalone sight this weekend to trim weight for hiking around looking for hogs, etc.

    I used the Boresight menu to adjust the recticle. Had it zeroed at 100yds on 4x. However, when I’d change magnification, my POI shifted. It would always return to zero at 4x, so I wound up shooting hogs on 4x all night - but it was frustrating having to toggle up to 4x to make the shots.

    I feel like I’m missing something, but I’m at a loss. Any help, insights, or guidance would be much appreciated!

    I've had the same experience with mine. Same setup apollo 640 as a stand alone. I can shoot accurate on 2 and 4 X. Check my previous posts for more details

    Thanks. I can’t believe I didn’t come across your post in my hours or a scouring this and other forums.

    Before I go blow through another $30-40 of ammo trying to get this thing working right. Did you wind up zeroing on 8x or at the lower 4x?

    I’ll have to play with it to verify, but it seems I was having 8-10” shift of POI when I went from 4x to 8x. Maybe the difference between 2x and 4x is small enough that it won’t matter. Which would be acceptable. 2x and 4x is ideal.

    What kills me is that when the recticle is centered before making Boresight adjustments (windage and elevation at 0), the magnification doesn’t seem to impact POI. But once I boresight the recticle is off center, so zooming pushes my recticle down and right.

    Anyway thanks for the reply dogman. This gives me hope again that it can be used as a standalone!

    Okay, got the tripod out and set an ice block down the hall way to test. Surprisingly, when I set the recticle dead center on the ice block at 1x, there is a shift of POA/POI when going to 2x.

    However, when going from to 2x to 4x there doesn’t appear to be a shift. 4x to 8x, however, there is another shift.

    I’m going to confirm this at yardage next week at the ranch with live rounds, but hopefully 2x and 4x are useable and accurate.

    I've settled in on using 2x to scan and take a quick shot and 4x when I have time to adjust. I struggled with mine for months and missed several coyotes before getting the sweet spot I can live with. The margin shift was key to getting where I'm at now. It seems the margins can be shifted and cause it to hit on one side of the target at closer ranges and the other side at distant ranges . Hope this helps

    Thanks. This helps! I’ll play with the margins to see if I can get it any closer. Last time I was out I was hitting pigs, but they were 50-60 yards away and the 4x made it difficult after they scattered.

    Didn’t get a chance to shoot at a paper target for exact precision - but did lock the gun in and confirm that there is virtually no shift between 2x and 4x - at least that my eye could detect at 100yds.

    Dropped a boar at about 115 yds Saturday night on 4x - although, I agree with you. 2x is the optimal blend of scanning capabilities and quick target acquisition. At 4x the FOV is cut down making it a little more difficult to locate your target.

    Gun is shooting good enough for now with the current setup, but when I have time I’ll play with the margins at longer ranges to see if there’s additional benefit to gain.
