Well put together video Dave. Only variation I do with the 40/50 center reticle scopes are fine tune my speed dial at 70 or 80 yds. I've found with doing that, 20 yds will still be within 1". But the further ranges are calibrated better. If fine tuning the speed dial at 20 yds, some of the further ranges can be a couple inches off, or more.
I’ve been shooting off a table and sandbags to sight in. But the method you describe sounds better…to move the crosshairs to the poi of the arrow you shot, keeping the bow in a solid rest. That’s hard to do on sandbags unless you have a helper. Is the Bog field pod that supports both the front and the rear of the bow (probably hold bow still with bungees some how) better than the Bog pod that clamps at the middle of the bow? I have not both either yet. Thanks
