I have one bow set up with a peep and another set up with an Anchor Sight. When I pull back on either bow I automatically calibrate my anchor systems to make sure I'm lined up then look at the sight.
When I'm shooting the bow with the Anchor Sight, first get lined up then just look at the sight and deer, don't look back at the Anchor Sight, this is where I had my issues! Everybody's different so this may not be for you.
As for low light shooting, I've had major problems shooting a peep, especially with the sun in my eyes! I got the Anchor Sight to work on my HHA Slider, but I had to tinker with it!
The other nice thing about the Anchor Sight is it glows in low light, I like shooting with both eyes open and you can keep track of your animal better just before you shoot!
When setting up the Anchor sight be prepared to tinker with it till you get it right, try to get it as close to your aperture as possible.
