I use two kisser buttons for triangulation. I have no problem shooting tight groups at 30-40 yards. Fast getting on target and great in low-light (being peepless).

I do not know why I ever hunted using a peep sight, years past. I guess it was my fad days or succumbing to the propaganda that you cannot shoot as accurately without a peep as you can with one. I should have stopped and thought about the fact that I was already shooting very tight groups at 20-30 yards without a peep, without a kisser, and without a sight.

I shoot with both eyes open. Doing so allows me to have better depth-perception (height and yardage estimation); and to see all of what is front of me, not what can only be seen by one eye looking through a small hole.

In the end, the preference is an individual thing. However, if you allow yourself to be convinced that you cannot acquire excellent hunting accuracy without a peep, you won' t.
