DAS makes a Trad sight called the SRF Hunting Sight. It's sold by 3 Rivers (

This is not a pin sight, but a "sight picture" sight. When I got back into recurves a few years agoI tried it and found it to be KISS simple and extremely effective. More so, it was an extremely effective tool to teach sight picture at various distances. Eventually I found it had trained me to the point I was as good without it as I was with it.
Still, if I had an SRF Sight on each of my recurves I would be 100% confident that after a lay off I could pick each individual bow up and lay them in there like as if I had practiced regularly with it. It's that good...
When my son (career Army) wanted to try Trad a couple years ago, I sent him down a CM H1 with the SRF sight on it, arrows, and all the doodads needed to get started...
BTW Arwin, a big part of the reason I went back to Trad was age related near vision issues. My distance vision is superb (thanks to Lasik!) but my near vision is to the point where I can't see open sights on guns or pin sights on bows well enough to shoot them anymore...
