I use the P.S. Olt box and the Olt scratch box . They do right well anyone else use them?
Ive got an old PS olt Red tail hawk. Had it for many years. Love it.
I have an Olt crow call .It's the best crow call I've ever heard.
I forgot about the crow call I have one of those also. I like it OK but went to the Faulk long time back. Late in the season the little scratch will get responses when nothing else is working , I don't kow if it is because they probably haven' t been hit with it or , if the vibrations tick them off. But it has worked many times.
I have a really old adjustable reed duck call from them but I've never tried any of the turkey calls. Been tempted to bid on some that I've seen on ebay.
I have two of the old model A-50 goose calls. I have had to replace the reeds but the calls are still the best goose calls I have. The sound has probably changed over the years as I have replaced the reeds with some of my homemade ones. Still a great call. Used one for many years while hunting in the Horseshoe Lake area of southern Illinois.
A lot of guides in Arkansas still blow those for ducks, pretty good calls IMO
