How many of you have purchased the H.S. Ringzone line of calls, and what did you think? I've played a few on the demo shelves...impressive sound quality, and I'll probably buy the ceramic one anyhow....Any of you kill off one last year? The science of it (oscilloscope comparison) seems sound enough. Did anyone notice improved bird responses over your other friction calls?

Think you can do much better with custom calls.
