This all depends on the type of ceramic that is used.. Back several years ago you could find a ceramic that some builders used that was a darker ceramic and I feel the darker ceramic makes for a better pot call. IMO
I have one of the older ceramic pots with the darker ceramic and it goes with me on all hunts..I have some other ceramic pots that are good pots, but of those they don't compare to the older one I carry..
I have one of Busters and it's a good pot call alone with some of the others mention
