Bob, when you're looking to purchase a custom caller it is best to contact the call maker, let them know what it is you are looking for. Any true custom call maker will talk with you and personalize the call to your needs. The problem most folks have is that they know what it is they want but have noone to tell it to, as it would be gruesome trying to talk to the CNC machine at Primos or Zink, not to mention what folks would think if they saw you talking to a machine....lol...Any of the callmakers that make pot calls on this site will definately be happy to meet your needs. Do a search on pot calls on the search engine and you'll see a pile of fellows and their comments on the call they got and who they got it from and how they like it. The end result is gonna surprise you, especially when you call in that next bird using one super hot fantastic pot call made by.................
