Nice Calls! I have been using them for years, and I have a Plastic Pot double Glass, that is the last resort, on stubbern birds. This plastic pot has been the cause of many a bird shedding some blood in the spring woods.Use to be owned by David Tillburg, who is a long time friend, and the company was called Tillburg Outdoor Products, before he sold the business.
Even though this is a plastic pot, I would not let this one go for any amount of money! It's that good, and Gobbs just eat it till it's gone!
