During the development phase, I got to see a demo with Jerry at our grounds. I have to admit I was skeptical before I saw it. But this duck cannon is awesome. Very simple design, meaning it should be very reliable. I was amazed at how consist the launches were relative to distance, height, etc. And the launch pressure adjustment was virtually infinite but staple once set - meaning you can put the bird where you want it, time after time. Reloading is as simple as dropping the bird (of virtually any variety), bumper, foam bird, etc. in the tube. No .22 loads, no explosive gas, just a std C02 tank & you're ready to train with Tritronics or Dogtra controls. Compared to training with BBs or wingers, this launcher can cut training time considerably & you can use birds - no substitute for birds. I was very impressed.
