I've been using Phelps products for the past five seasons. The Phelps Grey was my go to call until I stumbled across the pitch black series. The Pitch Black 2 has been my constant companion ever since. The Pitch Black 2 is easy to blow and produces all elk sounds. This call performs flawlessly while chasing Rocky Mountain elk as well as being capable of hitting the high, ringing notes required when hunting Roosevelt elk. This call does it all.
