The 100 percent swirl acrylic makes this squaller the most gorgeous on the market, and each call has its own unique look. Precision milled on CNC, and hand buffed to bring out color and luster. Double Rubber o-rings keep the call together during extreme conditions, but you can easily remove to change your reeds when needed. Extra-large sound chamber on the top half and twice the “speaker” on the bottom half. Has more volume than most two reed squallers. Colors: Black, Orange, Yellow, Hunter Green, Red, Blue, or Hot Neon Red.
