The Fox Blaster whistle sells for about 1/4 the price of another very similar brand name fox whistle. The Fox Blaster has GUFO stamped in the plastic, and is otherwise pretty much identical to the more expensive whistle. Unlike Tenterfield style fox whistles, there is absolutely no skill or learning curve required to get these plastic whistles to work. I got TWO of them for $4.99 delivered. which is ridiculously good value.
