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, and you can easily use it “no hands” which is a huge plus. I got TWO of them for $4.99 delivered. which is ridiculously good value.
I’ve been using the Fox Blaster for a couple of months now and can’t find anything to complain about. Other than a few teeth marks, and even after an accidental trip through the washing machine, it’s holding up very well.
