Instructional DVD
If you have never blown a Silva Fox Whistle or Tenterfield style Whistle, have never whistled foxes or have only used a round Button style Whistle, we highly recommend that you purchase the Instructional DVD. To start off you will watch 15 minutes of Instruction on how and where to place the whistle in your mouth and how to blow the whistle etc how to maintain and look after your whistle followed by 25 foxes being whistled, total running time 52 minutes. We have received some very favourable comments in regards to this DVD.
This shows how effective the "Silva Fox Whistle" is, when a fox wants to take it out of your mouth. https://www.youtube.com/watch?v=QN1vtxS72CE
