For me I wondered why we would need this, after learning with Pip and already completing IA, D&D, DNA3 and instructors for basic & advanced. However, after completing it last week I was amazed at how good it was, it breaks down an easy flow of questioning and gets you thinking outside the box for other ways to dig. It is essential as a practitioner and teacher. You will be suprised at how much it sharpens your technique or gives you great reminders you may have forgotten ????
So go on, book it!!
