What, you ask, is KRD??? It stands for 'Key Relationship Drill', and it's a drill I read about in Evan Graham's book 'Secret of the Pros' while vacationing in early August. I did the drill several times (5 or 6) on land in August. It consists of one mark and several blinds set up in key relationships to that mark, including a blind that is tight behind the gunner (left orange line in upper photo), another that is well outside the arc of the fall (where the mark lands) (right-most orange line in bottom photo), another between the fall and the outside-the-arc blind (left orange line in bottom photo), and finally one under the arc made by the throw of the mark (right orange line in top photo).
The photos show the set up. The white blob was a stick man (white shirt on a hanger on a post) from which I threw the mark, and the mark landed about in the middle of the channel. For explanation purposes, I am numbering the blinds 1-4, left to right (the orange lines). I actually had white stakes at blinds 1 & 3, and my orange-noodled stakes at 2 & 4. After the dog retrieved the mark, I ran the blind behind the gunner 1st (blind 1). Both dogs have done blind 2 before a couple of times, most recently on Tuesday morning, which means they both were thinking about that blind when I wanted them to do both 1 and 3. We did blind 4 (right most one) next. Both of the dogs kept thinking about blind 2. I did blind 3 and then 2 with Gryffin, then repeated them 1, 4, 3. Before I did the drill with Ty, I had her do blind 3 from the left shore first. Though she didn't take an especially great initial line, at least she got in the water and started to swim. I then had her retrieve the mark, and then did the blinds 1, 4, 3, 2. When I reran 1, after first heading towards 2, I think it took only 1 or 2 casts, and then she was on the right line. Interestingly, Gryff wasn't quite so easy on his reruns. Ty had more trouble rerunning 4, but 3 was quite good. I really wanted to redo 2, but ran out of time and had to leave.
I will probably go back and do a similar set up tomorrow, but with the mark thrown from the other shore, right to left.
