Harlan builds on the fundamentals presented in the singles DVD by explaining what changes need to be made to your game while moving back on the handicap line. The second half of the DVD covers the exciting game of doubles trap. This is a much faster game, but with Harlan's help and instruction you will find the game much easier. The hold points are different in doubles, but the EYE-Cam will help you understand the differences and how to move to the second target. Harlan's DVDs are the only trap shooting instructional presentations on the market today that uses the EYE-Cam. You will find that the old saying, "one picture is worth a thousand words" is never  more true. Just imagine having one of the top trap shooters and instructors in the world telling you how he shoots and at the same time seeing exactly what he is seeing as he shoots.
