Thompson Target Technology includes detailed instructions on each Trouble Shooter target to make it easy to learn the correct way to apply the disciplines of shooting: body position, grip, breath control, sight alignment, trigger squeeze and follow-through.

Each diagram illustrates shot placement of both left- and right-handed shooters for ease in discerning potential problems. By following the instructions, you can evaluate your shot placement by comparing your groupings with the diagrams of eight common shooting-trouble examples.

Each diagram is accompanied by an explanation and the corrective action needed to center groupings accurately. Trouble Shooter targets come in a variety of sizes and packs. Price: from $3.89. Contact Thompson Target, 330/484-6480, www.thompsontarget.com.
