The Archer’s Diagnostic
Why Are My Arrows Doing That?
A Practical Troubleshooting Guide for Traditional and Thumb Draw Archers
Your arrows are trying to tell you something.
When they consistently fly left, drift right, hit high or low, fishtail through the air, or suddenly stop grouping, the worst thing you can do is begin changing everything at once.
Your grip. Your anchor. Your release. Your point of aim. Your arrows.
Before long, you have changed so many variables that you no longer know what caused the original problem.
The Archer’s Diagnostic teaches you a better approach:
Observe. Isolate. Test. Correct.
Instead of chasing individual arrows around the target, you will learn how to recognize patterns, identify the most likely causes, and test one variable at a time.
This concise 15-page field guide will help you diagnose:
- Arrows consistently hitting left
- Arrows consistently hitting right
- High and low impacts
- Groups that begin tight and then open
- Arrows kicking or fishtailing in flight
- Accuracy deteriorating after 20 or more arrows
- Shooting well up close but struggling at longer distances
For each problem, the guide explains:
- The most likely causes
- What the problem looks like
- How to test each possible cause
- Which correction drill to use
- When to examine your equipment instead of changing your form
Correct the Cause—not Just the Miss
A tight group in the wrong place is different from arrows scattered across the target.
A form problem is different from an arrow-spine problem.
Fatigue is different from equipment failure.
Until you understand the difference, every correction is simply a guess.
The Archer’s Diagnostic gives you a repeatable process for determining what is actually happening before you attempt to fix it.
Correction Drills Included
The guide includes practical instructions for:
- Blank-bale shooting
- Torba training
- Shot-cycle pauses
- Follow-through freezes
- Draw-length testing
- Video form analysis
You will also receive a one-page Quick Diagnostic that can be printed or saved to your phone for use at the range.

Who Is This Guide For?
This field guide is designed for traditional and thumb draw archers who:
- Cannot determine why their arrows keep missing in the same direction
- Struggle with inconsistent groups
- Want to diagnose their own shooting more effectively
- Need practical corrections instead of vague advice
- Want a quick reference they can carry to the range
While the directional examples are primarily written for right-handed thumb draw archers, the diagnostic principles and correction drills can be applied to other traditional shooting systems.

Frequently Asked Questions
Is this a complete thumb draw instruction manual?
No. This guide is specifically designed to help you diagnose common accuracy and arrow-flight problems. For complete thumb draw instruction, equipment selection, shooting mechanics, drills, and training plans, see The Thumb Draw Codex, Second Edition.
Is this only for thumb draw archers?
The guide was created from the Odinson thumb draw system, but many of its lessons—including fatigue, back tension, draw consistency, release problems, elevation control, and equipment inspection—also apply to other traditional archery styles.
Can I print the guide?
Yes. Your purchase allows you to save the PDF on your devices and print one copy for your personal use.
Will this tell me exactly which arrow spine to buy?
The guide helps you recognize when spine may be contributing to a problem and shows you how to test that possibility. Exact arrow selection still depends on your bow, draw weight, draw length, arrow length, point weight, and shooting method. Typical arrow spine recommendations depending on your bow can be found in The Thumb Draw Codex
How will I receive it?
