Key Takeaways
- Communication must be one-way from coach to player.
- Players cannot speak back or transmit audio.
- Smartwatches and apps are allowed if they do not enable two-way voice.
- Umpires can inspect devices at any time.
What Is It?
NFHS (National Federation of State High School Associations) allows limited electronic communication if:
It is one-way only, and
It does not disrupt the game or give unfair advantages.
How One-way Works
Legal examples:
Coach sends pitch calls to a catcher’s smartwatch
Coach uses an app to send numeric or visual signals
Coaches talk to a catcher (one-way)
Illegal examples:
Players responding with equipment
Players wearing devices with microphones that are not disabled
Why This Matters
Avoids penalties
Keeps communication fair
Modernizes pitch calling safely
Improves pace of play
Best Practices / Recommendations
Use listen-only hardware and software
Keep the player device in the dugout for voice-only systems
Train the catcher on how to receive pitch calls
Keep the system simple and fast
