Key Takeways
- NFHS allows coach → player communication, but not player → coach.
- Smartwatches, apps, and devices are allowed if they don’t send information back.
- Pitch calling to catchers is legal when done one-way.
- Players cannot wear devices that allow two-way communication or feedback.
- Dugout technology is allowed for strategy, data, and video review.
Why NFHS Has One-Way Rules
The rule isn’t trying to ban technology, it’s trying to keep things fair.
NFHS wants:
equal competition
no real-time “coaching assistance” beyond what a coach can say verbally
no hidden earpieces
no instant data being fed to players
Coaches tell us:
“We just want to stay compliant and avoid any chance of a protest.”
The problem?
The rulebook language is confusing, and most coaches aren’t tech experts.
So here’s the simple breakdown.
What “One-Way Communication” Actually Means
In everyday language:
✔ One-Way Communication
Coach can send information to a player, but the player cannot send anything back.
❌ Two-Way Communication
Both coach and player can speak or send data. This is banned.
NFHS wants to avoid situations where:
catchers talk back to coaches
pitchers send signals through devices
fielders communicate with the dugout electronically
But sending a pitch call or sending defensive info TO the player is allowed — as long as the player cannot reply.
What’s Legal Under NFHS
Here are legal use cases coaches can confidently rely on:
✔ Smartwatch Pitch Calling (Coach → Catcher)
If the catcher only receives signals and cannot send anything back, it’s legal.
✔ Dugout Tablets & Laptops
Allowed for:
stats
video review
charts
scouting notes
✔ Coach-to-Coach Communication
Radios, apps, and headsets are fully allowed between coaches.
✔ Visual Signals + Digital Displays
LED boards, digital pitch cards, and printed cards are legal.
✔ Any Device That Shows Info BUT Does Not Send Info
If the device is display-only, it’s allowed.
What’s NOT Legal Under NFHS
These are the things that can get a team in trouble:
❌ Two-Way Smartwatch Messaging
Players cannot:
text back
send taps
respond
❌ Audio Devices in Ears
Players cannot wear:
earpieces
earbuds
Bluetooth receivers
Even if muted.
❌ Any System Where Player Sends Data or Feedback
Example:
Cather taps a message back
Pitcher responds via watch
Player clicks a button to talk
All illegal.
❌ Devices Strictly for In-Game Coaching Feedback
Anything that gives players real-time data beyond what coaches could say verbally is banned.
Real Examples Coaches Can Use
Here are simple scenarios that help coaches understand what’s compliant.
⚾ LEGAL:
Coach taps pitch call (fastball in, slider away) → catcher receives on smartwatch.
No response from catcher.
⚾ LEGAL:
Assistant coach sends defensive alignment to infield coach → infield coach relays verbally.
❌ NOT LEGAL:
Catcher taps back, “Timeout?” through any device.
(That’s two-way.)
❌ NOT LEGAL:
Pitcher wears earbuds to hear pitches.
(Players cannot receive audio.)
⚾ LEGAL:
Dugout uses iPad for charts, spray maps, scouting notes. (Allowed.)
Common Misunderstandings
❌ “Smartwatches are banned.”
Wrong. They’re allowed if one-way.
❌ “Coach-to-coach communication is limited.”
Nope. Coach-to-coach is unrestricted.
❌ “Using technology will get us protested.”
Only if you use two-way communication.
One-way is safe.
❌ “Players can’t wear any devices.”
Players can wear devices as long as:
they don’t communicate back
they function like a display-only tool
What Coaches Are Telling Us
Here’s the feedback we hear from baseball programs:
“We needed a way to speed up pitch calling without breaking rules.”
“Smartwatches helped us clean up communication.”
“We didn’t want anything that could get protested.”
“One-way is simple and fair”
“We just need clarity on the rules.”
This article is meant to help eliminate that confusion.

Final Thoughts
NFHS isn’t against technology, they simply want to keep competition fair.
As long as your tools follow this simple rule:
Coach → Player = OK
Player → Coach = Not OK
…you’re fully compliant.
One-way communication helps speed up the game, reduce confusion, and keep everyone on the same page, legally.
