Coach to Catcher Communication Devices: Every Option in 2026

A coach-to-catcher communication device does one thing: it gets the pitch call from the dugout to the catcher's ear without a hand signal that a runner on second base can relay to the hitter. The call travels electronically — private, instant, unreadable.

MAVTRAX is what most youth and travel programs actually use for this. Coach taps the pitch on their phone. Catcher hears "Fastball, low and away" through a $15 Bluetooth headset under the helmet in under a second. Nothing to steal. Pitch logged automatically. 14-day free trial, no credit card. Here's how every option compares so you can pick what fits your program.

The pitch call itself is identical between MAVTRAX and PitchCom — spoken audio, private, instant. The differences are cost, analytics, and whether you need a dedicated hardware device or a phone that's already in the dugout.

The game-day flow:

1. Pre-game: Turn on the catcher's Bluetooth headset. Open MAVTRAX on the coach's phone. The headset auto-connects in under 5 seconds. Quick confirm — coach calls one test pitch, catcher hears it.
2. Each pitch: Coach taps pitch type (fastball, curve, slider, changeup, etc.) then location (inside corner, down and away, up and in, etc.). Spoken call reaches the catcher's earpiece in under a second.
3. Catcher relay: Catcher gives the pitcher a simple agreed sign — one finger down, two fingers, whatever's natural. The pitcher doesn't need to wear anything electronic.
4. Post-game: MAVTRAX logs every pitch. Open the dashboard to see pitch mix by pitcher, count tendencies, location breakdown. Share with your pitching staff or a player's parents.

PitchCom's $288 hardware kit can be configured coach-to-catcher: a bench coach wears the wrist transmitter and presses buttons to send pitch calls to the catcher's earpiece. The catcher then relays to the pitcher with a simple sign.

PitchCom's advantages in this setup: no phone on the bench, proprietary RF (not Bluetooth), and the MLB pedigree that some programs value for recruiting optics.

PitchCom's limitations: no pitch logging, no analytics, $288 per team (multiplied across multiple age groups), and a specific receiver hat the pitcher must wear. Full PitchCom explainer → · PitchCom price breakdown →

Two distinct communication problems — make sure you're solving the right one:

Coach to catcher — the dugout calls the pitch and the catcher hears it. The catcher relays to the pitcher via hand sign. This is MAVTRAX's primary use case and the most common setup at the youth and high-school level, where coaches control the game plan.

Catcher to pitcher — the catcher calls the pitch and signals the pitcher directly, either electronically or via traditional signs. This is how MLB's PitchCom was originally designed — catcher controls the transmitter, pitcher wears the receiver hat. At the college and pro level where catchers are experienced game-callers, this setup gives the catcher full authority over the sequence.

At the youth level, coach-to-catcher is almost always the right choice. The coach has the pitch count, the pitcher tendencies, and the game plan in front of them. Electronic calling lets them communicate that directly to the catcher's ear without any of it being visible to the opponent.

Most organizations permit electronic communication systems between dugout and battery. Confirm with your specific league before the season:

• USSSA Baseball/Softball: Generally permits electronic signaling. Check current rules for your age division.
• Little League / USA Baseball: Rules vary by affiliate and district. Confirm with your local district director.
• Perfect Game, NABF, AABC: Most national travel events allow electronic communication between dugout and battery.
• NFHS (high school): Provisions for electronic systems exist. State associations may restrict further — verify with your state athletic association.
• Fastpitch softball: USA Softball and most travel organizations generally permit systems. Confirm per event.

MAVTRAX is a coach-to-catcher tool. Coach sees a screen and sends the call. Only the catcher's earpiece receives it. No information reaches any other player or the batter. That structure — equivalent to a coach giving a sign, just electronic — is what leagues evaluate.

Any Bluetooth headset that fits under a catcher's helmet works with MAVTRAX. Two popular setups:

• $15 clip speaker: Mounts inside the helmet padding near the ear. Open-ear design — catcher hears the field. IPX7 sweat-resistant. Buy two; a backup unit costs nothing at this price. This is where most programs start.
• SHOKZ bone conduction (~$80): Sits on the cheekbones — ears fully open. Titanium band, 6-hour battery, Bluetooth 5.1. For programs running calls every inning, every game, all season.
