How Does PitchCom Work? (And Is There a Cheaper Way to Do It)

PitchCom is the electronic pitch-calling device used in MLB — a $288 hardware kit that sends pitch calls to an earpiece in the pitcher's hat. Here's exactly how it works, what it costs, and what youth and travel teams use instead.

Key takeaways

  • PitchCom is a $288 dedicated hardware system — transmitter, receiver hat, and earpieces. No phone, no subscription, but no analytics either.
  • Most youth and travel teams skip the hardware. MAVTRAX does the same job — silent electronic pitch calls to the catcher's ear — on a phone you already own, for $4.99/month.
  • 14-day free trial, no credit card required. Start calling pitches electronically tonight.
  • PitchCom sends the call over proprietary RF frequency (not Bluetooth). MAVTRAX sends it over standard Bluetooth to any $15 headset under the helmet.
  • PitchCom doesn't log anything. MAVTRAX logs every pitch type, location, count, and pitcher — and you can review the data after the game.
  • The decision is simple: if you want no phone on the bench ever, PitchCom's hardware wins. If you want analytics + lower cost + a phone you already have, MAVTRAX wins.

PitchCom is the electronic pitch-calling system that MLB mandated after the Astros sign-stealing scandal — a hardware transmitter worn on the wrist that sends pitch calls electronically to earpieces in the pitcher's hat. No hand signs. No sequences to steal. The call goes from input to ear in under a second.

Youth and travel coaches saw it and started asking: "Can we run this?" The honest answer: yes, but at $288 for the hardware kit with no analytics and no youth discount, most coaches find that MAVTRAX — which does the same job on a phone you already own for $4.99/month — is the smarter call for their program. Here's exactly how PitchCom works, who it makes sense for, and what most travel teams actually use.

How PitchCom works (the hardware breakdown)

PitchCom is a purpose-built, proprietary radio-frequency system with three pieces:

  • The transmitter — worn on the wrist or hand. Labeled buttons for pitch type (FB, CB, SL, CH) and location (up, down, in, away). The caller presses pitch type first, then location.
  • The receiver hat — a standard baseball cap with a small RF receiver in the brim. Picks up the signal and converts it to audio.
  • The earpieces — tiny speakers in the hat or worn separately. Play the spoken call: "Fastball, down and in." The call reaches the ear in under half a second.

The signal travels over a short-range proprietary RF frequency (not Bluetooth, not Wi-Fi) that's encrypted and can't be intercepted. Range covers any youth or high-school field easily.

What PitchCom does NOT do: it doesn't display the call on any screen, doesn't log what was called, and doesn't connect to a phone or dashboard. It's a one-way wireless signal — call goes out, call lands in an ear, that's it.

How MAVTRAX does the same thing — without the hardware

MAVTRAX replaces the dedicated RF hardware with the phone that's already in your pocket. The call flow is identical:

  1. Coach opens MAVTRAX on their phone in the dugout. No Wi-Fi or cell service needed — the call travels Bluetooth directly to the catcher's headset.
  2. Two taps: pitch type, then location. Same as PitchCom's two-button input.
  3. Catcher hears the call through a $15–$80 Bluetooth headset under their helmet in under a second. "Changeup, low and away."
  4. Nothing to steal. The call is private Bluetooth audio — no visible hand movements, no sequence to decode from third base.

The calls are just as fast, just as private, and just as clear. What changes: you're using Bluetooth and a phone instead of proprietary RF and a $288 hardware kit. And every pitch you call gets logged — you can look at the count breakdown, pitch mix by pitcher, and location tendencies after the game.

Try it tonight: Start a 14-day free trial — no credit card required. Pair any Bluetooth headset to the coach's phone. Call your first electronic pitch in under 10 minutes.

The only real argument for PitchCom's hardware over MAVTRAX: no phone on the bench. PitchCom's transmitter is a dedicated button pad — if your program has a strict no-phone culture or you personally prefer not to hold a phone during the game, that matters. For most coaches who are already using a phone for lineup management, pitch counts, and video, it's not a meaningful difference.

Who calls the pitches with PitchCom?

In MLB, three setups exist:

  • Catcher-to-pitcher: Catcher wears the transmitter, calls pitches traditionally but electronically. Keeps the catcher in charge of game-calling.
  • Coach-to-catcher: A bench coach wears the transmitter, calls the pitch, catcher hears it and relays to the pitcher. This is the most common setup for youth baseball where coaches call pitches.
  • Dugout-to-pitcher direct: Some teams go directly from the dugout to the pitcher's earpiece, cutting out the catcher relay.

MAVTRAX runs coach-to-catcher by default — the coach calls from the phone, the catcher hears it and gives the pitcher a simple agreed sign. The catcher stays involved in the relay; the electronic layer handles the coach-to-catcher step where sign-stealing is possible.

Does PitchCom work for youth baseball?

Technically yes. Practically, a few things give coaches pause:

  • Price: Same $288 whether you're 12U or D1. A 3-team travel program buying 3 kits = $864 before accessories.
  • Hat compatibility: PitchCom requires their receiver hat (or installation of the module in a compatible cap). Some youth players want to wear their team hat.
  • Earpiece fit: PitchCom was designed for adult sizing. Younger players sometimes find the earpieces uncomfortable.
  • No analytics: A 10U team running pitch development where the coach wants to see pitch mix data post-game won't get that from PitchCom.

These aren't deal-breakers — programs do run PitchCom at the youth level. They're just the reasons most youth and travel coaches look at MAVTRAX first. Try it free for 14 days — if you decide you prefer dedicated hardware, you haven't lost anything.

What headset do you need for MAVTRAX?

Any Bluetooth headset works. The most popular setups:

  • $15 clip speaker: Mounts inside the helmet near the ear. Open design — catcher hears the field. Most teams start here. IPX7 sweat-resistant. Buy two so you have a backup.
  • SHOKZ bone conduction (~$80): Sits on the cheekbones, ears completely open. Titanium band, 6-hour battery. Best for programs running calls every inning all season.

Most teams spend 20 minutes on setup — pair the headset to the coach's phone, confirm the catcher hears clearly, and start calling pitches. By game two it's faster than hand signs and the coach barely thinks about the technology.

How we pick
We're the team behind MAVTRAX — pitch-calling software used by baseball and softball teams from 9U travel ball up. We spend our days around dugouts, gear bags and tournament weekends. Picks are chosen on specs, durability for youth-sports abuse, real-world price, and owner feedback — not on who pays the highest commission. Full criteria on how we pick.
