What is PitchCom — and what does it actually do?
PitchCom is a wearable electronic pitch-calling system. A pitcher wears a wristband device; the catcher uses a button unit on the wrist or forearm to select the pitch type and location. The pitcher sees or hears the call — no hand signs, no signal-stealing risk from a runner on second.
The system became widely known after MLB's 2023 mandate to all teams following the Houston Astros sign-stealing scandal. The idea is simple and genuinely useful: remove the vulnerability of hand signs entirely. Instead of a runner relaying what he reads from the catcher to the batter, the call goes electronically, directly from catcher to pitcher. No interception possible.
What PitchCom does at the MLB level:
- Catcher inputs pitch type + location via buttons on a wristband
- Pitcher receives the call on a receiver unit (wristband or earpiece)
- Call is instantaneous and private — can't be picked up or relayed by the other team
- Eliminates hand signs as a sign-stealing vector
The core benefit — instant, private, location-specific pitch calls — is the same thing MAVTRAX does, from the opposite direction. Instead of catcher-to-pitcher, MAVTRAX goes coach-to-catcher. Instead of proprietary hardware, it runs on any phone and any Bluetooth headset.
How much does a pitch-calling system actually cost?
This is where the conversation gets practical for most coaches and families.
| System type | Upfront cost | Ongoing cost | Headset |
|---|---|---|---|
| Proprietary hardware (MLB-style) | $999 starter kit; $500 per add-on receiver | None (hardware) or battery/replacement costs | Included proprietary unit |
| Wristband pitch cards | $15–$40 per set | Lamination, annual refresh | N/A |
| MAVTRAX (app-based) | $0 hardware | $4.99/mo or $49.99/yr | Any Bluetooth headset (~$15–$100) |
For most youth and travel programs, the cost equation is obvious. A hardware system at $999 for the starter kit, with every extra receiver another $500, is a significant program investment. A $4.99/mo app that runs on the coach's existing phone requires no capital purchase at all, and the Bluetooth headset a catcher needs is available for $15–$20 on Amazon.
How MAVTRAX works as a pitch-calling system
The flow is coach-to-catcher instead of catcher-to-pitcher, which is how most youth and travel systems actually work — the coach is the one calling the game, not the catcher relaying a system to the pitcher:
- Coach opens MAVTRAX on their phone in the dugout. No Wi-Fi or cell signal needed — the pitch call goes over Bluetooth directly to the catcher's headset.
- Coach taps the pitch type — fastball, curveball, slider, changeup, cutter, sinker; or for softball: rise ball, drop ball, screwball, changeup, curveball, and more.
- Coach taps the location — a 9-zone strike-zone grid (up-and-in, down-and-away, middle-middle, etc.).
- Catcher hears the full call instantly — spoken aloud in their earpiece: "Fastball, down and away." They relay to the pitcher with a simple sign or verbal "go."
- No stolen signs. The call goes directly from the coach's phone to the catcher's ear. There's nothing for a runner on second to read.
The whole flow is under two seconds. Pitchers say it actually speeds up the game because there's no back-and-forth sign shake-off — when the catcher gets the call from the coach, they know what's coming and the pitcher trusts it.
MAVTRAX vs. PitchCom: a direct comparison
| PitchCom (hardware) | MAVTRAX (app) | |
|---|---|---|
| What you buy | Dedicated transmitter + receivers | App only — phone you already own |
| Headset / receiver | Proprietary wristband or earpiece unit | Any Bluetooth headset from ~$15 |
| Cost to get started | $999 starter kit, $500 per add-on receiver | $0 hardware · $4.99/mo |
| Direction of call | Catcher → Pitcher | Coach → Catcher (catcher relays) |
| Pitch + exact location | Yes | Yes — 9-zone grid |
| Can't be stolen by runners | Yes | Yes |
| Baseball & softball | Primarily baseball | Both — full softball arsenal included |
| Works without Wi-Fi | Yes | Yes — Bluetooth only |
| Built for 9U–HS budgets | No | Yes |
| Free trial | No | 14-day free trial, no card required |
The hardware direction difference matters: PitchCom is catcher-to-pitcher (the catcher inputs, the pitcher receives), while MAVTRAX is coach-to-catcher (the coach calls the game from the dugout and the catcher hears it). For youth and travel ball, coach-to-catcher is generally the right model anyway — at these levels, the coach is driving the game-calling, not the catcher independently running a scouting-based system the way an MLB catcher does.
Other pitch-calling options: a full landscape
MAVTRAX
App-based, coach-to-catcher, any Bluetooth headset, $4.99/mo. Built specifically for 9U through high school — baseball and softball.
PitchCom
Proprietary wristband transmitter + receiver unit. Purpose-built for professional and high-level amateur play. Catcher-to-pitcher direction. Hardware purchase required.
Wristband pitch cards
Laminated card systems (4-digit or coded) where the catcher reads a number off the catcher's wrist band. No electronics, $15–$40/set, but sign-stealable if a runner reads the sequence.
Hand signs
The classic: one finger fastball, two curveball. Simple, zero cost, zero battery. But stealable by a runner on second — the problem PitchCom, MAVTRAX, and pitch cards all solve.
Is electronic pitch calling legal in youth baseball?
Most youth and travel organizations permit electronic pitch-calling systems, but rules vary by organization and level. Here's the general landscape as of 2026:
- USSSA Baseball: Generally permits electronic signaling systems within their rules. Check current USSSA baseball playing rules for your age division.
- USA Baseball (Little League, Babe Ruth, etc.): Rules vary by affiliate and level. Many districts now allow app-based systems; confirm with your local district.
- Perfect Game, NABF, AABC: Most national travel organizations allow electronic communication between dugout and battery — confirm with your specific tournament director.
- NFHS (high school): The National Federation adopted provisions for electronic pitch-calling and communication systems. State associations may add restrictions; verify with your state athletic association.
- NJCAA / college: NCAA and NJCAA have specific provisions for electronic systems; many have adopted PitchCom-style systems at the D1 and D2 levels.
What headset do you need for MAVTRAX?
MAVTRAX works with any standard Bluetooth headset — no proprietary equipment purchase required. The catcher just needs something small enough to fit under their helmet and protective gear. Here are the most common configurations:
- Low-profile clip-on speaker ($15–$20): A small Bluetooth clip speaker that attaches to the helmet strap or sits inside the helmet. No ear canal required — the speaker sits near the ear and the call comes through clearly. This is the most popular choice because nothing goes in the catcher's ear.
- Bone-conduction headset ($70–$130): Sits on the cheekbone, transmits sound through bone rather than through the ear canal. Keeps the ear open for normal sound. Works well but costs more.
- Small Bluetooth earbud ($20–$60): Any small wireless earbud fits under most catchers' helmets. Works well; preference over in-ear vs. clip is mostly personal.

Who MAVTRAX is for
MAVTRAX is built for the team that wants the electronic pitch-calling advantage — the speed, the sign-stealing protection, the coach-directed sequencing — without the hardware investment and logistics of a proprietary system:
- Youth baseball 9U–14U: Simple coach-to-catcher flow. The coach calls the game; the catcher hears the pitch and location and relays to the pitcher with a sign. Catchers love it because they're no longer guessing what the coach wants.
- Travel and select baseball: The competitive edge matters here. MAVTRAX lets a coach sequence pitches strategically — working the count, changing eye levels, setting up a swing — without fumbling with hand signs or wristband cards in a loud tournament environment.
- Fastpitch softball 10U–college: Full softball arsenal. MAVTRAX includes rise ball, drop ball, drop curve, screwball, changeup, fastball, and curveball. Both men's and women's voices available. The 9-zone location grid works for the softball plate.
- High school and independent league: Many HS coaches run a more complex system — MAVTRAX can be set to call specific sequences and locations the pitcher is most likely to execute, which turns the tool into both a communication and a game-planning asset.

Is MAVTRAX a PitchCom alternative?
Yes. MAVTRAX does what PitchCom does — instant, private, location-specific pitch calls — but it's software, not hardware. It runs on any phone and pairs with any Bluetooth headset. The direction is different: MAVTRAX goes coach-to-catcher (the coach calls the game from the dugout) rather than catcher-to-pitcher. MAVTRAX is not affiliated with or endorsed by PitchCom.
How much does PitchCom cost?
PitchCom's professional hardware system is priced for MLB organizations and comes as a proprietary wristband transmitter and receiver set. The cost makes it a significant per-unit investment for most youth programs. MAVTRAX is $4.99/month or $49.99/year with a 14-day free trial, and works with any Bluetooth headset you already own.
Can you use PitchCom in youth baseball?
PitchCom was designed for professional and high-level amateur play. The hardware cost is a barrier for most youth programs. App-based alternatives like MAVTRAX are built specifically for 9U through high school — the technology is the same but the price point is designed for real families and youth programs.
Does MAVTRAX require Wi-Fi or cell service during games?
No. Pitch calls go over Bluetooth directly from the coach's phone to the catcher's headset. No internet connection is needed once the app is loaded. This means MAVTRAX works in any ballpark — including fields with no cell service — as long as the coach's phone and the catcher's headset are within Bluetooth range (typically 30–100 feet).
What Bluetooth headsets work with MAVTRAX?
Any standard Bluetooth headset — no proprietary receiver required. Small clip-on speakers, bone-conduction headsets, and low-profile earbuds all work under a catcher's helmet. We've tested options from $15 to $130 and recommend starting with a low-profile clip speaker for youth catchers. See our full guide to the best Bluetooth headsets for catchers.
Does MAVTRAX work for fastpitch softball?
Yes. MAVTRAX includes a complete fastpitch softball arsenal: rise ball, drop ball, drop curve, screwball, changeup, fastball, curveball, and more. Both men's and women's voices are available. It works for softball from 10U through high school and college.
Is electronic pitch calling legal in youth leagues?
Most youth and travel leagues permit electronic pitch-calling systems, but check with your specific organization before the season. USSSA, Perfect Game, and most NFHS state associations now have provisions for electronic systems. Confirm with your league director — the MAVTRAX coach-to-catcher flow is typically classified the same as electronic wristband systems, which are widely permitted.
How does MAVTRAX compare to wristband pitch cards?
Wristband cards are cheaper up front ($15–$40/set) but require the runner on second to be unable to read the code. A team that figures out your wristband sequence can tip pitches. MAVTRAX is fully electronic — the call goes directly to the catcher's ear with nothing visible to read. It also lets a coach call pitch location (not just pitch type), and doesn't require the catcher to look at their wrist or count down a sequence.
Can MAVTRAX track pitch analytics?
Yes. Every pitch called through MAVTRAX is logged — pitch type, location, game, and count. The in-app dashboard shows pitch mix by game, count tendencies, and per-pitcher sequencing data. Coaches use it to review game plans and track what worked against specific hitters or lineups.
