Stop guessing if that pitch or swing was actually faster. See the number, every rep, automatically.
Pocket Radar – The Ball Coach™ is a compact Doppler radar gun designed to automatically track the fastest speed of a ball in flight so coaches and athletes see real velocity instead of throwing or hitting “by feel.” Doppler radar here means the unit sends out a signal and reads how its frequency shifts when it bounces off the moving ball, which is how it calculates accurate speed in baseball, softball, tennis, volleyball, lacrosse, hockey, and more.
- Designed to Track the Ball, Not Everything That Moves — Tuned specifically to find and display the fastest speed of a ball in flight instead of reading bats, arms, or background motion. That ball-first logic makes it easier to trust that the number on the screen is a true pitch or exit velocity, not noise.
- Automatic Triggering with Constant-On and Manual Modes — Hold the trigger down and release after the pitch or hit, or use Constant-On mode for hands-free auto-capture. Manual gives precise control in bullpens; Constant-On lets you coach, chart, or run stations without babysitting the gun.
- 25-Reading Memory for Full-Set Review — Stores the last 25 readings so you can scroll back and review a complete bullpen, exit-velo round, or velocity block — spotting trends even when the athlete “feels fine.”
- Compact, Pocket-Size Form Factor — ~4.7″ x 2.3″ x 0.8″, ~4.5 oz with batteries. Rides easily in a pocket, belt holster, or bag — move quickly between mounds, cages, and drills without hauling a full-size gun and tripod.
- Pro-Level Accuracy and Range — Measures 25 to 130 mph with ~±1 mph accuracy and up to 120 feet of range on a baseball or softball. Independent comparisons show it matching larger professional radar guns closely enough for serious training and charting work.
- Simple Interface That Keeps Focus on Coaching — A large front button activates and captures speeds; a smaller side button recalls memory, switches modes, and adjusts units. No apps or extra menus — keep your eyes on the athlete.
What Is It?
Pocket Radar – The Ball Coach™ is a handheld Doppler radar gun engineered to automatically find the fastest speed of a ball in flight and display it on a bright, built-in screen. It is purpose-built for sports where ball speed matters — pitching velocity, exit velocity off the bat, serve speed, shot speed, and similar metrics across multiple sports.
Compared with all-purpose speed guns or classic police-style radars, the Ball Coach™ is tuned for ball-tracking and sized for everyday field use, with ±1 mph accuracy and 25-reading recall in a pocket-sized housing. Compared with training by eye or feel, it replaces debates and guesswork with objective ball-speed data that either rises, holds, or drops as you change drills, cues, or implements.
How It Works
Key mechanisms behind objective velocity feedback
Strengthening the External Focus of Attention
Watching the number on the gun gives athletes an external target to chase — “beat that last velo” — instead of over-focusing internally on limb positions. Research on attentional focus in skill learning suggests this kind of external focus can speed up motor learning and help athletes self-organize more efficient movement patterns.
Revealing Mechanical Leaks Through Velocity Changes
Mechanical leaks such as opening the front side early or losing a firm lead-leg block show up immediately as drop-offs in ball speed. That cause-and-effect relationship makes velocity a simple proxy for how well the kinetic chain — the linked sequence of joints and muscles from the feet through the legs, hips, trunk, and arm — is doing its job.
Flagging Fatigue and Protecting Intent-Based Work
High-intensity velocity work only pays off when the nervous system is fresh; once ball speeds sag despite honest intent, quality is dropping. Using the gun to end a session when velocity has clearly slid helps protect mechanics, reduce junk volume, and keep “going hard” tied to actual output, not just effort.
Backed by Research
Objective Feedback for Velocity Training
Pocket Radar – The Ball Coach™ is a measurement tool, not a training implement; its value comes from pairing accurate ball-speed data with good programming so athletes and coaches can separate what feels powerful from what actually moves the ball faster. Without a radar, small changes in effort, adrenaline, or fatigue can make a slow rep feel explosive or a fast one feel routine.

How to Use It
Set up to avoid cosine error: Position directly in line with the ball’s flight path — behind the catcher or target, or in front of the hitter/thrower. Large angles create cosine error that makes readings falsely low, so “down the line” beats “off to the side.”
Choose trigger mode or Constant-On: For focused bullpens, hold the front button down before the pitch and release once speed appears. For stations or camps, use Constant-On so the radar automatically triggers while you coach or chart.
Integrate radar feedback into skill work: Establish a baseline, then introduce constraints — weighted balls, underload/overload bats, mechanical cues — and watch the numbers. Keep changes that raise velocities; discard ones that leave speed flat despite good effort.
Use memory to manage fatigue: Scroll through the last 25 readings to see whether the athlete held velocity or tapered off. A consistent 2–3 mph drop under max effort signals fatigue — often a cue to shut the drill down.
Variant & Selection Guide
| Variant | Weight | SKU | UPC |
|---|---|---|---|
| Pocket Radar – The Ball Coach™ radar | 7 oz | TBC | 608938928023 |
Single pro-level ball-speed radar model. Used for pitching, hitting, serves, shots, and more across baseball, softball, tennis, volleyball, lacrosse, hockey, and cricket.
Who This Is For
- Commonly used for baseball and softball pitchers and hitters who want accurate pitch velo and exit velo in bullpens, cages, and live sessions.
- Commonly used for coaches running velocity-development or weighted-ball programs who need simple, portable ball-speed tracking across multiple environments.
- Commonly used for multisport facilities and academies that train serve speed, shot speed, and ball exit speed across tennis, volleyball, lacrosse, hockey, and cricket.
- Commonly used for parents and athletes who want a reliable at-home velocity tool without the cost or complexity of a full launch monitor.
What This Implement Does NOT Do
- It does not measure spin rate, movement profile, launch angle, or location; it only measures the fastest ball speed in flight.
- It is not a swing-speed radar for bats or clubs; it may pick up bat or club speed in some positions, but it is optimized and marketed specifically for ball speed.
- It is not a coaching replacement; it will show you the numbers, but coaches and athletes still need to decide how to change mechanics, workload, or drills.
- It does not make velocity training risk-free; volume, rest, and throwing or hitting mechanics still have to be managed thoughtfully, especially with weighted-ball work.

Safety and Care
Not a toy — the Ball Coach™ is an electronic training device and should not be struck by balls, bats, sticks, or racquets. Always place the radar behind a screen, catcher, or target line so a miss-hit ball cannot impact the device.
- Not a toy: Electronic training device only — should not be struck by balls, bats, sticks, or racquets.
- Protect the unit: Always place behind a screen, catcher, or target line.
- Respect velocity work volume: High-intent sessions should be programmed carefully, especially for youth and in-season arms; use consistent velocity drop-offs as a cue to stop.
- Battery handling: Use only recommended AAA batteries, insert with correct polarity, and do not mix old and new or different types.
- Medical considerations: Any velocity-focused work with injured or returning athletes should be supervised by qualified medical or performance professionals.
Frequently Asked Questions
What does the Ball Coach™ measure?
It measures the fastest speed of a ball in flight — pitch velocity or ball speed off the bat, racquet, or stick — depending on how you aim it.
How accurate is it compared to big radar guns?
Rated at ±1 mph accuracy with up to 120 feet of range on a baseball, and comparison tests show it tracking closely with larger, professional baseball radar guns.
Can it be used indoors and in cages?
Yes. As long as you can aim it straight down the ball’s flight path and keep it out of the impact zone, it works well in cages, tunnels, and indoor gyms.
What’s the difference between manual and Constant-On mode?
In manual mode you hold the trigger down and release after the pitch or hit; in Constant-On mode the radar runs hands-free and automatically captures ball speeds, ideal for camps and stations.
Do I need a tripod or can I hand-hold it?
You can hand-hold it behind the catcher, behind a screen, or near a target, or mount it on a tripod (sold separately) when you want a fixed reference point.
Will it help me throw or hit harder?
The radar does not change mechanics by itself, but it makes it very clear which training blocks, cues, and constraint drills are actually increasing your ball speed and which are not.
