Why Speed Measurement Matters for Training
You can't improve what you can't measure. Whether you're a Little League pitcher working toward your first 50 MPH fastball, a high school softball player refining swing mechanics, or a weekend golfer chasing more distance off the tee, objective speed data reveals exactly where you stand and tracks real progress over time.
This guide covers three categories of sports speed technology: radar guns that measure ball or puck velocity, swing analyzers that attach to bats and capture swing metrics, and golf launch monitors that track club speed, ball speed, launch angle, and more. Each serves different training needs, and we'll help you find the right tool for your sport and budget.

đ Buyer's Guide: Choosing the Right Speed Sensor
Radar Guns vs. Swing Analyzers vs. Launch Monitors
Speed Radar Guns measure how fast an object is moving through space. Point it at a pitch, throw, or shot and get a velocity reading. Best for: pitchers tracking velocity, coaches evaluating players, parents wanting objective data.
Swing Analyzers attach to your bat and capture the mechanics of your swingâbat speed, attack angle, time to contact, and more. Best for: hitters who want to understand and improve their swing mechanics.
Golf Launch Monitors track the ball after impact, measuring ball speed, launch angle, spin rate, and carry distance. Many also measure club speed. Best for: golfers who want comprehensive shot data for practice and fitting.
Accuracy: How Much Does It Matter?
±1 MPH: Professional-grade accuracy. Essential for scouts, serious training, and tracking small velocity gains over time. Pocket Radar devices hit this standard.
±2-3 MPH: Training-grade accuracy. Good enough to track general progress and make practice more engaging. Most mid-range devices fall here.
±4-5+ MPH: Recreation-grade accuracy. Fine for fun and motivation, but not reliable for tracking real development. Budget devices like NetPlayz operate here.
App Connectivity: Worth the Extra Cost?
Apps add significant value if you want to track progress over weeks and months. Features like video overlay, velocity charts, and session history turn individual readings into actionable training data. If you just want a number in the moment, standalone devices work fine.
Hands-Free vs. Point-and-Shoot
Point-and-shoot radars (Bushnell Velocity, Pocket Radar) require someone to aim at the target. Great when you have a partner or coach.
Hands-free devices (Smart Partner 2.0, NetPlayz) mount on a tripod and capture everything that passes through their detection zone. Essential for solo practice.
đ« 5 Costly Mistakes to Avoid When Buying Speed Sensors
Expecting budget radars to match pro accuracy
A $50 radar will give you ballpark numbers, not the ±1 MPH precision that reveals real velocity gains. If tracking development matters, invest in Pocket Radar or similar pro-grade equipment.
Ignoring your actual use case
Radar guns measure ball speed. Swing analyzers measure bat mechanics. Launch monitors measure ball flight. They're different tools for different goals. A swing analyzer won't tell you pitch velocity, and a radar won't tell you attack angle.
Overlooking app subscription costs
Many devices offer basic functionality for free but require subscriptions for advanced features. Factor in ongoing costs when comparing total value.
Buying a golf launch monitor for baseball
Golf launch monitors are designed for golf ball flight characteristics. While some can measure other objects, they're not optimized for baseball or softball. Get sport-specific equipment.
Prioritizing features over fundamentals
A reliable, accurate device you'll actually use beats a feature-packed unit that's too complicated. Start with what you need, not what sounds impressive.
đ Quick Guide: Getting Accurate Radar Readings
Position correctly: For best accuracy, position yourself (or the radar) directly behind or in front of the target's line of travel. Angle reduces accuracy.
Optimal distance: Most personal radars work best at 20-60 feet. Too close and they may not register; too far and accuracy decreases.
Minimize interference: Other moving objects, metal structures, and electronic devices can affect readings. Test in clear environments.
Consistent conditions: For tracking progress, use the same device, position, and conditions each session.
Multiple readings: Take several readings and look at averages. One-off numbers can be misleading.
â Frequently Asked Questions
What's the most accurate radar gun under $300?
The Pocket Radar Smart Coach delivers ±1 MPH accuracyâthe same precision used by MLB organizationsâat under $300. It's the best value for serious training accuracy.
Do I need a radar gun or a swing analyzer?
They measure different things. A radar gun tells you how fast the ball is moving. A swing analyzer tells you how you're swinging the bat (speed, angle, mechanics). Pitchers typically want radar guns; hitters benefit more from swing analyzers.
Can I use a baseball radar for golf?
Technically yes for basic speed, but golf-specific launch monitors provide much more useful dataâlaunch angle, spin rate, carry distance, and club path. For serious golf training, get a golf launch monitor.
How accurate are budget radar guns?
Budget radars like the Bushnell Velocity and NetPlayz typically have ±3-5 MPH accuracy. That's fine for general fun and motivation but not reliable enough to track small velocity gains over time. Serious training requires ±1-2 MPH devices.
What's the best radar for youth baseball?
For casual youth use, the Bushnell Velocity is affordable and fun. For tracking development seriously, the Pocket Radar Smart Coach is worth the investmentâaccurate data helps coaches and parents make better training decisions.
Can I use a launch monitor indoors?
Yes, most modern launch monitors like the Garmin R10 and Rapsodo MLM2PRO work indoors. You'll need adequate ceiling height (10+ feet) and hitting into a net. Check specific product requirements for minimum space.
How much space do I need for a golf launch monitor?
Most portable launch monitors need 8-10 feet of ceiling height and about 10 feet of ball flight before hitting a net. Check your specific device requirements, as some need more or less space for accurate readings.
Are app subscriptions worth it?
If you'll use the tracking features, yes. Apps transform individual readings into progress charts, video libraries, and actionable insights. If you just want spot-checks, standalone devices without subscriptions work fine.
What's the difference between the Pocket Radar Smart Coach and Ball Coach?
Same ±1 MPH accuracy. The Smart Coach adds Bluetooth and app connectivity for tracking sessions over time. The Ball Coach is standaloneâno phone needed. Choose Smart Coach for data tracking, Ball Coach for pure simplicity.
Can radar guns work for hockey and lacrosse?
Yes. The Potent Hockey Radar 2.0 is optimized for puck speeds, and the CRANKSHOOTER is designed for lacrosse. Multi-sport radars like Pocket Radar also work, though sport-specific options may offer better ergonomics for those training scenarios.
