Knowing your pitch speed changes everything about how you train. It gives you a baseline to improve against, lets you track progress over weeks and months, and provides objective data that takes the guesswork out of development. Whether you are a parent clocking your kid's fastball at practice, a coach evaluating pitchers during tryouts, or a player building a training log, a radar gun turns subjective impressions into hard numbers.
Radar guns range from $30 pocket devices to $1,000+ professional units used by MLB scouts.
The good news is that you do not need the expensive end to get accurate, useful readings. Here are the best options across different price points.
How Baseball Radar Guns Work
Most consumer radar guns use the Doppler effect to measure speed. The gun emits a radio signal that bounces off the moving ball and returns to the gun at a slightly different frequency. The gun calculates the speed based on that frequency shift.
The technology is well established and, when used correctly, provides readings within one or two miles per hour of professional-grade equipment.
Accuracy depends heavily on positioning. Radar guns are most accurate when pointed directly at or directly behind the ball's path. Standing off to the side introduces a cosine error that reads lower than the actual speed. For the most accurate readings, position yourself behind the catcher looking toward the mound, or behind the pitcher looking toward the plate.
Stalker Sport 2 Radar Gun
The Stalker Sport 2 is the gold standard for baseball radar guns.
It is used by MLB scouts, college programs, and serious travel ball organizations. The gun reads pitch speed from release point or at any point along the flight path, and it can simultaneously display the peak and plate speed on a single throw. The range extends to 300 feet with accuracy within plus or minus 0.1 mph.
The Stalker Sport 2 is a professional tool with a professional price tag, typically around $1,000 to $1,200.
For that investment, you get the most trusted name in baseball speed measurement and readings that scouts and coaches will not question. If you are purchasing for a program, travel team, or training facility, the Stalker is the benchmark.
Pocket Radar Ball Coach
The Pocket Radar Ball Coach is the best option for personal use and smaller programs. It fits in your pocket, runs on two AAA batteries, and provides readings within plus or minus one mph up to 120 feet away. It is used by thousands of travel ball teams, pitching coaches, and parents who want reliable data without carrying a bulky gun.
The Ball Coach can measure speed from behind the pitcher or behind the catcher, and it picks up the ball's speed quickly without requiring precise aiming.
The trigger is simple: point, pull, and read the speed on the LCD display. It also includes a continuous mode that reads every pitch automatically, which is useful for bullpen sessions and tryouts where you do not want to trigger the gun for every throw.
At around $300 to $350, the Ball Coach is a fraction of the Stalker's price while delivering accuracy that is more than sufficient for training, evaluation, and development purposes.
This is the radar gun I recommend to most individuals and small programs.
Bushnell Velocity Speed Radar Gun
The Bushnell Velocity is the entry-level option that gives you basic pitch speed readings at the lowest cost. Shaped like a traditional point-and-shoot radar gun, the Bushnell reads speeds from 10 to 110 mph with accuracy within plus or minus one mph in ideal conditions.
It also measures the speed of vehicles, tennis serves, and other moving objects, which makes it a fun multi-use gadget.
For baseball specifically, the Bushnell works best from behind the catcher or from a position relatively close to the ball's path. At longer ranges or from wide angles, the readings become less reliable. The trigger mechanism and speed pickup are not as fast or consistent as the Pocket Radar, so you may miss some pitches in rapid succession.
At around $100 to $130, the Bushnell is the most affordable dedicated radar gun worth buying.
It is a good starting point for parents who want to see where their kid's velocity stands without a major investment. Just understand its limitations and do not compare its readings directly against more accurate equipment without accounting for potential variation.
Rapsodo Pitching Monitor
The Rapsodo Pitching Monitor is not a traditional radar gun. It is a ball-tracking device that uses a combination of radar and camera technology to measure speed, spin rate, spin axis, strike zone accuracy, and movement on every pitch. It connects to an iPad and provides detailed analytics that go far beyond simple velocity numbers.
For pitchers who are serious about development, the data from a Rapsodo unit is transformative.
You can see not just how fast you throw but how much your breaking ball actually moves, what your spin efficiency looks like, and how your pitch placement trends over a session. That level of detail helps pitchers and coaches make targeted adjustments that improve performance faster than velocity tracking alone.
The Rapsodo Pitching Monitor costs around $500 to $600 and requires an iPad with the Rapsodo app.
It is more than a radar gun purchase, but the depth of data it provides is unmatched by anything in its price range. For high school, college, and competitive travel ball pitchers, the investment pays for itself in development value.
Tips for Getting Accurate Readings
Position matters more than equipment quality. Always stand directly behind the pitcher or directly behind the catcher to minimize angle error.
Readings taken from the side will consistently read low, sometimes by five or more mph, which gives you misleading data.
Take multiple readings and look at the average rather than chasing the highest single number. Velocity fluctuates pitch to pitch, and a meaningful data point is your average fastball speed over 10 to 15 throws, not the one pitch where the gun happened to catch you at your best.
Give the pitcher time to warm up fully before recording numbers.
Cold-arm velocity is lower than warm-arm velocity, and mixing the two in your data set skews the results. Wait until the pitcher is fully loose and throwing at game effort before starting to track.
Note the conditions when you record. Temperature, fatigue, and time of day all affect velocity. A reading taken at the beginning of a fresh bullpen session is not directly comparable to one taken in the fifth inning of a game. Context makes your data meaningful instead of just a collection of numbers.
