Why we brought radar to an indoor facility

Indoor practice is where habits get built—because you’re repeating the same reps over and over. But it’s also where speed readings can get weird if your setup isn’t right. We wanted to answer: Can a handheld radar gun stay reliable indoors? and what’s the easiest setup for coaches and parents?

The setup that gave us the most consistent readings

We tested during a normal practice—so we had pitchers throwing, hitters taking reps, and the usual indoor noise. The secret wasn’t “the fanciest radar.” It was doing three boring things correctly:

What we used


Indoor accuracy pitfalls we ran into (and fixed)

Once the setup was right, the consistent takeaway was this: you don’t need ten features. You need dependable reads and a process for using them.


Where swing sensors helped more than radar

Radar tells you outcome (ball speed). Swing sensors tell you cause (mechanics). On hitting days, the swing sensor was the better coaching tool: we could cue one change, then confirm it moved the metric in the right direction.

Radar was the best motivation tool for pitchers—especially when we tied numbers to recovery, warm-up quality, and repeatable mechanics.

FAQ

Do radar guns work indoors?

Yes, but setup matters more. Keep the radar aligned with ball flight and avoid side angles for best accuracy.

Why are my readings lower than expected indoors?

Most often it’s angle error—standing off to the side. Move closer to the line of flight or mount the radar behind the target line.

Is a hands-free radar worth it?

If you run solo sessions or want audio callouts without checking a screen, hands-free options can be a big upgrade.

Should I buy a radar gun or a swing sensor first?

Pitchers benefit most from radar (velocity). Hitters benefit most from swing sensors (mechanics).

How do I stop players from chasing numbers?

Use averages and trend lines, not single max readings. Tie numbers to repeatable mechanics and recovery.

Do I need an app?

Apps are useful for logging and video overlays, but a reliable standalone radar can still be excellent for simple training.
