Pro Series LabRadar Aiming Sight: Worth It?

If you run a LabRadar chronograph, you already know its one real weak point: the stock aiming groove. It’s shallow, it’s easy to misjudge, and a slightly off angle means the unit misses your shot entirely or hands you a garbage reading. The Pro Series aiming sight is a small aftermarket accessory built specifically to fix that.

To be clear on the name: this isn’t a rifle sight or anything that goes on your gun. It’s an aiming bar that bolts onto the LabRadar unit itself, replacing the factory groove with something you can actually line up with confidence.

“Here’s another piece of equipment that is a must-have for those who own the Labradar chronograph. No more getting false readings due to the fact that you did not have your Labradar properly aligned to the target.” – Scott Austin

What It Actually Fixes

LabRadar is one of the better chronographs on the market for capturing a full velocity curve, not just a single muzzle number. Yep, the Garmin is the latest-greatest, but the LabRadar is still good. But it can only do that if it’s aimed correctly at the target, and the stock groove doesn’t give you much to work with — it’s easy to be off by a few degrees without realizing it until you check your data and see gaps or garbage readings.

The Pro Series sight solves this with a proper aiming bar instead of a shallow groove. You get a clearer, more repeatable reference point every time you set the unit up, which matters most when you’re chronographing a long string of shots and don’t want to babysit alignment on every single one.

Installation

It’s a straightforward swap: remove the factory bolt underneath the existing groove, slide the new sight into place, and secure it with the included longer bolt. It sits flush and doesn’t add meaningful bulk. Once it’s on, it stays on — this isn’t something you’ll be swapping in and out session to session.

Is It Worth Adding?

If you already own a LabRadar and you’ve fought with the stock aiming groove, this is a cheap, practical fix for a real annoyance — not a gimmick accessory. If you’re new to LabRadar and haven’t run into the alignment issue yet, you may not need it right away, but it’s worth knowing this exists once you do.
