Inertial Trigger is a Great, Low-Cost Upgrade for LabRadars

LabRadar chronograph to register bullet speed JKL inertial trigger recoil activated

SUMMARY: This article reviews a device that “triggers” the LabRadar chronograph to register bullet speed. Rather than activate by sound or Doppler reading, this $35 JKL Inertial Trigger works from the rifle’s instantaneous recoil pulse when a shot is fired. After some frustration with his LabRadar when shooting at a range with reflective surfaces, our tester is now reporting that 100% of his actual shots are being captured correctly by his LabRadar chrono equipped with the JKL Inertial Trigger. He won’t use his LabRadar without it now. Other users have become instant fans of this inertial LabRadar trigger as well. It is very affordable and it works great. VIEW LARGE PHOTO.

JKL Inertial Trigger for LabRadar Chronograph

Product Review by F Class John
The LabRadar chronograph has been one of the most revolutionary tools in the shooting world because of how it collects velocity data, how it reports (and stores) that data, and, ultimately, the ease with which it can be positioned and operated. However, it’s not a perfect system. A majority of the complaints come from users whose LabRadars sometimes fail to record all the shots fired in a string. For the average plinker, this may not be an issue. But for serious shooters trying to do ladder tests or load development requiring all shots to be reported, it can be frustrating when a shot is missed.

LabRadar chronograph to register bullet speed JKL inertial trigger recoil activated

Traditionally, LabRadar has recommended trying different settings that compensate for the gap between the unit and muzzle as well as well as having different options for how the unit recognizes a shot fired. While these options work to some degree, they aren’t a guaranteed fix especially when shooting at ranges with concrete baffles or with roofs, walls, and dividers that can alter sound waves. While nobody can precisely explain why shots are lost under certain circumstances, the fact remains it DOES happen. In addition, the default system can sometimes pick up stray shots from nearby rifles.

Not willing to give up on this sophisticated chronograph, many shooters have looked for a foolproof way to prevent such failures from happening. In fact, for this shooter, the frustration was so high that I actually sold my first LabRadar and went back to another chronograph before ultimately buying another LabRadar almost a year later. But I made that repeat purchase only after vowing to finding a way to make the LabRadar work — EVERY time, for EVERY shot.

JKL Inertial Trigger — Outstanding Product That Works Great
Enter the JKL Gen 2 Trigger for the LabRadar. This is an easy-to-use, inertial-driven trigger that activates simply from the recoil of your gun. The unit consists of a small rectangular pad attached to a long audio cable. All you do is plug in the audio cable, attach the pad to your gun with the provided hook and loop (Velcro) material. Then (important), you must change the LabRadar trigger settings from “Doppler” to “Trigger”. The unit works great and is easy to set up. In my experience, the unit will activate no matter where you place it on a stock. However the recoil of every gun is slightly different, so you will need to make sure you find a location that doesn’t interfere with your shooting setup.

An unexpected benefit of using the JKL trigger is that it gives you a larger area in which to place your Labradar unit, making it more convenient to setup on benches or range stations. I found this a welcome relief since the LabRadar originally seemed somewhat fussy about where I placed it. Now I can place the LabRadar in more convenient locations — as long as it’s still near my gun and pointed at the target correctly, I get consistent bullet speed data.

Are There Issues with “False Positives”?
If there is any downside to using the JKL Inertial Trigger, it’s that a very hard bump or aggressive working of the action can trigger a false reading. However these are easy to identify in your data, because the speed value is way lower than true fired shot values. Simply remove that low entry or otherwise ignore it in your calculations. To be fair, this “bump activation” really doesn’t happen very often once you get used to using the inertial trigger.

SUMMARY — Outstanding Accessory for LabRadar Users
Bottom line — if you own a LabRadar, then definitely get a JKL Inertial Trigger. Priced at just $35.00 this device is not expensive, yet it’s one of the most effective accessories you can buy for the LabRadar. I’ve recommended these inertial triggers to dozens of shooters. Every one of those guys who did buy a JKL trigger says they can’t imagine using a LabRadar without one. If you love what the LabRadar can do, but have been frustrated with shots not getting recorded 100% of the time, then definitely get yourself a JKL Inertial Trigger. It turns a good system into an amazing system. JKL Industries states that its inertial trigger “will work on anything from a .22 LR to a suppressed system or with standard rifle and brake.”

Saturday at the Movies: Chronograph Tests and Comparisons

shooting chronography comparision product review test video saturday movie

To optimize your loads and to generate precise ballistics tables, you need a quality chronograph. Having precise readings of bullet muzzle velocities lets you calculate ES and SD to determine the most repeatable load with least vertical dispersion. Very accurate velocity data is also essential to created a precise drop table for long range and to predict the effect of winds. There are many good chronographs on the market, ranging in price from around $100 to $1000, not counting tripods.

Today’s Saturday Movie showcase features a variety of modern chronographs. We include comparison tests, as well as video reviews of the new, small-format Bulletseeker Mach 4 and AndiScan Micro A2 Doppler Radar chronographs. If you are in the market for a new chronograph and have the resources, you should definitely consider one of these new small chronos, which are easy to set-up and can be mounted directly to your rifle. For those with a limited budget, MagnetoSpeeds still offer great performance for the price. However, you may have to conduct load tuning separately with the MagnetoSpeed removed.

Triple Chronograph Comparison Test
LabRadar, MagnetoSpeed, and Shooting Chrony Alpha Master

This video has an interesting comparison test with three chronograph devices operating at the same time. A Shooting Chrony Alpha Master unit was set up downrange, while a modern LabRadar was placed to the right side of the rifle. On the barrel of the rifle a MagnetoSpeed chrono was attached. This allowed the tester to compare shot velocity values from all three chrono systems at the same time. The video creator explained: “I was curious to see if my old [Shooting Chrony] chronograph could still give me useful velocity information compared to using the newer MagnetoSpeed and LabRadar.”

Chronograph Functions and Features — Vortex Nation Podcast

In this 78-minute video, experts from Vortex explaining how modern chronographs work. The discussion covers the technical features of various chronographs. Multi-time F-Class National Champion Ian Klemm and former sniper Tony Palzkill examine different chronograph types, explaining how they operate. Ian discusses the pros and cons of different chronograph designs, and provides many good tips for chronograph owners. This 78-minute discussion covers multiple chronograph designs, including LabRadar, MagnetoSpeed, and Caldwell Ballistic Precision. There is also extensive discussion of ballistics in the first 20 minutes.

MagnetoSpeed vs. Caldwell Ballistic Precision Chronograph

In this video the host compares a MagnetoSpeed with an older, first generation Caldwell Ballistic Precision Chronograph, mounted a few yards downrange on a tripod. The tester favored the Magnetospeed saying it was “incredibly accurate” while being much easier to set up and transport. He also says the MagnetoSpeed App was very “user-friendly”.

Bulletseeker Mach 4 Radar Chronograph (Rifle Mountable)


NOTE: Skip Forward to 5:40 to see the Bulletseeker field-tested as mounted on rifle and on tripods.

The Bulletseeker Mach 4 is a new radar chronograph that mounts directly to your rifle. The advanced Bulletseeker features 120 Ghz radar with a beam-forming lens. Developed in Europe, with made-in-Germany core components, this unit is sold in the USA for $999.00 by Longshot, trusted maker of long-range target cameras. We think this is a game-changer. You get advanced radar ON YOUR GUN, with no need to haul around a bulky LabRadar.

Comparison test with the Bulletseeker Mach 4 and LabRadar

Another Bulletseeker tester was very impressed: “Based on my experiences with the device it seems like a good product that does everything it advertises. All the benefits of a LabRadar without the drawbacks.” (SEE Product review HERE.)

AndiScan Micro A2 Doppler Radar Chronograph (Rifle Mountable)

In this video, our friend F-Class John tests the innovative, ultra-compact AndiScan Micro A2 Doppler radar chronograph. This unit is small enough that it can be fitted to your rifle, or attached to a front rest or mini tripod. John tested an early pre-production model. The production model is now available for 800 Euros on the SQI-AndiX eShop. The manufacturer notes: “The next large 2023 production series is expected to be ready by the end of February.”

Product Description: “The AndiScan Micro A2 is an advanced ballistic velocity Doppler radar for measuring muzzle velocity of projectiles. It operates in 24GHz frequency band. It is a highly integrated and extremely small form-factor device that is intended to be directly mounted on the rifle. This frees the user from a complicated setup alignment and it also allows to perform measurements under dynamic conditions. It is the first device [with] this form-factor on the public market.”
