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 LabRadar’s 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.
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 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.”

NRA Media offers a series of informative videos about the Science of Shooting, covering a wide range of topics, from eye dominance to long-range ballistics. These videos feature high production values, with super-slow motion segments, as well as helpful computer graphics to illustrate the principles covered.
The videos are narrated by Jessie Duff, a top action pistol shooter (and the first women ever to achieve USPSA Grand Master status). Jessie is assisted by talented shooters such as Top Shot Season 4 Champion Chris Cheng. There are over forty videos in the Firearm Science Video Series. Here are five NRA videos, with links to others below. You’ll find all NRA Firearm Science Videos HERE
BULLET TRAJECTORY — Factors at Play and Zeroing Strategies
Host Jessie Duff and Veteran Air Force Sniper and Long Range Expert George Reinas help us understand the factors behind bullet trajectory. NOTE: There are some exaggerations in the graphics in the videos, and inconsistent terminology use, but it’s still a helpful basic primer on the subject of trajectories.
Olympic Gold Medalist Jamie Gray demonstrates the four positions used by competition shooters: Prone, Standing, Sitting, and Kneeling. Helpful overlay graphics show how the human skeleton aligns in each of these positions. This video should help hunters as well as competitive position shooters. If you shoot silhouette, definitely watch this video!
ZEROING RIFLES for Long Range — Tech Tips
The process of zeroing rifles for long range is covered in this Firearm Science video featuring George Reinas, a veteran Air Force sniper. George demonstrates how to adjust his scope to compensate for bullet drop at long range. Our friend Dennis Santiago was involved in the making of this video, which was filmed at the Burbank Rifle & Revolver Club in Southern California.
CHRONOGRAPHS — Calculating the Speed of a Bullet
This video shows a conventional chronograph with front and rear light sensors. The bullet first trips the front sensor and then the rear sensor as it flies over the unit. The difference in sensor time is used to calculate bullet speed. This is not the only kind of chrono in common use today. The popular MagnetoSpeed chrono works by tracking the bullet as it passes over two magnetic sensors mounted on a bayonet-style fixture on the barrel.
The high-tech LabRadar chronograph employs Doppler Radar to measure the speed of a bullet without the need to send the round directly over sensors. No need to set up tripods down-range. Just set the unit near your rifle’s muzzle, on the side. There is also an inertial trigger accessory for LabRadars. Interestingly, this video also explains how, in the days before electric lamps, digital processors, and radar, scientists used a mechanical “Ballistic Pendulum” to calculate bullet velocity using Newtonian physics. The Ballistic Pendulum (shown at right) was first used in the mid 1700s.
EYE DOMINANCE — How to Determine Which Eye is Dominant
Host Jessie Duff and longtime shooter Krystie Messenger demonstrate how eye dominance affects aim and teach you how to determine your dominant eye in this edition of Firearm Science. There are very simple tests you can do to determine your eye dominance. This Editor is right-handed but left-eye dominant. All competitive shooters should check for eye dominance. If you are cross-dominant, you can alter your head position or put a paper patch on one frame of your shooting glasses.

We see comparison tests of cars, cameras, and other hardware. But how about chronographs? What could we learn by setting up three different chronographs, and running a 20-shot string over all three at the same time. One of our Forum members, Randy S. (aka AAA) did that very test with three of the best chronographs you can buy: LabRadar, MagnetoSpeed, and an Oehler model 35P. The MagnetoSpeed was attached to the barrel of an F-Class rig, with the LabRadar placed on the left side of the shooting bench. The Oehler 35P was positioned about 23 feet downrange. The photo above shows the set-up. A 20-shot string was recorded with the results in a spreadsheet.
AAA talks about this interesting experiment in a Shooters’ Forum Thread. Here is his report:
Comparison Testing Three Chronographs
We all have our favorite chronograph. Each gives a number, but how would that number compare to the same round fired with another chronograph? I wanted to know so a friend and I set up the following test with three chronographs: LabRadar, MagnetoSpeed V3, and Oehler Model 35P.
For the test we fired Berger 105gr VLDs over the three chronographs simultaneously. The test rifle was my 6mm BR Ackley (BRA) F-class rig with fire-formed brass and 200 rounds on the new barrel.
Chronogaphs Tested
LabRadar
MagnetoSpeed V3
Oehler Model 35P
Temperature: 86 deg. F
Elevation: 854 feet
Cartridge: 6mm BRA (105gr Berger VLD)
Time between shots: 45 seconds
To start off, five rounds were fired to make sure all systems were recording and to warm the barrel. Then the test was 20 shots fired across all three instruments with 45 seconds between shots. The Oehler was set 7.5 yards from the muzzle so 12 FPS was added to the recorded value.
We were using the internal trigger on the LabRadar. The manual says the Vo indicated is the actual muzzle velocity when using the internal trigger, but not if using the Doppler. The 12 FPS Oehler adjustment (back to MV) was based on the Berger Ballistics Calculator.
The LabRadar Chronograph is on sale now through 12/7/2019. Buy for $499.95, a $60.00 savings.
Results of the Triple Chronograph Shoot-Out:
LR-M is FPS variance between LabRadar and MagnetoSpeed V3. LR-O is FPS variance between LabRadar and distance-adjusted Oehler 35P. You can see all three chronos were very consistent. ES was identical with the MagnetoSpeed and Oehler 35P, while SD was identical with the LabRadar and Oehler 35P.CLICK HERE for spreadsheet.
The tester, Randy S. (aka AAA) says: “Judge for yourself, but I was impressed by all.”
This is a manufacturer’s photo showing the Magnetospeed V3 as mounted. This is NOT the test set-up.
Comments by Forum Members
Our Forum members expressed interest in this Triple Chronograph test. Some confirmed that the LabRadar and Magnetospeed give very similar FPS numbers, based on their own tests:
“Great test and thanks for sharing. I’ve tested my MagnetoSpeed and LabRadar together and results are always within 2-4 FPS of one another.” — Big D
“Very happy to see your numbers support my decision to buy a MagnetoSpeed. Had read reports comparing it to the Oehler and the numbers I get seem to be supported by my long range shooting results. Many thanks for taking the time and effort [to perform] this comparative test. Always good to get actual test results.” — Texas10
“I did a 4-shot test with my MagnetoSpeed and another shooter’s LabRadar a couple of days ago. The results were within 4 fps with the LabRadar being optimistic.” — Pat Miles
Forum Member Powderbreak studied AAA’s original spreadsheet from the chronograph trio test, then figured out the shot-by-shot FPS variance between the machines. He concluded that all the machines performed very well. Powderbreak posted:
Analyzing the Triple Chronograph Test — What Can We Conclude?
AAA did a great job of comparing the 3 chronos. What conclusions can be drawn?
1) I have not checked the manufacturer’s claims of accuracy, but the three chronos are very close to one another. There is no way for us to determine the actual true velocities, but we do not need to do so. Any of the chronos would be more than adequate for an accurate shooter.
2) The resolution of the three chronographs is actually pretty astounding. One foot per second (FPS) is a resolution of 0.033%.
3) AAA did a great job of reloading a very consistent round. With an extreme spread of 33 fps out of 3014 for 20 rounds, that is only 1.09% total spread of velocities.
4) There is a closer velocity match between the MagnetoSpeed and the LabRadar, but that does not mean the Oehler is less accurate. There is simply an offset between the Oehler and the other two. This could be due to the greater distance, the location, or the internal working of the Oehler.
5) Believe your chronograph, it is probably the most accurate reloading tool that you own.
Brian Litz of Applied Ballistics carefully explained the operation, set-up, accuracy and comparison of AB’s chronographs in his books. [Those books] are well worth the money, and give great insight into the workings of chronographs.” — Powderbreak

Today’s precision shooter is connected. He or she is likely to bring a number of electronic items to the range, such as a smartphone, tablet computer, Kestrel, LabRadar chronograph, and more. These digital devices all require electricity to operate. Unfortunately, most ranges don’t include convenient charging stations for your gadgets. Therefore you need to bring battery back-up. Here are three good options, with storage capacities from 10200 mAh to 42000 mAh. The first unit is fully weather-proof, so it is good for hunters and tactical shooters exposed to the elements. The largest power pack, with AC outlet, is quite versatile and works well on car-camping trips.
1. FosPower 10200 mAh Waterproof Charger, $29.99
When you’re at the range or on a hunt, it’s smart to have a USB-output battery pack for smart phone, target-cam monitor, even a LabRadar. There are many battery packs available, but most are fairly fragile, with exposed ports. This “ruggedized” FosPower 10200 mAh charger is different. It is waterproof, dust-proof, and shock-proof. (IP67 certified: dust and water resistance for up to 3ft/1m for 30 minutes under water.) It can handle all that a PRS competitor or hunter can dish out. It even has a handy LED light. Right now it’s priced at $29.99 with FREE Shipping (on orders over $25.00).
2. EasyAcc 20000 mAh Battery Pack with Fast Charging, $37.99
If you want to charge multiple devices, such as a tablet and a LabRadar, you need serious capacity. The EasyAcc 20000 mAh battery pack can charge up to four devices simultaneously. Notably, this $37.99 Battery Pack charges faster than most other 20K packs. It has two power input ports, allowing it to fully charge in 6-7 hours. (We have another 20000 mAh battery unit that takes over 16 hours to fully charge!). This unit will charge an iPhone 7 six times, a Samsung S8 four times or an iPad Mini two times. Note, 77% of Amazon purchasers rated this unit Five Stars (with 13% Four-Star reviews).
3. Webetop 42000 mAh USB, 12v DC, 110v AC Power Station, $108.99
Many folks have asked us “How can I use a laptop, chronograph, or electronic powder dispenser that requires 110 volt AC power when I’m at the range?” Sure you can take power from your car’s 12 volt cigarette lighter jack, but you’ll still need a very long cable and a 12 volt to 110 volt step-up transformer. If you run a cable from the parking lot to the bench or shooting bay you’ll have to leave a window open in your vehicle and fellow shooters can trip over the long cord.
A better solution is to get a portable, combo 12 volt + 110 volt power unit. This versatile 42000 mAh Webetop Power Station will drive a 110v device, plus charge a tablet and cellphone, all at the same time. You can run a LabRadar for days with this power-pack. It will also power CPAP machines and other 12V devices. One nice feature is rapid charging. Before your range session or camping trip, plug this into the wall. It will get fully charged in 7-8 hours. It’s a bargain right now for $108.99 on Amazon.

Here is Tye Sim’s .270 Win Mountain Rifle: “This is off a trued and blue-printed Rem 700 action. I love it.”
For today’s Sunday GunDay feature, we thought we’d present a selection of rifles featuring both cool gear and scenic venues. We’ve got quite a mix — hunting rifles and competition rigs, full customs as well as factory rifles. And there are some interesting calibers including 6.5 Creedmoor, .270 Win, .308 Win, plus a couple WSM variants. Enjoy our Sunday lineup!
To begin, here is the beautiful Blair Atholl range in Scotland. Owner Gary Costello posted: “Great day today, weather was interesting but not as bad as we thought!” Gary, a top F-Class shooter in the UK who often runs a .300 WSM, has been featured in a previous Sunday GunDay spotlight story HERE
Andrew Stone is an F-Class shooter from the Southern USA. Here his F-Open rig is set up for load testing from the bench at his beautiful, tree-lined home range. Targets are at 600 yards. Andrew is using a SEB front coaxial rest and LabRadar chronograph mounted on an aftermarket tripod.
In the photo above is Brian Harder’s handsome .308 Win F-TR rifle. This features a Kelbly action, McMillan stock, and Vortex scope with level. Up front is a SEB Joystick Bipod (Joy-Pod) with accessory ski-type feet. Note that Brian runs a front scope extension tube (sunshade), and a mirage shield on the barrel. These items do make a difference, particularly on hot summer days!
Here’s another British Beauty. This is the 7mm-270 WSM F-Classer belonging to Forum member Ian B. (aka “Elwood”). It features a Stolle Panda F-Class action, 32″ straight-contour Bartlein barrel, and a custom Joe West stock, modified by Ian and then hydro-dipped in brilliant blue by Hydro Graphics in the UK.
Factory rifles can be interesting too. That’s pretty impressive accuracy shown by Steven Castleman’s Bergara B14 HMR chambered in 6.5 Creedmoor. On this day Steve was shooting Hornady factory ammo loaded with 147-grain ELD Match bullets.
Here’s a stunning silhouette of a Savage 6.5 Creedmoor. Ed Whipple posted: “Borrowing a Savage 10 BA Stealth from my buddy Ron. He wanted a 100-yard head shot on a hog. I’m not listening to Ron any more. Federal Fusion bullet ain’t messing around.”

A carpet is used up front for smoother tracking with the Joy-Pod’s flat, ski-style feet. The arms of the Joy-Pod were painted to match the stock. The rear bag features low-drag material on the ears.
On Sundays, we feature notable rifles that exhibit fine craftsmanship, quality components, and noteworthy shooting accessories. Today we are featuring an F-TR (F-Class Target Rifle) rig that showcases the types of components, and accessories used by top F-TR competitors — including a coaxial bipod and Labradar Chronograph. If you’re considering getting started in the F-TR game, take a close look at this modern F-TR build from Forum member DM.Oakes.
Modern F-TR Rig with Borden Action, Krieger Barrel, and SEB Joy-Pod
This handsome .308 Win F-TR rig features a smooth-running Borden BRM action, 30-inch 1:10″-twist Krieger barrel, and an X-Ring Laminated Wood stock. Up front is a coaxial “Joy-Pod” joystick bipod. This is a state-of-the art, wide footprint bipod used by many competitors at the Worlds in Canada. The long joystick allows the “driver” to quickly adjust both elevation and windage in a smooth, continuous motion. The Joy-Pod can be adjusted so it will hold setting during the shot — you don’t have to “hard-hold” the joystick. Many shooters let the joystick slide through their fingers as the rifle moves back on recoil. With a little practice (and careful placement of the rear sand-bag), the tracking is excellent and you can slide the gun right back to point of aim after each shot.
This F-TR rifle is shown during load testing with a LabRadar chronograph.
» Full LabRadar Field Test/Review by Ray Gross
If you are considering purchasing a LabRadar Chronograph system, we strongly suggest you read the very thorough and informative LabRadar Review by Ray Gross, past Captain of the USA F-TR team. Ray notes: “It takes me about 3 minutes to set up [my LabRadar] at the range. Because there are no downrange screens, I do not have to hold up other shooters on the range like I would when setting up a traditional chronograph. The convenience alone will mean that I will use it more often than my old chronograph. Every time I take it out, I enjoy it a little bit more.”
