V3 Barrel-Mounted Ballistics Chronograph Kit, Black, Hardcase

I really struggled to place this order. I am new to precision shooting after 50 years of shooting only at game. It is expensive but I couldn’t spend money on what looked like a much inferior product. Received my magneto on Monday and took it out today. The unit powers up once it is connected up correctly. There is no on and off switch. I started out and the first shot it read and looked good. Fired four more shots and looked at readout and I only had the first reading. Looking at the magneto it was obvious I didn’t have it strapped on hard enough. I readjusted it and continued to shoot the second string. No problems. Third string it was loose again. I reevaluated my setup and continued on for the rest of the shooting time with no problems. I like the function of the device. It is very intuitive to use if you have used a electronic device in your daily life. I’m 60 and it was very easy to use. The display is great and just amazing to see results, the averages, and standard deviation. It was easy to store results with the archive function. I look forward to many years of rifle ballistic tests to come. If this review helped at all please like it. If you read this far I give you one last tip to strap it to your barrel as tight as you can then tighten with thumb screw on bottom of strap lock.

For the $ this is a very accurate chrono and I got a lot of value for the money spent. It has since been replaced by a Garmin Xero C1 which is SO much easier to use. I'm keeping this though as a backup. Can't fault its accuracy. Just a bit cumbersome to attach it to your rifle. Even with an expensive aftermarket mount the POI shifts a bit. But again, I gathered LOTS of great data with the MagnetoSpeed and its a great piece of gear.

Very happy with this chrony. Yes it’s a little pricey but you get what you pay for. Really the only option when you are using a public indoor range. Mounting can be a little tricky, but once you figure out the right combination of spacers and it’s properly secured I’ve had no issues with it staying in position on my .308. I usually just mount the pick-up rail to a suppressor first and then attach the suppressor with the whole unit to my rifle. The display is pretty intuitive and easy to read even outdoors. So far I’ve put about 200 rounds over it and it has never failed to pick up a shot. Still running on the original battery over five sessions spread out over a few months time. Love the included hard case - keeps the unit safe and secure and slides right in to one of the external pockets of my Savior precision rifle case. Really the only negative is that the attached rail, although not all that heavy (the mount probably weighs as much as the pick-up rail), will affect barrel harmonics, so you don’t want to use chronograph shot strings to gauge accuracy or POI. Overall though I highly recommend.

I have been using a standard Chronograph that relies on sunlight to trigger a bullets presence over its sensors. If the sun is positioned just right and the bullet's path is right over the sensors, all is beautifully captured. The software and its Bluetooth connection to my tablet or phone made its use simple and logged all data in an organized fashion, great design. But it occasionally missed a reading. If I'm shooting a LADDER for a new load, this really ruined my day, unless I had duplicate or triplicate copies of each load.So I went to the MagnetoSpeed for a more reliable data collection. And indeed, I succeeded. I have yet to miss a data point after five sessions, approximately 300 rounds. So reliability was a big gain, but software ease of use was a disappointment. Its software and interface to portable devices is primitive or nonexistent compared to my old Bluetooth chronograph. Yes the data is there and retrievable, but the elegance is gone. So there is a tradeoff, and I'll take the reliability over the loss of modern software.Besides reliability, there is another big advantage of the magnetospeed, setup is super fast and easy, no more aligning the chronograph sensors to the expected bullet path, and no more lugging around tripods and screens. Love the setup ease.The final disadvantage of the MagnetoSpeed is that because of its attachment to the rifles barrel, the harmonics of the barrel does change, and the point of aim and group sizes are affected.Personally I am happy with this device, but I'd like to get my hands on the LabRadar to compare ease of use and reliability. If you read enough reviews about both devices, the reliability of the MagnetoSpeed over the labradar appears to win and is why I chose it. I'll wait for the next generation of LabRadar to see if its reliability can be improved to make it a worthy of my investment. Do your homework before investing your money.

This is a great chrono. Expensive? Yes. Worth it? A qualified yes. This is work every penny if you:1. Reload and use a chrono a lot.2. Want the most accurate reading available on the retail market for less than thousands of dollars.If both apply then it is even a better deal. It is truly nice to be able to set up, adjust and take down a chrono without have to cease fire at a range. Heck, some ranges don't even let you use a traditional chrono.These are far more accurate and consistent that the light based chronos. You can use it in any light condition and even indoors. It is easy to use with a good menu system and simple controls, nothing to "techy". Data is saved in a standard CSV file that can be opened with any spreadsheet program like Excel.Had mine at the range yesterday and had a lot of interest, I may have even sold 1 or 2. Maybe MagnetoSpeed should give out referrals:) I also recommend getting the accessories for tapered barrels and the adapter for rail system mounts. This will help make sure almost any firearm you have will work.A final note is that MagnetoSpeed has great service and support. My original purchase had issues reading the shots. One call and they shipped a new bayo and all is well.
