Great value for what you get
Reading online reviews, I know a lot of people have issues with this model. One I was even concerned about was strapping it directly to the barrel, this can mess with barrel harmonics and will affect your shot (-1 star for this design flaw).There are several commercially available optional mounting systems, but they are spendy. A lot of people have come up with amazing mounts using the picatinny rail and adjustable camera arms and machining custom brackets. I went a similar direction, since I don't have the specialized tools. Using a small picatinny riser and male/male camera thumb screws along with a cell phone bracket, it works like a charm (see pictures) all for about $15 with parts found on Amazon. This floats the bayonet just a fraction of an inch under the barrel - don't even need the rubber pad(s) and using a second one, gives me a place to mount the digital data logger.This also lets me easily switch between rifles (both AR platforms) by undoing the riser & snap it onto the other rifle. Just need to figure out how to attach it to my long rifle using the same or similar set up. (Sorry, staging the pictures I clipped it 1 spot too far out, so it's touching the muzzle device - normally it would go back 1 space and not touch.)Accuracy is very good too, I also have a Caldwell Ballistic chrono and the readings have been pretty much dead on shooting through both. Just can't use the Caldwell at indoor ranges since they frown on going past the firing line, the MS Sporter definitely solves that issue.I have no doubt the V3 is even better, but it's just out of my price range and this one does exactly what I need it to when it comes to testing hand loads.

I bought this chrono to see where I am at on my ar15 loads, and fine tune them. This thing has worked flawlessly! No errors yet, with about 500 shots. I was concerned about it getting loose on my 20" bull barrel after reading the reviews here, but have had absolutely no issues.... it stays tight shooting .223 and 5.56 rounds, but it isn't exactly a magnum rifle. If you loosen the knob BEFORE clinching the strap around the barrel, and then tighten it down, it works very well. I would definitely recommend this chronograph. Once you put it on the barrel, check to make sure it is parallel to your bore, and from there, you're golden. It is very easy to learn the menus, and the instructions, while basic, explain all you need to know about using it. I wish I could use it for my bow, but at least I don't have to worry about shooting it, or getting in anyone's way at the range.

4.0 out of 5 stars Valuable tool, but feels cheaply built
Reviewed in the United States on November 17, 2019
Verified Purchase
I love having this thing, and have used it successfully on all my rifles, from an AR-15 with flash hider and front sight post to a K98 Mauser, to my modern Savage 10 and 11. It is compact and lightweight, and easy to pack along in the backpack when heading into the hills to do target practice. Once attached, I can engage different targets and move around, and don't have to worry about lining up perfectly with a tripod-mounted chronograph.
The only downside of this portability is that you can't use it for handguns (or airguns or archery), like you can with a Caldwell.
The biggest flaw is the clamping mechanism is flimsy and it slips out of position after a few rounds. You have to check it after every round or two, to make sure it isn't slipping out of position and into the line of fire.
This thing is made out of extremely cheap feeling plastic. I've got nothing against polymer gun parts, but this thing is made out of the same crappy plastic as McDonald Happy Meal toys or 99-cent store party favors. It's seriously that bad.
But it works well enough, and gives valuable data, and is way cheaper than most other chronographs, and is much more portable and field-usable than a tripod-mounted Caldwell.

5.0 out of 5 stars Magnetospeed chronograph "Must Have" for serious shooters.
Reviewed in the United States on July 15, 2016
Verified Purchase
Amazing chronograph, setup takes some fiddling the first time but after that its super fast and easy to do, no more calling cease fire at the range and setting up a chronograph out in front of you hoping that it works, no more problems with optical sensors getting washed out by bright sunlight or not working because its overcast. Magnetospeed knocked this one out of the park.

Add the XFR cell phone plug to the equation and the days of optical chronographs are numbered. If you are in the market for a chronograph and are on the fence between this and something like an Oehler Optical Chronograph trust me spend the extra $50-75 on the magnetospeed I have an old Oehler, and while it has served me well over the years and provides very accurate data the weight size and hassle of setup that was weather dependent severely limited my use of it.

With the magnetospeed I can just toss it in my range pack, and leave it there, Its so small and light you can take it anywhere and use it under any conditions.

I have an "SPR" contour barrel, so its not a medium profile its a little lighter, I shot 75rds out of that gun two days ago, and got a huge data pool for cold ,warm and hot bore , for three different types of ammo,all while I was shooting groups. And as far as I could tell I was not seeing any loss of accuracy. I had a guy one one side of me with a black powder musket shooting cow sized plumes of smoke every shot that hung over the range like fog, I couldnt have used an optical chronograph under those conditions. The magnetospeed didnt bat an eye.

Of course putting anything on the barrel changes harmonics and vibration node points, but with a relatively light profiled barrel I saw no negative effects from it hanging on the end of my barrel. So if you have a lightweight hunting barrel you may see a slight loss of accuracy, but the magnetospeed is so light I wouldnt worry.

The ease of use and lack of negative effects allows you to get incredibly accurate and detailed data for a wide variety of conditions, I plan on getting velocity for at least a few rounds every trip to the range, that way I can measure what effects temperature and barometric pressure have on my ammo.

1.0 out of 5 stars Most useless device
Reviewed in the United States on July 3, 2022
Verified Purchase
I received the unit Saturday morning just in time to go to the range Sunday morning. I really wanted to see what my loads were doing so I could dope my rifles. Once I got to the range I hooked up the device on my bolt action and fired a shot, I didn't get any readings. I fired another shot and still no readings, I swapped the rubber that holds onto the barrel to see if that was the issue, still no readings. I tried another rifle since I went with two in order to document the settings up to 500 yards, still no readings on the second rifle. I ended up giving up and just shooting to the best of my ability with old settings in my ballistic program.

When I got home I wanted to make sure that I wasn't doing something wrong so I connected the device to my .22 air rifle since I can shoot that in the house. Still no readings after shooting the air rifle, I adjusted the sensitivity to 1 and then 2, still no readings just dashes on the screen.

I tried my .177 air rifle and moved the barrel in different positions on the mount, still no reading. Tried the thicker rubber on the mount, still no readings.

Did I get a dud or is this thing just garbage? I have read many posts where others are saying that they are not getting any readings and they just gave up. I have also seen many posts where others are getting readings right out of the box. I am not impressed as I shouldn't have to be doing all this back and forth to get something to work, it should be working right out of the box.

First thing Tuesday morning this item is being returned. I liked the idea that the device is very small and compact, but its not worth the headaches.

super service, commandé le 12/04/2021 et reçu le 13/04/2021. Le produit à l'air de bonne qualité, après déballage tout y est, prêt pour l'utilisation.
Testé ce jour, sur carabine 22lr avec plusieurs projectiles. Enregistre la vitesse à chaque tir en mètre par seconde, à la fin de la séance, ça nous indique la vitesse de chaque tir. Il nous donne la moyenne des vitesses calculées sur 12 tirs, il indique aussi la plus grande vitesse ainsi que la plus basse, le calcul des différences est aussi indiqué. Dommage que pour obtenir ces informations en fin de séance qu'il faille obligatoirement connecter le boîtier au capteur.

Premier contact plutôt encourageant. très bon système facile à poser sur canon, mesures fiables faites en comparaison d'un autre système mis en parallèle. Quelque soit l'éclairage cela fonctionne très bien.

petit bémol sur quelques points:
- Manuel en Anglais,
- Boîtier un peut compliqué à manipuler et à programmer
- Être obligé de se connecter au capteur pour relever les données en arrivant à la maison
- Dommage que l'adaptateur XFR ne soit pas livré dans ce kit.

Samedi je le test avec du 308W, je ferai un complément d'informations

suite au commentaire du 13 avril.
Système testé avec calibre 308W, tout simplement parfait. très précis et fiable. Utilisable sans problème dans des endroits restreints.

Je ne regrette pas mon achat, je conseille ce produit.

This is the simplest chronograph that I have ever used. First, ownership does not break the band, Second, the instructions are straight forward, Third, it is accurate!!! The only way you could mess up is if you don't follow the instructions. Make sure of the path of your bullet AND YOU ARE GOOD FOR GO!!! I am happy with this purchase and even though it says for center-fire rifles it will work with the 17HMR.

Reviewed in Germany on March 16, 2020

Etwas enttäuscht muss mein Gesichtsausdruck ausgesehen haben, nachdem ich das Gerät aus der Verpackung genommen hatte: Handelt es sich hierbei etwa um ein chinesisches Kinderspielzeug? Von dem Preis angemessener Wertigkeit äußerlich keine Spur... Billig und zerbrechlich anmutende Plastikkonstruktion, die primitive, nicht gerade vertrauenserweckende Montagevorrichtung mittels Spanngurt.... Zur probe an der Waffe angebracht, schien alles ok... Bei der nächsten sich bietenden Gelegenheit auf den Schießstand. Mit den Standardeinstellungen 17 Schuss abgegeben (3 Gruppen á 5 und 2 Einzelschüsse) - und siehe da- der MagnetoSpeed scheint zuverlässig zu funktionieren, imKaliber .45-70 Gov. mit 5 verschiedenen Laborierungen getestet, lagen die Werte einer Laborierung (im für dieses Kaliber realistischen Geschwindigkeitsbereich)jeweils eng beieinander und entsprachen in einigen Fällen fast auf den Meter/s genau den berechneten Voraussagen der Innenballistiksoftware GRT (pulversortenabhängig). Unterschiedlich starke Laborierungen spiegelten sich eindeutig in den Messergebnissen wider. Auch die bei einer anderen Gelegenheit durchgeführten Messungen mit einer weiteren Laborierung entsprachen den Erwartungen, die geringen Abweichungen der V0 wurden durch enge Streukreise auf der Scheibe bestätigt. Einfache Montage, jedoch etwas primitiv das einzeilige Display mit nur einem Bedienknopf, der die Bedienung nicht gerade erleichtert, will man etwas an den Einstellungen ändern, z.B. die Empfindlichkeit. Mit den Standardeinstellungen aber sozusagen "plug and play"-fahig... Die heißen Gase an der Mündung scheinen dem Gerät nichts auszumachen. Auch unterwegs im Revier nutzbar, allerdings konnte ich aufgrund der kurzen Nutzungsdauer noch nicht testen, welchen einfluss der montierte MagnetoSpeed auf die Laufschwingung und damit auf die Treffpunktlage hat. Alles in allem, habe ich den relativ hohen Preis verschmerzt und den Kauf nicht bedauert.
