Sporter Barrel-Mounted Ballistics Chronograph Kit, Black, Ultra-Compact Case

I have wanted a chronograph for years but I haven't done much reloading in several years. I recently decided to load for the Marlin 336 in 30-30 so I got out My old Rock Chucker set and put together various loads. I put the question out here whether this unit could be used on a lever gun with a tubular magazine and I got a myriad of answers both yes and no!! I contacted the manufacturer and they said it could be used mounted on the side of the barrel rather than beneath. Well with some fiddling and several adjustments, it worked. I was able to chronograph several loads with a few hiccups. I'm going to load up some more ammo and go back at it again and I'm sure I can improve my results. It is really easy to use and very beneficial if you are shooting at a public range which would really hamper the use of a classic style chronograph. I will update this review after further use but after my first trial, I am impressed!!!

Should’ve bought it sooner !

Real easy to use and set up. Have to assume it's accuracy since nothing to compare to yet. Digital readout is simple to use. Negative side is watch for slippage as you shoot. I shoot a .300 WM, so it may just be the recoil causing it to move toward end of barrel. And, you'd think for the price of this thing, they'd give you a better storage case. The one that comes with it, you have to be careful putting it back in. Long plastic box makes for a tight fit. I used an old pistol case to store mine in. Still this chrono is a heck of a lot easier to set up than the wire ones.

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.

ive had the old habit ears for years but this is a game changer digital read out is basic but does the job records up to 100 rounds before over writing menu is a little trick to navigate but it comes with a nice laminated directions sheet there is a more expensive one that does a bit more but this is a great value! warning is says it doesn't record .22 caliber but i have not tested that over all well worth the money

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'informationssuite 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.

Cumple su función en 308. Un equipo necesario para todo aquel que quiere dar un paso más en la precisión y necesita caracterizar correctamente las velocidades de sus municiones. Al menos V0.

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.
