## Description

Great Product

Review: For rifle use, this is the most reliable way to measure true MUZZLE velocity. I have had the privilege of running the MagnetoSpeed side-by-side with a Caldwell Pro chronograph, a Garmin Xero, and LabRadar all at the same time with some 20 odd rifles of varying performance and velocities. After an extensive session, with over 500 rounds fired, and the data collected and analyzed, the MagnetoSpeed was the clear winner. To clarify, the usual chrony has weather limitations and has the disadvantage of needing to move forward of a firing line to set-up (which can be a pain on public ranges). The Xero comes in second best, but is the most convenient by far. The real reason why the MagnetoSpeed reigns supreme, is that there was never ANY anomalies in the data. The LabRadar had too many anomalies for my liking, and is overly dependent on set-up parameters (including close by obstacles, walls, baffles etc.). Overall, it is hard to beat the Xero for convenience and accuracy combined, but when data accuracy is all that really matters - Magnetospeed is King! No extrapolated results, just true muzzle velocity.
Review: 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.

## Questions & Answers

**Q: Does this effect accuracy by changing barrel harmonics?**
A: I have attached the V3 bayonet to many rifles over that past year of load development and testing and have found the following. I have personally run it on a .223 with a varmint profile, both suppressed and unsuppressed and found no impact shift with this barrel in either configuration. I have also run it on several sporter profile barrels including 7mmRSAUM, 300 RSAUM, 300 RUM, and 30-06. With these rifles I have found the impact shift to be so minor that I was still able to mark under 1MOA, 3 shot, 100yrd groups with all but the 300 RUM, with that rifle the best I could shoot was just at 1MOA. I reconfirmed shots again without the bayonet on all rifles tested and found the position of the hits moved a little but the size of the groups were still about the same as with the bayonet. All of the rifles I've tested have been completely free floated and were shot using a bipod and rear bag during testing. The V3 bayonet only weighs 7.8oz with the all of the spacers needed for use on a sporter barrel so I don't think you should see enough change in impact to warrant not buying one.

**Q: Will this chrono hold up to heavy recoil rifles?  (458 socom, 50 beowulf, 50 lott, 50 bmg, etc)**
A: Used it with a .338 Lapua Mag.

**Q: When recording shot strings, can you return to a saved string and add shots to it after moving to a difftent string?**
A: I am pretty sure that once you have archived a shot string, you can't save additional shots to that string.  However on the V3 you can open the archived data in a spreadsheet and manipulate the data there - for example merge two shot strings to determine the Extreme Spread and Standard Deviation.

**Q: I know the 1/4" bar is supplied so the projectile doesn't hit the arm, but how far away from  the bore line will it read accurate velocities?**
A: I have used it as far out on the barrel as I could position it with fine accuracy.  That is about 4 or 5 inches.  The reason I positioned it that far from the muzzle was because a huge muzzle brake on a 338 Lapua Mag. it wasn't possible to mount it any closer.  This chrono makes everything else obsolete.

説明通り銃口にベルトで装着するだけで弾速の測定ができてしまいます。 計測部に搭載している電池だけで稼働するので測定する場所を選びません。
