I am not allowed to discuss prices and take orders on the open forum.
Please send me a PM or email info@mysticprecision.com
Or you can just go to Magnetospeed website and add 1.08 to the prices listed. hopefully, the dollar doesn't tank anymore. Prices are subject to change without notice.
Of course, there is Canadian Ship and tax... Less then ordering from the US directly.
Be amazing if more US products start to work out math so we are closer to US retail plus exchange but I am not holding my breath.
I am taking orders for shipment coming up Dec. Can't say it will make Xmas but it will be soon.

At the risk of being a highjacker:
How do any of us mere mortals know if a chronograph is accurate, as many have claimed this one is?
I've always wondered this, and have several times lined up a couple and shot them together. In one test, with a Shooting Chrony and a RCBS unit, numbers were very inconsistent, and, if memory serves, the RCBS showed a much higher velocity on average. However, on some shots the Chrony was higher. (And perhaps it was the other way around, I no longer have the records)
Another time, I shot a (different) Shooting Chrony and a CED M2........now, based on long range trajectories for several loads, I had always suspected the Chrony was showing me falsely high velocities...... The test showed this to be true (if you trust the M2) by 78fps on average. However, once again, some shots would show higher velocity on the M2. So the upshot of all this caused me to buy an Oehler, believing that they are high quality, and should be more accurate, due to comparing two readings. And, of course, everybody needs three chronographs.....
I realize the Magnetospeed uses a different method of reading velocity, but the question still remains, to my feeble mind, as to when and whether we are getting "accurate" data.

You are absolutely right - you don't know if the LCD screen is telling you anymore info then any other screen.
The confirmation occurs when real world LR shooting matches up with predicted calculations. Ballistic software is getting very good and reliable within the inputs of the user.
Scopes are tracking very nicely (at least better ones are).
BCs have been calculated that have been backed up by other means of measurement and are getting far more robust.
The ability for a shooter to create a reliable firing solution for LR is now excellent.
SO.... if your chronie suggests a speed of so much but the real world results are way off, something in the math or input is wrong.
If the velocity variation over a number of shots is tight but the LR vertical and grouping is horrid, again, something doesn't jive.
Optical Chronies by design have had reliability issues from the beginning. They are just very inexpensive to produce so shooters use them. Very good at offering ballpark values but I wouldn't waste time crunching math with the data generated from these units.
The mechanism of the magnetospeed has been proving to be very robust and many shooters have tested against other benchmarks to prove the performance. In general, feedback on the product has been very positive.
Simple test would be to make up a batch of ammo as precisely as possible. Get some data on that the ammo. Repeat this under similar ambient conditions and if the readouts continue to be consistent, then the device is working consistently.
Is the readout correct in absolute terms? I use the drop chart to verify accepting that no system is 100% perfect. If I am within 1/2 - 1 min of predicted at distance, that is good enough for me. Most of us do not have access to doppler radars.

Another factor to remember when comparing results of the Magnetospeed and any optical chronograph, is that the magnetospeed measure bullet velocity immediately as it exits the barrel, before it stabilizes. I would like to believe that there is a fair amount of velocity loss in the first 10-20 feet of the bullets trajectory as it wiggles and waggles trying to stabilize; I couldn't say how much though. At the end of the day the results should be repeatably different, factoring in errors in the measuring, and actual differences in velocity.
