Oehler 35 vs Magnetospeed V-3 ? which one

[LynnJr]

is there a reason why, i read a lot of the bullet and ammo manufacturers use the Oehler, i like the printer but also like the ease of the magnetospeed .
great reviews on both units if you know something about the Oehler please elaborate
thanks for the replies guys

If you go to the magnetospeed website they don't list any error numbers.
They tell you about another source who used a Oehler and the magnetospeed was 99.6% as good.
There technical info page has nothing of any value to it.

I have both a Oehler 33 and 35P chronographs, and a MagnetoSpeed V-1. I find the Magnetospeed is more useful for its quick setup and ease of use in developing rifle loads. Because all my rifles use heavy varmint contour barrels there is little or no effect of the barrel mounted bayo. The accuracy between the Magnetospeed and 35P is within a few fps, not enough to be concerned with. Also the Magnetospeed can be adjusted for sensitivity when firing .17 or .20 caliber bullets that may give optical sensors a fit. Another annoyance is when testing in close proximity to other shooters at a public range their muzzle blast may cause an errant reading that must be deleted from the string, something the Magnetospeed is immune from. The most significant difference is when one or more Oehler skyscreens become shaded in the afternoon, they quit working, and the chronographing session is over. The magnetospeed unit carries on under all conditions. In addition, I can transfer the Magnetospeed data from the SD card to a Excel format I made for easy archiving. See below:



The other consideration is that the Magnetospeed is so easy to set up, it can be used anywhere, even while hunting varmints if some strange mood overwhelms one's sensibilities. It's just easier to do if using a range where chronographs are a PITA.



There are advantages and disadvantages to everything, in this case use your judgement.

Thank you Wrangler John ,you convinced me into the magnetospeed

I shoot over a 35p in a cave in almost complete darkness and have never experienced any of the issues I have seen posted here except it does take longer to set up.
The MagnetoSpeed cost about $100 less than the Oehler so if it's ease of set up and velocity doesn't matter you can get chronographs for $80 that work just as well.
Not trying to slam a product but it is not even remotely close to an Oehler it is just very easy for the average Shooter to use.

Nice to see you back Lynn, I thought you picked up your toys and went pouting home...

[orangeusa]

Magnetospeed was at 99.9% accuracy when compared to photographic measurements. Surprising that they compared their accuracy to another product instead of pointing that out.

The ignorance in this thread is making me want to pack up again. No pouting however you can't heard cats.

Lynn,

Don't be so upset with others, some are trying to learn...but I do know how you feel. Sometimes people don't mean to but spread bad information. I get that type of manure spreading bothers you...

Yes, the internet is kinda like trying to heard cats, heh?

That said, I would like to have a chrono but it seems like most other stuff...the guys who own a specific model/brand are always more than willing to recommend the one they own.

It is almost identical to asking about a reloading press... *gd&r*

You heard cats or trying to herd cats? Either way, you have a "holier than thou" attitude. Good luck with that on CALGUNS.

Give info or clarification on FUD in this thread, otherwise, keep your generalizations to your self. We may be ignorant ( in your eyes, hot shot), but we aren't stupid.

Interesting.

Problem with the Oehler 33 or 35P (the old 33 uses the same skyscreens) is that when one or more skyscreens falls in shade, the imbalance in signal output causes errors. Sometimes the light diffusers can be removed to increase the sensitivity of the photo sensors but this is only a temporary solution and one that still results in errors. This is why I arrive at the range early before shadow from the firing line overhead creeps over the screens. Also, I have to use a firing position where trees will not shade the sensors as the day progresses. This is just the nature of a photodetector chronograph based on visible light without an illumination source. This happens every time, invariably, and can be frustrating. With the screens tethered to a cable there is little latitude in extending them past the shade line. It would really be great for somebody to come up with WiFi or Bluetooth connected screens, and a LED illumination source, better still, ones that automatically turn on when the light level drops or is inconsistent. Until then overcast days are my friend.

The Oehler chronographs are therefore reliable only where they function, and completely useless where the signal drops out. Part of life using public ranges. When I shoot rifles with muzzle brakes, I bring the Oehler, rather than sandblast the Magnetospeed Bayo, although Magnetospeed has designed the newer V-3 to be more blast resistant. Amazing how much stuff comes out of my newest varmint rifle's 6mm BR muzzle brake.

In fact the Magnetospeed product is very rapidly evolving. Now they have a Large Brake Adapter designed especially for the .338 Lapua Magnum and larger, that clamps on to a large diameter barrel via an aluminum fixture. Then there is the XFR adapter that allows data to be downloaded directly to Apple and Android devices. Even better, they have a rail adapter that allows the bayo to be attached to rifles and handguns with a bottom rail. I may be an old guy that can still harness a carriage horse, and as a kid lived in a house that had gaslights and an icebox, and still uses a dumb flip-phone, but I really see the old skyscreen chronograph's going the way of obsolescence. Looks like I'll be spending some money for updated Magnetospeed stuff.

I have a Magneto Speed ... still haven't taken it out of the box! But the selling point for me was ... strap it onto a pistol (well a railed pistol anyway) at the indoor range and chrono away! Versus getting permission to put the chrono out in the bay.

However, I'm not sure how it can work on a semi-auto without a rail. Maybe they'll make an adapter that clamps onto the trigger gaurd?

Well, I can't argue that there isn't any ignorance here, but I also think your complete dismissal of the Magnetospeed, that it only performs as well as an $80 Chrony, is a bit of an extreme statement. There is no doubt in my mind that the 35P is still the best chronograph out there, and that the proof channel is necessary to have assurance of an extremely accurate reading from an optical chronograph, but I think the magnetospeed is capable of besting it with the right changes. If you add a parallel channel to the design, pretty cheap really considering the parts necessary, and run the signal processing at a little faster rate, you have the potential for a better system than the 35P. The last concern would be that the magnetospeed changes your barrel harmonics, that's not too hard to get around for everyone except the most accurate of shooters, it's not a difficult thing to change the mounting location of the sensors.

I honestly think it is silly that no company has created a better chronograph than the 35P yet, maybe it just hasn't been necessary since the 35P is accurate enough for even the most disciplined shooters, but I think that there is room for improvement.

I've got a magnetospeed coming soon, I'm going to start experimenting with it. I have the feeling that there are improvements all around on it that could be made.

There are better chronographs than the 35P. Oehler used to make a model 42 with acoustic targets and it will teach you more in one year than a decades worth of shooting. You can find them used for around $2000.

Orange
I already answered why the Oehler is superior but in case you missed it its called the proof channel.
The magnetospeed will give you a larger error but if that isn't important to you it will save you $100.
As Robert has posted you can't shoot groups with the magnetospeed because any time you add weight to the barrels muzzle you change its harmonics. That is how tuners work. I will post some pictures of your typical target rifles. One is a typical 22 a typical 600 yard gun and a typical 50 BMG and the magnetospeed doesn't work on any of them. Four typical target rifles.

[orangeusa]

I do apologize. I get wound up and it gets personal, when it should not.

[LynnJr]

Orange no worries here just trying to keep people shooting without letting them pay for stuff they don't need.

If this was a what to do thread I would tell them to put there cheap $80 chronographs on a 2x4 mounted inside of 2 buckets bolted together.
By doing that the set up time is seconds and you don't use the shades at all.
I am looking for a stick with all my pictures on it that shows the cave. We need 110 volts for our lights and most ranges won't let you plug in. This range is private.
