Which brand/model is the best on the market?

Does anyone make a wireless unit that you can put the sensor remotely and not have the main unit in jeopardy of a poor judgement shot?

I don't need a lot of bells and whistles, just one that works reliably and has a low error and failure rate. Being just plain easy to use is a bonus as well.

I haven't used a chronograph for quite a while, and am pretty sure I didn't have a very good one. Got a Chrony at a good price, and figured it was worth playing around with for that kind of money.

But how do you know if it is accurate or not? Didn't seem to register every shot and the directions said to have it rather far away from the muzzle to keep the chronograph from clocking unburned powder particles. The arms were rather narrowly spaced, and I honestly was rather nervous I was going to hit the darned thing. All it would take is one flinch and the thing would have been history.

I did find out that you really shouldn't shoot sabooted rounds through it either..... That plastic sabot is no laughing matter if it hits something at 10 feet or so. Ask my Chrony about it.....

That was quite a while ago, of course, so I assume technology has had some rather large advances since then. But I assume they still haven't made one bullet proof, so due care is in order. I would think the more expensive the unit is, the more likely you are to shoot the thing accidentally.

Murphy's Law works like that.

I use a ProChrono, like it a lot. They're a little more expensive than a Chrony (run around $110). I'm on my second one, they don't stand up well to misplaced rounds. I also don't use it downrange anymore, keep it 5 yards from the muzzle.

For a rough check on accuracy, a .22 LR over it will tell me if it is operating correctly with the light that's available. I'm playing with using artificial light to take the variables introduced by clouds, sun position, etc. I can plug in easily since one of my ranges is directly out my back door.

I've built some shields for use with shotgun loads, also move it in closer for that. Results there are fair, with a lot of false readings due to muzzle blast.

Oehler's unit doesn't put the computer

downrange and I think that the PACT doesn't, either. Both run closer to $300 than $100. Fire some .22lr from a rifle across the screens. REgular "high speed's" ammo is a very reliable 1200 fps from a .22 rifle. Ditto, .230 gr ball is very reliable at about 820 fps, froma 5" 1911, given miliatary ammo.
