How far do you have to be from the device for accurate reading, like for a 9mm for example. Thanks!!

this shooting chrony can be read off the bench from 10-15ft with any caliber of gun or rifle

I do not have the instructions with me but if I remember correctly you place the chrono 10 feet from the muzzle with center fire handguns and rifles. The instructions that come with it tell you exactly what to do.
1399589
If you are shooting ammo that has a velocity less than the speed of sound, be careful not to set the chrony too close or you will only measure the speed of the muzzle blast (which = speed of sound). Such was the case with my 45ACP shooting mild 200gr semiwadcutter target handloads. Everything was at the speed of sound until I backed the chronograph out to about 15 feet. Only then was I able to measure subsonic velocities. If your ammo velocity is greater than the speed of sound, then it really doesn't matter if you set it closer, since the bullet reaches the chronograph before the muzzle blast can affect the measurement.

Not too close because muzzle blast will either knock the unit over or at least cause an erronious reading. The length of the cable controls max distance of 5 metre so 3 - 5 metres is ideal........enjoy

The further away the better (10ft max due to cable length). You will see both the device and the target easier. If you have a scope on your gun, turn it down to the least magnification. Do not shoot if you can not see your gun sights, your chrony and the target. They must line up. Take your time and good luck.

I think this item is very durable. But the reading is not accurate. I use mine in the shooting range and according to my sound level meter the voice of the shooter is louder than the gun shot.

Mounted this on a tactical shotgun and it may be about a foot from my eye. I don't have any problems picking up the dot. Actually I think it is easier to use further away than closer.

You can but keep in mind the accuracy is not survey quality. Best accuracy I've seen with it is +/- 10 feet.

Range and sensitivity depends on many things, the most prominent being the total RF power, orientation and the sensitivity of tags. Having said that, this device operates at very low power and for most tags that would be read from 6-8 feet on a regular RFID reader, this device will read them in less than 1 feet. With a less sensitive tag, you can expect the range to be a few inches.

if there is an item ( my case a deer or a target ) it is very accurate but a friend was looking for a distance to a spot in a field and it had nothing to bounce the signal off so it wouldn't work. the item has to be vertical and substancial.

If you are talking about 300 meters. I could not answer that question. Mine is set up for 100 yards which is plenty good in the state of Indiana. It also has a knob for each 100 yards to adjust after the 100 yards by twisting it 1 time for each increment after the first 100 yards. Seems to be fairly accurate for the price. Overall deceit value.

As long as it reads 300 to 400 outside it gives me confidence that it is fairly accurate. And it Alway has stayed in that margin outside. In a dark room you can see the infa red pulse every few seconds and seam to adjust corispodingly. Hope that helps.

You'll need to zero the red dot/green dot on the distance you're comfortable with. Me, it was 100 yards. There is no magnification and is easy to pick up.

I am not impressed with this product...the distance quoted just is not true. Personally, I would look for a different device.

James...think of it as a cone emitting from the barrel of the temp. gun....the farther away your target is the wider the cone gets...thus the larger area that the temp is taken. If you are taking the temp of a wall 10 feet away, no problem because the wall will probably all be the same temp...however if you were taking the temp. of a small area on that wall...you would want to move closer to get an accurate reading...the cone to distance ratio is 12:1 if that is a help to you. A target 8 feet away will measure temp. from a circle of about 12 inches...and I have found the target distance to read area stays consistent throughout. Hope this helps...

The display is large enough to be visible form sitting on the bench with the unit 10 ft away. Also you can always walk up to the display and hit the buttons to view each shot, each string..etc. I have tested shotgun slug rounds, .375 H&H; , .458 Win Mag, and 40 SW handgun calibers with no blast issues and the chronograph displayed velocities for each with no hiccups. In the event that there is an error there is a delete shot button that will not include the specific shot in the string calculations. Its really a superior chronograph as compared to others currently available. Hoped I answered your question.

Make sure you are not picking up something behind the target. I have never had any accuracy problems with mine. Also, how do you know that it is 100 instead of 90? This model doesn't have gps btw.

about 10 m at the out most distance from the sensor. however angle of the sensor and others can reduce the range

It really depends on the size and power of the reader. I know I've seen some industrial units read a couple feet away. I haven't used this RFID ME reader in a few months but I believe it can read about 4-5 inch gap (maybe).

These are not perfectly accurate, just close. So I start at 50yds or at 100yds and go from there. Then I dialed it in with real ammo, they just save a little ammo at the start, but there not dead on accurate.

The probe extends into the barrel 8" or so.There is an o ring sized to your caliber on the tip to center the device in the barrel. The other end is tapered and has a strong magnet to hold center.Any deviation would be extremely slight.Getting on paper at 100 yards/meters or more is not an issue.The laser is very bright.i have effectively used the unit in full daylight at 100 yards.The trick is to have a buddy shade the target face.
