I have been using a chrono that is designed for airsoft. Works OK until I got the Huben K1 . The chrono displays "time out" for every single shot. I guess the velocity may be too high for it to measure . May I know if there are any compact chrono that is reliable out there ? I don't need any features but just displaying the velocity and energy. Thanks in advance.
compact chrono recommendation
- Thread starter airgunfans
- Start date
You only need the velocity - free download software Hawke chairgun pro lets you select pellet make and type and automatically gives the energy after you enter the velocity into the software
I use a cheap shoot-through velocity only chronograph I got from AliExpress for equivalent of about $42 delivered to UK
They are normally listed as "velocity meter"
A lot of these cheap meters only have 1 IR transmitter and 1 IR receiver - I got one with a row of 6 transmitters and 6 receivers - you can see the 2 different types by searching AliExpress with "tachometer initial velocity tachometer e9800 X3200"
The IR (infra red) chronographs are not light sensitive like some of the expensive shoot-over chronographs

They have an internal re-chargeable lithium battery - may get USB charger cable, or a charger - depends on the store you buy from
Usually come with a mini-tripod

Thanks SteveUK. Very close to what what I am looking for. Just wondering how it performs ? is it prone to be affected by the puff of condensation coming out from the muzzle ?

Give Combro a try:
https://www.combro.com/
not expensive, and designed for air rifles. It uses a rubber band to attach to the end of the barrel. I've got one and it works great, service is great, etc.
You'll need the Combro, and I'd advise getting the Bore Guide. Total is about 54 Pounds Sterling.
Only thing to look out for is the caliber. if you shoot over a .22, talk to Robyn before placing the order. Make sure it's OK.

I use mine with my .25s without any problem. I also purchase the hook up for my laptop, but you need to have some computer experience to make it work. It will require a USB to Serial converter. The program is pretty archaic as well, but it does log your shots. Without the computer, you have to clear the reading on the Combro manually after every shot

No, not effected at all - that's why it's designed as open on all sides - for the air blast to escape, and the distance from front sensors to rear sensors is 3.5 inches, so no problems - the usual shoot through ones have just a hole in the case, and they are claimed to be effected by muzzle blast, as it's funneled across the sensors - but that claim is made by the makers of the open type, so may be biased - but then again they may have tried closed design and rejected it
Anyway, I'm happy with mine as it's a large opening to shoot through, and Infra red transmitter and receiver sensors unaffected by light levels

Just found a seller selling ones like mine for $34.75 shipped to USA - cheaper than I paid for mine
aliexpress .com/item/Muzzle-velocity-tester-valence-e9800-X3200/32810999374.html
Anyway if you search AliExpress for "e9800 X3200" you'll see lots of different types

There are alot of cheap chronies on aliexpress , but whatever you do, don't buy this one:

While it seemed good, it didn't hold up to closer inspection (ie, direct comparison to the Caldwell G2)

From the manual "Pressing and quickly the RST button places the cb625 in READY mode. This means that the infrared lights and sensors are switched on, and it is waiting for a pellet. Always check the display at this moment" You have to press that button after every shot, I didn't say it didn't store the shot. If you are hooked to a computer, you shoot away, and it logs to the computer.

I'll have to disagree. I use it quite frequently when I want something fast. It also computes the average, hi/lo and power factor if you put in your pellet weight. I think it is a good unit for the $66 bucks I paid.

The Combro is a good inexpensive unit that simply works. What more can you say? It's also great for the range as you can put it on your gun, and check your shots regardless of "Cease Fires" and all the hassle of setting up a regular chronograph. I have the Caldwell, and it's got some serious advantages, but for a compact unit you can take with you, and cheap to repair, I've been favorably impressed. I'd buy one just to keep in my range bag. Service is great too. . . . .

As for the Combro cb625, my plan is to try this:
Android , Windows & Apple MAC - cb 625
Download the free Chronosoft app and just use it on my android phone. Looks to be a compact setup that could be beside me when bench shooting and negate the hassle of resetting after every shot.

I've been using the Combro for a couple of years. It works fine but is a P.I.T.A. having to reset after every shot. It sometimes gives wild readings when the speeds are over 1100 fps. so it's no good for rimfires. Changing the batteries usually makes it more reliable. I haven't bothered with the app because I don't have the cable. I saw one of those cheap Chinese ones on Smeliexpress for $25 USD and thought what the heck, It's not going to break the bank if it doesn't work. It turned up the other day and the instructions are in Chinese. After putting it on charge for a few hours, I put a few strings through it with different pellets. It worked flawlessly and returned readings consistently the same as the Combro. It's the type that clamps on the end of the barrel and needs to be mounted horizontally to avoid the LED lights blurring the scope picture. Without readable instructions, I couldn't figure out the energy weight inputs or strings and it only reads in metric but that isn't a big deal. Also, there is no light to say if it's charging or not but it is supposed to have overload and overcharge protection. For the $35 AUS I paid for it, I'm very happy. I just need to find a Chinese girlfriend to translate the instructions.
