Lonewolf54 translated the Chinese instructions to English and put them on this thread.
What Page and Reply # has the English instructions for the clamp-on model?

Is what i see..  heck maybe more in all these pages.

Heck now i wonder back when i f i got the right one ....lol...?

I have been looking back thru this old thread for answers to basic question with no luck.
Will the clamp on model work on a break barrel with open sights such as D34 and clones or will the sights be in the way?
There are different stores and prices on the site. Any recommendations on the best store?

 I sometimes have to mount them upside down, makes it tricky to flip n read quick LOL but you can go back and get the string.

[MisterAP]

I’ve mounted it at an angle and it was fine.  Easier to read.

With a break barrel, I don’t know if any position is good unless it securely affixed.  I also haven’t used it on a break barrel.

[A moron]

I ise ot on a r9 and a gamo with the large baffle each with a front sight/ globe.

But i just set it on the bench without the ubolt / clamped on and rest the barrel on it properly and shoot .

I dont care about hitting a target just to get a shot string. 

Ill also bet on a springer bolted on the tecoil shock would damage it  just as easy as a cheap scope.

So i just dont mount it.     I did at first but then that part clicked after my first string new then never again.

[MisterAP]

Yeah that’s probably the best suggestion for springers.  Maybe even secure it to the table.  I didn’t do that with the big bore and wish I had.

I got a Caldwell for $80.  I figured even if I fix/get a new one, it is more fragile and hard to mount/use on some rifles and pistols.  Sometimes I do want to see accuracy while measuring the speed.

[Nick horse]

Thanks.  I was thinking that about just resting the barrel on it. I assume the muzzle only needs to be flush with the mount.   
These have been out awhile. Do other chrono models have replaceable batteries? These look like a good deal but I guess I’d be asking if it might be worth it to pay more for one with a possibly longer lifespan.  I have never owned or used one. Tried chrono connect with no success.

Ya, i can see that of your gun is adjustable on the fly.  I guess of you shoot a string and ot checks out and your hitting the bullseye  its the same mounted or not ... I guess 🤔

To the batteries being replaced i dont guess ive seen anything on that.   I guess ot could be soldered in  or a can't get in the usa.  That's my luck  none to be found anywhere..

Youd think someone had took it apart to see and posted it somewhere .


For what it is and so far worked for my need ay $30 its fine.

Now if was a big shot air gunner and had several guns  or did reviews  id just invest in one that  has the options like Bluetooth  and thrills,  but backyard just to keep check on seals or what not  and run a 5 or 10 shot string  every few months  it does that job fine.

If you can afford it I recommend you get the $80 Caldwell one. It's nice to be able to chrony and shoot for accuracy at the same time, and it's also very nice not to have to manually record your shot strings if you want to analyze them in a spreadsheet. Last time I had my $30 one out I also noticed I had to wait a few seconds between shots for it to record properly, which can get annoying if you are shooting long strings or rapid-firing CO2 guns. If I had it to do again I would have just started with the Caldwell.

The Caldwell uses a single 9V battery, which will likely be more expensive in the long run, as the cheapo is rechargeable. It probably wouldn't even be worth it to replace the rechargeable battery given the cost of the unit, but I doubt that would ever be needed unless you are using it a whole lot.

I think the price fluctuates a lot on the Caldwell so maybe do a camelcamelcamel alert.

But at the end of the day, the $30 chrony is better than no chrony!

Its not a bad deal and amazon has had like one day sales as low as $64

Just what i see better have a android device 

Apple looks to be near no support.

A guy here just got one and i guess ipad aint a go.. guy with new hw80 posted here.

Anyway somthing to look at before you buy. 

That other brand may be better supported on a device Bluetooth?  Just costs more ..  (?)

[MisterAP]

Here’s the battery. It is unmarked.  Looks like a typical small device Li-ion battery.

Thanks..

I looks hard wired in  ....


Then would not be surprised if a replacment battery delivered cost as much or more the the whole unit did ...lol...

[MisterAP]

Yeah.  I suspect with typical use, especially if it is frequent enough to keep the battery at the half-charged level, the thing will last a decently long while.

Can’t recall when I got it, but I think at least a year so far.  Course, now I gotta solder back the disconnected -ve lead before it is usable.  I held it to the contact and it still turns on fine.

Well hope it was not too much trouble then to give the picture...


Mine s year or so old and i dont use it much, bit i do hook ot up for a short time as i go to keep it up   .theres no charge indicator bit the light on the cord thats on all the time anyway..

Heck i may just use it today just to use it...

[Nick horse]

I have considered the Caldwell Units. But looking at posts where errors were common on read outs and people installing them inside with special lighting so they work better, well,  I just go outside and shoot for fun. The bolt on the barrel seem easy to use, help me find a problem quicker have fun seeing what velocity is and a bargain so I may try one. Can’t believe I never saw these before. I would still like to more about them all. That’s for the advice and input guys.

"  I just go outside and shoot for fun. The bolt on the barrel seem easy to use, help me find a problem quicker have fun seeing what velocity is and a bargain "

That sums it up on mine and my use of it...

Ran a string yesterday just because .  Did it's Job .  All i ask.

Here's a review on the one I bought. I clamp on barrel. Glued some foam padding where barrel rests and threaded plastic tubing over loop wire. There's a thread on GTA converting the manual to English. It reads in MPS so has to be converted.

[Nick horse]

I Ordered the clamp on model thru WM.com. $35.90 with tax.  I have a new spring and seal I got from Mike FDA for my Blackhawk which has a burnt seal and spring broke at the 2 rear coil.  I am glad I hadn’t gotten around to fixing it yet. Now I can do a before and after velocity string. Thanks again guys.
