Ballistic Chronograph for Shooting, High Precision Chronograph for Arrow/Bullet Speed, with FPS/MPS Readings

this item was easy to assemble no problems. After reading the instructions 5 time I understand how the functions are to be used. the instructions are written poorly. I was up and doing FPS test on my air rifles with ease . make sure you read the instructions several times and understand how to switch into the 3 different mode to get into PFS modes after you turn on power the unit will cycle through the FPS, SU, --, modes press the square key at below the up and down key to get into the PFS mode, to get into the SU mode after power on press the Square key when SU is display, for the "-- " mode after power on press the square key when "--" is displayed hope the helps

Crap. Worthless. Barely registered any of the shots on the first day. Now misses almost everything (I'd say it averaged seeing about 1 out of every 20 shots I've put thru it, and that is even after I made a darkening hood to block out any outside ambient light). When it did see and register shots, it kept forgetting them, and storing them all in only the 1st register of the scroll log, so I lost the record of whatever ones it did manage to record. It hasn't been able to see any shots the last 2 times I've taken it out (well, 1 out of 36 then 2 out of 48 times), and those times it did catch, it displayed speeds that were just one quarter of the speeds I know the gun puts out. Frankly it turned out to not be worth the effort of taking it along to the range. There may be one star showing in the rating, but that's only because I don't know if zero stars would even post here as a rating, because I would actually give it a Zero Stars.

It's all right it's pretty good I'm on number two now

Difficult to set up, mis-reads every other shot. Errors out more than catches velocity. You get what you pay for. It's crap.

It works great until you are in bright sunlight. There is not enough shade above the light sensors for it to identify anything flying through it in bright sunlight. Next time, I will spend the money on a garmin, and just solve all my problems.

Good value and functional, accidentally shot my first one but I bought same kind again.

I've had a chronograph before this one is a little weird. The light bar on the top has to be screwed into the metal rods (there is a left and right side). The menu is not intuitive (push button when you see FPS to get it into the correct mode). Also the shooting area is pretty small compared to others I've used. There's some definite limitations but it works and for $35 you can't beat it.

*Edit 07/28/2024* Well it didn't last long. This chronograph began not registering shots after a few days of use. This got worse and now it only registers a few shots after powering off and on. Never seen an electronic device 'fade away' like this before. I'm going to return it and buy a Caldwell. *Original Review* I wasn't expecting much from this chrony, especially after seeing mixed reviews on the various listings which all seem to be for the identical item. The unit I received works perfectly and is easy to set. It successfully tracks air rifle pellets in my indoor shooting area under mixed fluorescent and led lighting. The measurements look reasonably accurate compared to another inexpensive chronograph. My only criticism is that a shots measured velocity displays only for a short period and then the unit goes back into a waiting mode for the next shot. I haven't read the directions yet so maybe this is adjustable? I just make sure to look at the display right after I shoot. The unit records the readings in memory so you can scroll back through them at your leisure. I like this chronograph, it does the trick and doesn't cost much. I will report back if there are any changes.
