I purchased this item to help setup my bow and compare the reading from a program i purchased.
The program was giving me a 267,8 f/sec for my bow setup. So i installed this chronograph which is very easy to install .Then i took 4 ligthspeed 3d arrows same ones used in my program. Same length, same weigth and numbered them 1to4, shot them 5 times each and around 12 feet away from target.Here are my results.
Arrow 1: 258; 259; 265; 264; 268 F/S
Arrow 2: 267; 262; 269; 264; 264 F/S
Arrow 3: 258; 261; 267; 269; 256 F/S
Arrow 4: 266; 264; 262; 272; 264 F/S
Not Perfect but pretty reasonable and within the 2% claim.

I have been using this chronograph for a couple of weeks and find it to be exceptionally accurate. It is consistent with the conventional style chrono's I've used to check my current bow set-up. Very easy to use and carry along in your bow case. I'm very satisfied with the purchase.

Rated 5 out of 5 by shoot4peace radar chrono review
Great buy for the money! It does everything it says it would do, Make sure to read the directions it displays the 3 digit speed in two seperate screens, I didn't know this at first and almost tossed it into the woods. After reading the directions, and figuring out how to read the display it aint bad. The chrono is pretty accurate, it is jiving with online calculators. +/- 2% is equal to 5fps at 250fps and 6fps at 300fps, not realy enough to matter, but to get around this I shoot five arrows and average the speed. Most of my shots average 1-3 fps differance. This is a great peice of kit for the at home bow mechanic, and it will travel well. The only disadvantave is the stupid plastic thumb stud, it snaps in to an allen head, yeah I striped it off the first time I used it. It doesn't affect the funtion of the chrono, and there is very real allen screw underneath so I will still give it 5 stars.

Rated 4 out of 5 by marcc so far so good
I purchased the chrono for my own personal use and it works good. I like the size and the easy set up.
I just find that the speed readings are slightly different on every shot but might be due to a variety of things i must use it a little more to know defenitly

The device is easily attached to the 5/16”-24 threaded port on the end of most stabilizers. Sports Sensors, Inc. provides an extension rod if the archer does not use a compatible stabilizer. An adapter plate, also supplied, allows vertical positioning of the radar relative to the arrow flight path.
