Arrowspeed Radar Chronograph
Easy to use, but not a great value
I almost returned this product the first time I tried using it. The unit turned on, but did not initialize as expected. The operating instructions indicated that the problem could be caused by a faulty battery connection, which turned out to be the case. I had to manually bend/adjust the terminals to fix the problem.
Since resolving that issue, the unit has worked well (although I've only used it a handful of times so far). It's easy to use and yields consistent readings. The fact that the LCD only displays 2-digits at a time is a bit annoying. It perplexes me why a device designed to register arrow speeds between 150-450 fps was not built with a 3-digit display!
While it does give accurate readings, I don't consider it to be a great value for the money when compared to other options out there. I have the Bowometry app on my phone which is just about as accurate, plus it has a whole host of other features at a fraction of the cost.

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.

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.
