Has BPS capabilities
3 Digit Display
Ability to read ramping rates
You have to hold the unit on the barrel, no self support device,
I was doing some research on buying a chrono to use at home to setup my marker and tweak it prior to getting to the field to play. So, basically I found there were two varieties to choose from without spending a few hundred dollars, the Custom Chronograph Inc. and the Sports Sensors Inc, RadarChron. After reading the reviews on both on pbreview.com, I thought I would dig further. I wound up talking with George at Custom Chronograph, Inc. He confirmed what I had read online, that they do indeed make the X-Radar and they make the "Red" Paintball Radar metal Chrono that all the fields and shops use. He stated that they are working on a new, non-metal version of the red one because, "the red one is just too expensive" He also confirmed that the technology in the two products is nearly the same, but the red is more accurate because of the way the gun is rested onto the chrono. The inaccuracy in the X-Radar has to do with the fact the user has to hold the chrono, and because angles are everything with Doppler effect, it can make slight differences depending on where it is positioned on the barrel. The fact you have to hold the button the entire time was a result of the fact that people weren't holding the unit properly and blocking the wave front coming out of the thing (which is outlined by a rectangular box on the rear of the unit), so they stated that early versions didn't work very well, when in fact they weren't using properly. So, they make it such that you have to hold the button so you grip the thing correctly. And, it has the ability to measure BPS, including in ramping mode because it doesn't need to be reset between reads like the yellow hand held. He also stated that the guys that make the Sports Sensors Inc RadarChron (aka the yellow one everyone uses) was originally made for baseball to measure pitching velocity of a ball coming into a glove (see http://www.swingspeedradar.com/). This is why it only has a two segment LED, it measured ball speed in MPH. Therefore, to display a 3 digit FPS, they display the 100's digit first, then a delay, then the 10's and 1's digit second. Thus, to do another read, the unit must be reset, so the button must be pressed again. They adapted it for various other applications including Paintball. So, he stated that it is not nearly as accurate as the X-Radar (yeah, I know this is coming from a guy at Custom Chrono, but I believe him). In fact, he stated, get one of the Sport Sensors Inc (PMI is just a distributor) chrono, the X-radar Chrono, and the red Paintball Radar (you'll notice the bat symbol on the Paintball Radar and the X-Radar are the same) and get a high end marker that shoots consistent. Then, put all three head to head. He stated if he thought the Sport Sensors worked better than the X-Radar, give him a call and he would gladly refund my money on the X-Radar. II wouldn't expect that this is a standing offer from Custom Chronograph, but I thought that was pretty bold none the less.
The guys at Custom Chronograph were very helpful, informative, and took the time to answer all my questions honestly and completely. The product really helps me tweak my marker and is very easy to use. I have found that when I do get to the field, my marker chronos very close to what the field chronos show. I would highly recommend this product.
