FX Wireless Radar Chronograph Review/Opinion Video

Jump to latest Follow Reply
very well said I don’t know about lots of you guys but I am on a fixed income “forced retire” and $200 to me is a lot of money, I would also expect something I pay $200 for to work as advertised, I don’t want to get into “well if ya just do this, or do it this way, just a 1/4” back and a tad to the right it might work”. I wanna just set it there and have it work, like my caldwell does. Like I said in a previous statement I will just wait for FX wireless chrony V2

I'm not sure why Giles deleted his post. It wasn't offensive at all and simply asked for more details on how I collected my data. I've spent all morning making another video to show him my testing methodology. I did the exact same thing to collect my original data. Maybe others can take a look at it and point out what I'm doing wrong. Having a discussion revolving around hard data is much more useful than subjective claims of "It works/doesn't work" for me....although I definitely listen to those as well. I think a more data driven direction was what Giles' post was really wanting the discussion to go towards.

Lots of effort on your part and people will appreciate that. The cost of this unit seems reasonable (to me) if it works well but is still a noticeable amount as some have noted. Unless people can have confidence in the units functionality then that is an issue and at this point that seems questionable. Personally, I hope they get it resolved because I would buy one if it seemed consistently easy to use. Thanks for your efforts.

The main problem with mine, is trying to get it to work, period. VERY sensitive to where it is placed, and when you finally get it to where it wants to work, it will still miss shots. VERY finicky, and a big waste of pellets, trying to get it to work. I'm back to my old fashioned ProChrono with lights. It works, FX, no!👎👎👎

However, I might have a slightly better opinion, if I had been given my FX Chrono for FREE like many of the good review people.

From an FX-USA post:

Actually the FX Chronograph and the Carbon paintball chronograph are not the same unit. Long story short, we essentially collaborated with that manufacturer, worked with them, beefed up the internals so it would handle PCP airguns, improved it, and perfected it. The older paintball unit just isn't the same (which is why you haven't seen guys really use them the last couple of years since they have been out). Hope that clears things up a bit.

All the guns that I have except one has the DonnyFL Sumo on them. That one exception is the Edgun R5M Long. I can't get the FX Radar to work on it to save my life. Probably because the air tube comes almost to the end of the shroud … and who knows, maybe that little electronic gage in the air tube throws the radar out of wack. Even tried placing the radar under the front end of the stock … wouldn't even register!

Just from my own observations and I am by no means an expert, you need a shroud or LDC that sticks out in front of the air tube by at least 3 inches to place the radar under. It needs a distance of 1/2" to 1" clearance directly underneath the moderator. It MUST be lined up very closely with your barrel and your target so it can catch and record the pellet in flight. For those of us who usually shoot off an old wobbly table … it is easier said than done … but it can work. Just depends upon how much frustration you are willing to put up with.

When I was able to get readings from the Edgun they were anywhere from 850 to 920 with the JSB 33.95 MK2. The other guns I have seem to work pretty good, just place the radar headed the right way, about half way down the Sumo and an inch below it. I shot my Vulcan 2 Tactic yesterday and it was running 900 to 909 … moved the radar to shoot over it with the Cricket and it was going 908 to 895 … put the Vulcan Tactic back on it and this morning and it was shooting very close to the same range it was the day before ... 898 to 910 and the Cricket was going 893 to 910. I don't know, time of day, humidity or thickness of the air.

I was trying to get the Edgun to shoot in the range of about 850 fps with the MK2s but every time I would move the HST the radar (when it would give a reading) would jump sometimes 40 to 50 fps with only a 1 click turn of the HST. 

I haven't tried the Wildcat or the Impact yet, but would expect the results to be similar to the Tactic and the Cricket … they are all in .25 cal … have no idea whether a .22 cal would work as well.

One thing is for sure, the placement of the radar is everything

As of this time, I am not sure if I will keep it or not … glad I still have my old Pro Chrono

I'm sorry if I wrote something bad. The results are approximately similar because they are two different devices and different measurement methods.

1)
Small devices are sensitive to an angle.
2)
If the distance from the barrel is too small - a noise, vibrations, may disturb the measurement, especially when you use high power rifles without a sound moderator or the radar is placed before a barrel.

OK....think I'am returning my recently acquired FX Pocket radar. I just finished a couple of hours with the FX and three different guns and a lot of pellets !! I have to say the FX is erratic at best and not trustworthy. My shot were fired from a Prod in .22/Mutant Shorty in .22 and a Benjamin 1701p in .177, I started all guns with the full allowable load of air. I never let any of them fall below 60% or so of total fill level. In a shot string of 8-10 the difference in fps would vary from 7 to 14 fps. Several times the first shot or two would be 7-10 fps slower than the rest of the string. My Caldwell was not nearly as handy but quite a bit more consistent. I had hoped for more but alas I was wooed by hype. I hope my return is not painful.

Well, I got mine out to try again today. Just for giggles, I set the sensitivity to "6", and it appeared to want to work for a change. Got all excited, and started shooting strings, but then it started missing shots again, and finally wouldn't register at all. Tried moving it around, etc. etc. no luck. I hate returning anything, so I'll toss it in a box somewhere, and hope for a firmware upgrade in the future, that "might" make it usable. Such a waste.👎👎👎

A nice presentation... but if the distance Y of the barrel is higher, an error is higher too.

When the XN ( max. operating distance) is short, a frequency of received signal, strongly depends on an angle.

An example 1 (Air Force Texan, assumed X, Y )
Y=4 in
X=20 in

TRUE_SPEED= 953/(cos(atan(4/20))) = 972 fps

An example_2 ( FX Dreamline, assumed X, Y):
Y=2 in
X=20 in

TRUE_SPEED= 909/(cos(atan(2/20))) = 914 fps
