Hey gang,
I was out this morning with the new FX Radar Portable Chrono and my Daystate Huntsman Regal XL in .22 caliber at my local outdoor shooting range. I just had my Regal recently tuned by Motorhead Tuning Services ( Scott ); and I am confident the gun is shooting very accurately with the new HUMA and all his mods.
This was my 'first' experience with set up and trying various positions and placements for optimum results using the Chrono. I have been reading a bunch of other posts and YouTube videos about using this Chrono, and I know opinions are "mixed" with likes and dislikes about trying out the new Chrono. This is my first Chrono so take everything with a grain of salt.
I spent about three hours at the range today shooting at both 25 and 50 yards with JSB 15.89, JSB 18.1 and Air Arms 16g pellets. I did lube all pellets, but I did not wash or sort them before using. Shot approximately 25 groups in total using all three brands of ammo above. There was some wind and I guessed about 3-5 mph and it settled down occasionally.
My goal today was more to "try out" the new Chrono and learn about the new device in terms of placement, proper height and positions. I experimented with height and placement along and in front of the DF Sumo LDC at the end of the Regal. I also changed the returns a few times from the default of 20%, but really did not come to any conclusions and need more experimentation here.
The Chrono 10 shot readings for the JSB 15.89 were averaging in the 850 FPS range with a variety of ES readouts for various shot groups. i.e., ES of 24, ES of 12, ES of 21, ES of 11. These were some solid 5-shot groups at 50 yards, but nothing spectacular. CTC average group size ranged from about 1/2 - 1" for the JSB 15.89.
The Chrono 10 shot readings for the JSB 18.1 were averaging 805 FPS with a variety of ES readouts for various shot groups. i.e., ES of 16, ES of 17, ES of 19. CTC average size again ranged between 3/8 " to 1 inch groups.
The Chrono shot readings for the Air Arms 16 grain were a pleasant surprise with the Regal. Had not shot this ammo before and I was surprised at the ES readings. i.e., ES of 5, ES of 7, ES of 9 for a total of (3) 5-shot groups at 50 yards. Had one group less than 1/2" CTC, and two that were between 3/4 and 1 inch. Interesting that the ES improved quite significantly downward from the JSB 15.89 and 18.1, but the CTC sizes did NOT reflect anything spectacular either.
FX Radar placement - I tried various heights and positions along the LDC and slightly in front of the LDC, and it appears to me that the optimum height is approximately 1-2 inches below the LDC and about 1-2 inches in front of the end of the LDC. In other words, 1-2 inches beyond the Sumo. Also, you need to make sure the Chrono is directly under the -center of the barrel. So, if you are using a Bi-pod and a back rest, you will "accidentally" move your gun slightly from time to time and you might be changing the placement of the muzzle or LDC in relationship to the Chrono. When I had this set up, it appears there was more consistency with the accuracy and I used the default return setting of 20%. I did notice from time to time, the Unit would NOT record a shot within a particular group. Happened about 6 different times, but it may have been me moving the gun slightly or just the unit itself.
All in all, I was pleased with the new unit. However, I would agree with others who have already replied about having some unusual and unexpected errors with this unit. Chrono placement is critical and you need to experiment with your air gun in terms of optimum height and positioning. I especially liked the portability of the unit, the easy set up on the new Manfrotto Tripod and how quickly you can begin shooting once you "know" the right height and placement!
Also, Centercut (Mike) mentioned this in his post, but I agree with him that you probably need to have a "trusted Chrono that you personally know is accurate and valid" as your primary Chrono. I think the kinks still need to be worked out on this Chrono and hopefully they will come out with a new and better application for iPhone or Android in the near term future.
I would welcome others' feedback on their experiences with the FX Radar Chrono, especially if that same feedback has not already been duplicated in several other posts.
