I'm following this thread with some interest, as I have the new TBC as well. It does have several drawbacks, which should be fixed in the next few weeks, hopefully!
The data stream out of the unit, does report all of the data you see on the TBC screen, including the various velocities at the selected distances, averages, means, BC, etc. The shortcoming here is, there is currently no app to receive the data, and massage it into a usable form. A sample of sorts is described in the manual, but not available.
The latest firmware update does include the RA4 ballistic profile. If yours doesn't have it, update it. Since it (RA4) is designed for the 22LR, it will fall short exponentially starting at about 100 yards, depending on the ammo you're using. Hopefully, the ST4 and other common ballistic profiles will be available soon.
You cannot use two of the devices at the same time, if their radar beams cross. Where they do, depends on separation, local conditions, etc. In any case, don't expect it to live with a few others at the range! By the way, the same is true of the Labradar. I can't use mine and the TBC at the same time. While I'm on the Labradar... The microphone is as cantankerous as the FX chronograph is. In other words, spotty. And the Labradar will calculate the BC, but lacks the proper BC profiles as well (none specifically for pellets or slugs).
It will see a .177 out to about 75 yards, perhaps a bit further in a decent ambient. But remember, the minimum is 400 FPS, albeit will detect a bit lower than the spec.
Battery wise, it will run about twice as far as the manual states, if you remember to turn it on standby when you're reloading, or setting up new targets.
