I'll be very curious to see the price point, and a bit of a broader look at the capabilities. Labradar comes in around 550$, and ELUs have complained of a variety of shortcomings some software some hardware. Overall though results have been positive, so FX would probably have to slot in considerably below that price point to gain market traction.
I have other questions too like what the working FPS range is, if it tells you at what distance the velocities it gives you are, and what sort of formats it outputs the data in? Will it read bullets, making this a useful little multi-tool? Can it read velocities at multiple distances giving you the data you need to generate ballistic coefficients?
And my final big request is can software be written that'll allow this to spit the data out into a spreadsheet? I realize there may be technical challenges to doing this, but all the complaining Labradar endured was largely because ELUs had no way to analyze the data beyond a few pre-set metrics. As a result it really wasn't as useful for things like load development as you'd want in a 500$ instrument since you'd have to scrawl all the information down manually and put it into your own spreadsheets.
It is just my opinion, but Doppler radar chronos are kind of a specialized nerdy tool for us special freaks who really want to crunch numbers with our guns, they're probably not going to be as easy a sell as the simple gated chronos which can be had cheap. Thus catering just that one feature, outputting into a spreadsheet, would certainly please me and probably please others like me who want to do more with the numbers than just look at averages.
