I'm reading the comments here about the Labradar, (I do not own one, I've been using an MS V3 for quite a while now) and I went to the manufacturer's site. It;s Infinition and they are located in Trois-Rivieres, QC, Canada. They have been in business since 1996 and they do Doppler radars, lots of them. It appears that the Labradar is the only consumer-type product they offer, all other products are for defense industry purposes.
They do mention the LabRadar and they have a few links to the latest specs and software, unfortunately these are dated 2018, 5 years ago.
Speculation warning: I can't help but think that the Labradar device was someone's pet project at Infinition and they sloughed it off to a distributor so as to not be distracted by supporting a consumer product. Of course, I could be totally off-base here.
Anyway, Garmin has a huge catalog of electronic consumer products and the Xero would be just another such product. They know how to support consumer products.
