Czech company Dronetag debuted what appears to be a capable add-on RID module named "Dronetag BS". The product name as a not-so-tongue-in-cheek assessment of their opinion on the globally expanding requirements for RID. The product was shown at the Xponential 2023 conference in Colorado last month and, if ordered the day of the announcement, was pre-order priced at $49 after which the price went to its "habitual" price of $89. Weighing just 0.105 oz (antennas included) with dimensions 0.66 x 0.55 x 0.19 in, it purports to satisfy all FAA requirements. It's unclear when the product would be available, but FAA requires RID starting Sept 16th of this year.
Obviously the $49 price looks extremely attractive, but that price had come and gone by the time I ran across the news. Too, I'd like to see some user evaluations under real world conditions before buying any new product, particularly from an overseas company with which I am unfamiliar, before I handed over $89. Ken Herron did a YT video on a couple of after market RID units including a more expensive module from Dronetag and he seemed impressed. I hope competition will ultimately lower the price points of other companies' modules so those of us with legacy drones can keep flying without having to abandon them. Time will tell.
