Hi — VABIRA team here.
Thanks for mentioning VBR-Aqua and the KalamazooReefer review. We’ve been going back through older community discussions like this because there have been several sensor generations over the years.
The current VBR-Aqua is the latest production version. If anyone is looking for the current model, it is now available on eBay — search VBR-Aqua PAR Meter, item 306372021071.
Happy to answer questions about the current sensor, PAR/PPFD, DLI, B/G/R readings, or underwater measurement method.
