Ves obtained a lot of gains from his brief two-hour study. He learned a bit more on how the stealth crawler managed to hide itself from detection.
More importantly, however, Ves also managed to deduce the weaknesses of this application of stealth tech. More than that, he also deciphered some of the holes that circumvented these means.
These loopholes not only worked on the stealth crawler, but any other application of stealth that worked on the same technological principles. Ves guessed with a high degree of confidence that the infiltrator suits that Calabast and her operatives made use of shared the same principles!
As long as Ves tuned his stealth detector gadget with settings that exploited these loopholes, it might very well be possible for him to detect Calabast and her invisible bastards when they thought they were sneaky.
