Are these two detectors the same except for the Vaquero having a gb and the Cibola not? Just curious because I come across users who have modded their Cibola with a GB modification. Doesn't this essentially turn the Cibola into a Vaquero? Why do this instead of just purchasing the Vaquero in the first place? Is the GB mod easy and cheap enough to do to warrant purchasing the Cibola then modding it yourself or having someone do it? I'm in the market for another Tesoro and besides waiting on the release, field tests and reviews of the new Outlaw, I am considering the Vaquero and for a savings, maybe even the Cibola for my land unit.
