Jeff, WOW. OUTSTANDING digs! They really are...
BUT -- the MOST IMPORTANT thing I want to know -- given that you are talking "one-way signals" == are your LIMITS settings (expecially your "upper limits"). I don't think that a good many folks realize how adjusting your limits settings (up, or down) will ENTIRELY CHANGE the way a "mixed signal" target will report/ID. You can ABSOLUTELY, and VERY EASILY, change a one-way signal, to a two-way signal, JUST BY RAISING YOUR LIMITS BY A FEW DIGITS. I know you know this, Jeff, but it's one part of the Manticore that especially for Manticore users who don't have prior FBS experience, may not be fully understood. Those without past FBS experience will likely will not grasp, initially, the FULL importance/implications of limits settings, and what they do...
Said a different way, you can have two guys, both hunting Manticores, with the EXACT same settings, but one with their upper limits set "high," and the other with their upper limits set "lower," and if those two hunters interrogate the VERY SAME TARGET, and then compare with each other what they are hearing, one may hear 100% iron grunts, and the other may hear 100% non-ferrous high tones. PROPER LIMITS SETTINGS are critical, and anyone who wishes to master this machine's ability to "unmask" will really need to begin to wrap their head around exactly what limits settings do, in this regard. I venture to say it is even MORE important, from an unmasking perspective, than recovery speed. You can set your recovery speed as high as you want, but if your limits settings are not adjusted properly, you can entirely negate whatever advantage that high recovery speed may have otherwise offered you in terms of improved unmasking...
With this said, the factory settings for limits are sort of "in the middle," and that's "fine." All I am saying is that if you begin to deviate from there, just know that you will entirely change the way mixed targets will report...and I feel strongly that it is very important to understand the relationship between adjusting limits settings, and how the target response will change IN RELATION TO that adjustment of the limits setting.
