I think there is a big misconception regarding the CTX and depth as it really isn't hunting any deeper then some of the other top of the line machines. However, where the CTX provides certain advantage is in its ability to separate and process weak returns. In reality the CTX isn't hunting any deeper then some of these other machines as this would require more power output. The CTX just has the built-in ability to boost and to process these traditionally weaker returns, if that makes any sense. It's not really an issue of more raw power and greater depth. At least this is the way I understand it.
thanx for the in-put big-scoop. If that's the case, then a lot of it boils down to ability of a person to interpret what they're hearing on their own machine. In fact, I almost DON'T LIKE it when a machine "boosts" faint whispers, or does too much controlling, boosting, enhancing, etc... Because then in a way, it's taking out the human element. I almost prefer to have the whispers, so that it's me (rather than a computer) deciding things.
The control is there on many machines, with signal boosts, "deep on", and so forth. But a lot of guys actually prefer NOT to use them (as counter-intuitive as it sounds). Because then you loose the human element of knowing deep versus shallow, etc.... at a certain point. Not saying that the CTX "makes them all sound the same" (Fisher Co. infamously did that on one of theirs, where all signals, no matter how deep, had the same exact sound/amplification). But ... just saying .... that I love the ability to grasp for those whispers.
When I tried the CTX, I couldn't figure that I was getting any more depth. But now that you mention it, it might be exactly as you say: That each one "got the deepie whisper", but that the CTX did it with more balls/louder, or whatever. But in the end, not actually *deeper*. The exception, of course, would be with the 17" coil. But sheeks what a PIA to be swinging around, trying to pinpoint, blah blah
