Disc depth vs All-metal depth

I would really appreciate it if any of you could explain to me why detectors detect targets at greater depth in All-Metal mode than they do in Discrimination mode.
One would think that this would not be the case with the new breed of digital detectors such as the Gold Bug.
Also, is this true with the Gold Bug? What if the Gold Bug disc is set low enough to only emit the low tone instead of actually silencing out any targets?
Thank you in advance for educating me.!!!!!!!
 
Actually it is true in all detectors that to filter it through the discrimination circuit you are going to lose depth.
 
My take on it, beep-digger, and I think this is correct, is that in order to decide whether to discriminate a target out or not, the machine needs to be able to first ID that target (to see if it falls in or out of your discriminated zone.) When the targets get deep, the machine can't get enough information from the signal to assign it an ID -- and so I think by default it is therefore not "seen" in disc mode. However, if you switch to all-metals mode, that weak "non ID-able" signal can be heard (which gives you that extra couple of inches of depth.)

That's how I understand it...

Steve hit it right on the head as I understand it too. All machines do this. Not all machines can work iron like the Gold bug pro and G2 can though.
 
Im guessing since the gold bug pro has 2 processor's it is able to Id much faster. Oh I must point out that the Gold bug pro has a ID mode in all-metal! The little dial meter thingy stays working on all-metal.I use this function in areas I need more depth for silver and seems to work.Just look at the graph in all-metal I figure its fairly acurate.
 
That makes perfect sense, Thank you all for sharing your knowledge....this forum really is a great place with all of you willing to share your knowledge and experiences!!!!

rockpup,

Help me to understand,

only the gold bug pro has this feature? Are you implying the G2 can't give ID on objects in all-metal? Aren't the G2 and Gold bug pro one-in-the-same? Thanks for your help - Jim

Steve,


Thank you for the clarification. HH - Jim

earthly -- rockpup was comparing the GB Pro and G2 to OTHER machines, not one to the other. Both machines (GB Pro and G2) are the same; he was speaking of both...
