QUESTION FOR MONTE:confused:

James, I'm not Monte, obviously, but...
I don't know why you say the GB-DP have "hardly any depth." Something may be wrong with your unit. NO, they don't have the absolute depth of an F75 SE/LTD, BUT they are very good, deep machines in my opinion -- as deep as most others I have ever used. My GB-DP will almost equal the performance of my Minelab Explorer SE Pro in my test garden, and that is very impressive. If you cannot get a good, solid, though soft, hit on an 8" quarter (even at 10" a quarter should be audible, though iffy, if the soil is good and damp -- ESPECIALLY in all-metals mode), then you have either a faulty unit or very difficult soil.
Feel free to PM me if you want more information, or results of my test-garden testing...

Same here with my GBPro. My detector hits with the 11" coil on a buried 8" quarter, 7 1/2" dime with the coil an 1"+ in the air. It is a very small quick quiet sound but I can hear it and I wouldn't miss it detecting. I don't know if your ground is bad or what kind of depths others are getting in bad ground. In my ground I am very happy with the depth I'm getting.

Try it with a nickel or small gold ring instead of dimes and quarters.

It's only a simple one as I translate the field response I get against other models I own and use, and int the ground environment I usually hunt in. Dave J. or someone with an engineering's state of mind and knowledge could spell it out in plain, UN-understandable technical terms. 
You ask, however, "HAVE HARDLY ANY DEPTH" and that can only make ME ask, what settings are you using, what targets are you referring to, and what ground mineral make-up are you hunting or testing them in? I know a lot of people who use a factory default 'preset' Sensitivity setting on a detector and don't increase it. Then they ask why they are not getting the depth that I might get with a similar model.
Let be clear on one thing: The G2 and GB-DP will get their maximum potential depth in an 'air test' if you increase the Sensitivity to maximum and reduce the Discrimination to the minimum settings. So, both are capable of achieving their maximum level of sensitivity and depth of detection.
Now, knowing how to see what the best is that those models do, you can use any other make or model/models, then adjust for maximum Sensitivity and minimum Discrimination, use the same test samples and move them across the coils center axis in the same position and compare the Sensitivity and Depth potential of the other detectors to them.
If THAT ks what you are referring to, and you're wondering why they don't respond with as much depth, as much audio signal strength, or maybe duration of response, then I can understand your posted question.
I like the G2, mainly with the 5" DD coil, but still, when I compare it, IN THE FIELD, side-by-side against some others makes and models, I consider the G2/GB-DP to have less depth of detection, a weaker audio response from mid-depth to the extreme they provide, and a very brief, short duration response.
So, if that is what you are getting at, then I can only say it is a combination of factors, such as:
Maybe the operating frequency; maybe the very brisk process used to generate a very rapid response and equally brisk recovery; possibly the VCO audio that peaks too quickly (for me); and finally, they just were not design to be a deep-target detector, especially on higher-conductive targets such as copper and silver and clad coins.
We have to pick-and-choose the detector and settings and search coil for our individual site needs, be it ground mineral make-up, or density and type of trash present. I like the G2. Using the same search coil set, I prefer the Omega more than the G2 for all-purpose hunting. One of several reasons , for me, is that the Omega is better at depth, hotter on higher-conductive targets, and it can use the concentric coils and I like the elliptical 10" it comes with.
Too often I see people hunt and hunt and hut an old park or school just knowing that, because of the age of the site, it has to have older coins ... especially silver. Might they find a missed stray older coin? Certainly, but most of the good stuff is simply GONE! Those of us who hunted early an a lot, like me from 1965 and every opportunity I possibly could, found the older and better coins and thinned down some lost during the transition that lasted through maybe 1985.
There, a short (for me) and simple answer. But I agree, that while I like my G2, it is NOT what I consider to be a depth monster, regardless of the coil attached.
If I missed your point in the question, clear it up for me.

The Teknetics G2 and Fisher Gold Bug DP are supposed to have the same internal circuitry and both sport the same 11" DD coil. Therefore, I presume that under 'average' conditions, they will show similar performance.C.J.M. said:

Possibly, but I seldom like an after-market coil. It doesn't matter who the detector maker is, I prefer to use a factory coil from the detector manufacturer. Also, I am not a really big proponent of 'depth' because too often people want to get better depth and find deeper coins in places that are too littered to detect targets below the trash, and for the simple matter that in most places there just aren't deep targets.C.J.M. said:

James, I've read all the responses so far, and there isn't really much to add, except, if you are able to use the G2/Gold Bug Pro in all metal mode, the depth capabilities will increase. It is not always practical to use a detector in the all metal mode. I have used my Gold Bug Pro, with 11" DD coil at the beach and I noticed a significant loss of the number of targets detected when I switched to discriminate mode, and then when I switched back to all metal, I was getting targets again, and these targets (coins) were deep, and compared favourably with depth obtained with multi frequency machines, in dry sand. I made the mistake of loaning the excursion, and now it is the only detector he wants to use when he comes out with me. I'm just adding this post to the others as it reflects my experiences with the GB Pro, and there may be occasions when you can use all metal mode. HH

I would echo Furious T's sentiments...when I am using the 11" coil, and running in all-metals mode, my GB Pro will hit targets AS DEEP as I can with my multi-frequency FBS Minelab Explorer. That is no exaggeration either -- I can hit a 12" quarter with my GB Pro, buried in my soil, in all-metals mode with the 11" DD coil (which is the deepest coin I have buried in my test garden so I can't comment on targets any deeper than that...!! 
) Many times, I CANNOT hit this coin with my Explorer, but I CAN with the GB Pro, in all-metals mode...

Do you get any bars at the top on the deepest targets in all metal? I don't with mine.

Have not checked that specifically, Rick. I will...
I seem to have a general feeling (not well-tested) that I get the ID bars up top to about the same depth as I get a numerical ID in disc mode. I can hit targets in disc. mode with no ID number, and I'm thinking the deepest targets in all-metals mode ALSO don't have ID, but I will check for sure. My guess though is no -- deep, deep targets do not give the ID bars up top, in AM.

In all metal, I use the cursor on the top of the screen to give me a rough idea of the ID...and it does help...in my last post there is a piece which doesn't make any sense....i.e. it should read " I made the mistake of loaning the GB to my son on one of our excursions, and now it is the only detector he wants to use........Happy Christmas to all.

Since I use the G2 the holes are deeper than in comparison to my former Fisher F2. And that only in Disc mode, cause it is too trashy here in Germany near a big City.

C.J.M. said:WHY IS THAT THE G2 AND MAYBE THE GB-DP HAVE HARDLY ANY DEPTH?MOST FISHERS HAVE LOTS OF DEPTHIS THERE ANY OTHER COIL THAT WOULD HELP?THANK YOU.----JAMES
Monte is right, And I agree, but I think a lot of people hunt to quick and fast and miss a lot of ground. Coil movement and the speed will help depth on your detector. I have dug in Georgia, a Dime with the 5 inch coil and dug 6 1/2 inches in the ground. Now I was swinging the coil real slow and moving the coil about a 1/2 an inch at a time forward over lapping my swing.
