The positioning of knob on left side may indeed cause right hand users to inadvertently move the knob when it contacts their body, etc. Here’s a short video I did with a cheap fix. Enjoy.

A local Craigslist ad had this for $100. I contacted the seller and after some conversation he indicated that in fact he had no idea if it worked or not - it was him moms - had been sitting for decades. He lived 50 miles from me and I an wary of driving much in this pandemic. I asked about the batteries and he looked - they were a mess he said. He said that he would probably trash it and I asked if he had any reason to drive my direction anytime soon. We agreed on a spot halfway and I offered $25 “sight unseen”.
The original recargable nicads were in there - a mess. The battery clips (a known issue with this machine) had a bit of surface corrosion which I filed away and some solder repairs which looked solid enough. 14 AA alkalines later and it works a bit squirrelly, but seems to be fine. Air tests at 9” or a bit on a quarter on the ground in discrim and 12” in AM. The tone ID works fine and the meter seems to under-read a bit but is consistent.
These things weigh a ton and this one is an original factory hip mount - a strange shelf-like bracket to hang the thing lying flat on your belt. Sven sent me some files on it and among them was a nifty chest mount which will hook to the D rings at each corner of the Tek - I found it on Amazon and ordered one.
I had a Compass X-100 once upon a time and this reminds me of it. Powerful but weird - the tones are great however - no digital processing - the meter gives interesting little twitches on marginal discrim signals. Should be fun and good exercise.

Fisher Research originally released the 19 kHz Gold Bug model about 1987. It was a real breakthrough design at the time with a compact control box, S-rod, and elliptical coils. The detector is a good unit but is strictly all metal (no discrimination). It has no LCD readout and looks much like the current 71 kHz Gold Bug 2 but has a white lower rod and a black control panel face. Some people are confusing this old model with the new so be aware of this when looking at used detectors. The 19 kHz coils for the old Gold Bug will not work on newer versions of the Gold Bug below. The 71 kHz Gold Bug 2 is a totally different detector than the various 19 kHz models described below.
Around 2010 a number of new Gold Bug models were released by Fisher. First came the Gold Bug in 2009. Then came the Gold Bug SE (Special Edition) which added manual ground balance at a bargain introductory price. The SE with minor tweaks later became the Gold Bug Pro at a higher price. So now we have two basic versions, the Gold Bug and the Gold Bug Pro. They differ from the old 1987 model by having an LCD readout. The standard version of either detector comes with a 5" round coil. There is a Gold Bug DP (Deep Penetrating) which is nothing more than a Gold Bug Pro with an 11" x 7" DD elliptical coil instead of a 5" round DD coil.
The only difference listed by Fisher between the Gold Bug and the Gold Bug Pro is that the Gold Bug Pro has a manual adjustment option for the ground balance and also offers "higher sensitivity".
Both models use a "Ground Grab" button as a simple ground balance method that is quite effective. The Gold Bug Pro allows you to also manually adjust the ground balance setting up or down. The manual adjustment can be used in conjunction with or separately from the Ground Grab button.
The big question is the "higher sensitivity" claim. There are two possibilities here. First, that the Gold Bug Pro actually allows for higher gain or sensitivity levels. However, I was in marketing too long and have a more jaded thought. Manual ground balance allows for a higher degree of control that if used properly can get you more sensitivity. There is a very distinct possibility the higher sensitivity claim follows directly from the ability to manually ground balance the Gold Bug Pro. This could be tested with both units set side by side with identical ground balance settings and max gain. If the Gold Bug Pro is inherently more sensitive an air test should show it. I have not had the chance to do this my self but if somebody wants to there you go.

My opinion? I believe the Gold Bug and the Gold Bug Pro if outfitted with the same coil are basically the same detector. The only real difference is the manual ground balance option on the Gold Bug Pro. Do you need it? Not really, and especially when you consider that for $499 vs $649 that is probably all you are getting. The Ground Grab function is remarkably effective and would suit most people just fine.
I personally do like manual ground balance and so for me spending the extra money to get it is a non-issue. I do as a rule tell people that if cost is not an issue get the Gold Bug Pro. It is far more popular and would be easier to resell. But in all honesty I think the Basic Gold Bug is the real bang-for-the-buck unit. There is nothing else close to it at the $499 price point that offers full LCD readout target discrimination while in full power all metal prospect mode.
I should note that First Texas owns both Fisher and Teknetics. The Fisher Gold Bug DP (Gold Bug Pro with 11" coil) is marketed by Teknetics as the G2. The Fisher Gold Bug DP goes for $699 and the Teknetics G2 is $749. The $50 extra gets you a pistol grip rod instead of the Gold Bug S-rod and an arm strap. Nice gray paint scheme also. Really boils down to pistol grip vs S-rod, purely a personal preference thing.
I use the 5" x 10" elliptical myself and consider it to be the best all around coil for the Gold Bug. However, right now you have to get it as an accessory or as part of a two coil package. Fisher would be doing us a service to release the Gold Bug with this coil as standard on the unit.
My Gold Bug 2 is slightly better on the tiniest of gold but the Gold Bug Pro easily outperforms the Gold Bug 2 on larger nuggets at depth. For all around nugget detecting the Gold Bug or Gold Bug Pro (and G2) have a better balance of both small gold and large gold capability than the Gold Bug 2.
Fisher Gold Bug Pro & Teknetics G2 Detailed Comparison
To recap first came the original 1987 era Gold Bug with knobs and switches:
1987 era analog Fisher Gold Bug
Then in 2009 we got the new Gold Bug:
Fisher digital Gold Bug
Followed quickly and briefly by the Gold Bug SE. Note how the plus and minus buttons now have dual functions, both Disc and Ground Balance, compared to the basic Gold Bug above:
Fisher Gold Bug SE
The Gold Bug SE was basically the prototype for the Gold Bug Pro, which got a new faceplate decal and a higher price:
Fisher Gold Bug Pro
And finally, the Gold Bug Pro was also marketed under the Teknetics line as the G2 with a different rod/handle assembly:

I have never used the T2 Teknetics before. I have owned the original green T2 several years ago and other than turning it on and testing it out a little my buddy pretty much begged me to sell it to him and that was that.
So I have one coming to me now which is the T2 SE.
Now I have had the F75 SE LTD and from what I gather the difference between the T2 and F75 are this
F75 has a back light, the ability to save your settings and the iron disc stops at 20 and the T2 iron disc stops at 40. Plus the layout if the screen is different but similar still.
I think that is the difference between the 2.
Anyways, I am looking forward to getting it. I liked how the F75 balanced and it was a good machine.
So anyone else still swinging one of these??

Getting ready to buy another Omega 8500. I love the feature set on this detector.
I field tested prototypes of it and got a 1st production run model for compensation of my time, which I sold last year to fund some other detector purchases. Looking at the market there really isn't anything to compete with its feature set when you need something more than simple phase shift target id in its price range....when you get the chance take look at the operating manual.
I especially like the Multiple Target Category System:
This feature is available only in Discrimination Mode. For each target, the Omega 8500 calculates four independent numerical Target-ID’s on each pass of the coil; one primary and three secondary. Each one of the Target-ID’s will correlate to a target category on the LCD. There will be one solid primary category lighting up and up to three additional secondary target categories. All are different readings of the same target, with the primary category being the one with most reliable signal. If the Target-ID’s vary, they will show up as multiple illuminated categories, and this could indicate the detector is picking up noise, a faint/weak signal or that the target is irregularly shaped.
It has its warts but I have found some good gold jewelry with it, attaching a little 18K eye candy...
Now just to figure out where to buy it from.
