... or at least I think it should.
As he stated, the Teknetics T2 was designed, from the ground up, to be all that it is. And just what is it? It is the best balances, most maneuverable, easiest adjustable, and most versatile detector I have used for most hunting needs. The ONLY thing I wish it had available as an after-market option would be a good round concentric coil of about 6"-7" in diameter. I am very partial to a concentric coil, for many reasons, and while the SDD coils for the T2 work, I'd still like to have just one smaller-than-stock round concentric coil.
Now, to the G2 and Gold Bug Pro or Gold Bug DP (a 'Pro' with a different stock coil). The Gold Bugs are just your basic type of 'S' rod configuration. they are light, hand-feeling, and you simply pick the model with the coil you feel you would use the most.
The G2 differs in that it uses the same hand-grip system and rod angles as the Teknetics Omega. I like the Omega and find it comfortable, and the grip is the same as that used on the T2. So, I like the Tek. G2 physical package ... but I seldom use the big 11" DD coil because it just doesn't 'fit' in most of the sites I prefer to hunt. Most are very brushy, have some building rubble at times, and most are rather trashy. Quite trashy might be the best term, and for those sites I prefer the round 5" DD coil. I leave the 5" DD mounted on my G2 full-time, keeping the 11" mounted on it's own rod just in case I need it for a more open, sparse-target site.
Some people are brand loyalists and just like the Fisher brand name so they go for the Gold Bug Pro or the 11" coil equipped Gold Bug DP. Personally, if I didn't have the G2 and I was looking for an excellent model detector with a flash-of-light speedy response and dazzling recovery rate, and knowing that the 5" coil was all I would likely need (or want) due to the types of sites I prefer to hunt, then I'd just look for a Gold Bug Pro and be fine with that.
I will add a comment here, too, about the great suggestion Dave J. made with regard to rod length and coil presentation because it can have a great bearing on a person's success rate ... as well as fatigue factor. I prefer smaller-than-stock coils because I hunt trashier and more challenging sites most of the time. I prefer smaller-than-stock coils because they balance well and are less fatiguing. I like smaller-than-stock coils because you can often sweep at a slower rate than with a larger coil and that lets the coil/detector work better in trashier sites, or when hunting around brush, rocks, or other obstacles.
I always suggest a person keep the rod length shorter so that the search coil is positioned about 12"-18" in front of the leading foot. and I also warn against making a too-broad sweep from side-to-side. I usually keep my sweeps at about 30" to maybe 36" from side-to-side, overlapping each sweep by
at least 50%. Fast sweeps often result in poor coil position with the ground near the ends of the sweep, and they also seem to encourage a faster walk-speed, and that results in less overlapping, too many missed spots in the path you think you've covered, and gives a false impression of just how efficiently you ,might have worked a site.
I hit the road a month ago yesterday, may 21st, and have traveled through 3 states and have called on a number of dealers/potential dealers, and hunted with many people I have encountered. This time has also included a 3-day outing with a group of 28 detectorists, and extended outing with a family of three to hunt a couple of good areas, and I have observed far too many people who need a little help and suggestion on sweep speed, coil presentation, coverage and overlapping. That's a project for out July 9th meeting, I guess.
Anyway, any of the GB Pro/GB DP or G2 models you consider will get the job done in most applications. I feel the main consideration, with the coils they are offered with, is first for you to determine just which coil YOU feel will be used the most, then pick the models that provides that coil.
Don't forget to let us know what your decision is, and how the detector/coil handle your needs.
