Relic and gold machines
Fisher F75 vs Teknetics G2+: Related Relic Machines, One Real Difference
Quick answer
Buy the Fisher F75 at $419.00 for a documented 0 to 99 LCD target ID display, double-filter discrimination and a magnetic mineralization readout. Buy the Teknetics G2+ at $299.00 for the same First Texas relic-hunting DNA in an 11 inch DD open elliptical coil, with V-Break tone customization, for about $120 less.

Best for: relic hunting where iron is heavy
Check price on AmazonFisher and Teknetics are sister brands under First Texas Products, and Fisher F75 and Teknetics G2+ are close enough in philosophy that this comparison is less "which is better" and more "which is more thoroughly documented for the extra money." $419.00 against $299.00 is roughly a $120 gap, and for it Fisher publishes a large LCD with a 0 to 99 numeric target ID, double-filter discrimination modes, a magnetic mineralization bar graph and readout, trigger-actuated FastGrab ground balance, and 40-plus hours of runtime on 4 AA batteries.
The G2+ listing publishes an 11 inch DD open elliptical searchcoil built for separating targets in clutter, Ground Grab computerized ground balancing, V-Break tone technology for custom audio breakpoints, and FeTone adjustable iron audio, at just over 2 pounds. Both machines are aimed at the same job: coin and relic hunting in iron-heavy ground where target separation matters more than raw depth. The F75 target ID chart and G2+ target ID chart are the next stop for either one.
Top pick
Teknetics G2+
The same First Texas relic-hunting engineering as the F75, with an 11 inch DD coil, V-Break tone customization and adjustable iron audio, for about $120 less.

Why do these two machines look so similar?
Because they share an engineering lineage. First Texas Products makes both the Fisher and Teknetics lines, and the F75 and G2+ target the same customer: someone hunting old, iron-contaminated ground who needs to separate a good signal from a nail eight inches away. Where they diverge is presentation and a few discrimination tools. Fisher leans on a numeric LCD readout and a visible mineralization graph; Teknetics leans on named technologies, V-Break and FeTone, that do a similar discrimination job through a different control scheme.
How do the published specifications compare?
Both listings are reasonably complete, which makes the price gap easier to evaluate directly.
The F75 publishes a numeric LCD target ID and a mineralization readout the G2+ listing does not name directly, while the G2+ publishes an exact coil size and shape the F75 listing does not state.
| Model | Price | Stock coil | Coil type |
|---|---|---|---|
| Fisher F75 | $419.00 | - | - |
| Teknetics G2+ | $299.00 | 11 in | DD |
Figures are taken from each manufacturer's own published listing and specification sheet. A dash means the maker does not publish that figure for that model, not that the feature is absent.
Where does each listing add something the other skips?
Fisher documents display and battery life details the Teknetics listing does not carry, and Teknetics documents an exact coil size and shape the Fisher listing does not state.

Drawn from the Fisher F75 and Teknetics G2+ listings in our catalog. Each brand documents different discrimination tools in different language, which is why several rows read as gaps rather than true absences.
Choose the F75 if
You want a numeric target ID on an LCD you can read at a glance, plus a visible mineralization graph so you know when the ground itself is the reason a signal sounds off. Long battery life on plain 4 AA batteries also matters if you hunt far from a charger for days at a time. The full F75 review and F75 target ID chart are the next two pages, and the discrimination explained guide covers how double-filter discrimination fits into the bigger picture.
Choose the G2+ if
You want the same relic-hunting capability for about $120 less, and you are comfortable learning V-Break and FeTone rather than reading a mineralization graph. The lighter build, just over 2 pounds against an unpublished F75 figure, also matters on a long day swinging over rough ground. The G2+ target ID chart is the best published starting point until a full review exists, and AT Gold vs Gold Monster 1000 is the next comparison if mineralized ground is pushing you toward a higher-frequency machine instead.
What relic hunting actually needs beyond the detector
A proper digging tool matters more here than on an open park lawn, since relic sites mean plugs through sod and root mat. Lesche Digging Tool and Sod Cutter with sheath is the standard recommendation, and Garrett Pro-Pointer AT earns its keep fastest on exactly this kind of trashy, iron-heavy ground, where a five minute hand-sift becomes a ten second confirm. The discrimination explained guide and the test garden guide are worth reading before your first outing with either machine, and both pay off faster on this kind of ground than on a clean, low-trash park lawn.

Frequently asked questions
Are the F75 and G2+ really made by the same company?
Fisher and Teknetics are both First Texas Products brands, and the F75 and G2+ share a similar engineering approach aimed at relic hunting in iron-contaminated ground. They are not identical machines under different badges, each has its own control layout and discrimination tools, but their design goals and target customer overlap closely.
Does the G2+ have a numeric target ID like the F75?
Not published in this listing. The Teknetics G2+ listing in our catalog describes V-Break tone breakpoints and FeTone adjustable iron audio rather than a stated numeric scale, while Fisher explicitly publishes a 0 to 99 LCD readout for the F75. Check the current G2+ manual for its display specifics before assuming it lacks numeric feedback entirely.
Which is better for gold prospecting, not just relics?
Neither listing publishes a prospecting-specific frequency the way Garrett AT Gold or Minelab Gold Monster 1000 do. Both the F75 and G2+ are marketed primarily around relic and coin hunting in mineralized soil, and while their ground balancing tools help in mineralized ground generally, a dedicated high-frequency gold machine is the better documented choice for small nugget hunting specifically.
Is the price difference worth it for a beginner to relic hunting?
Probably not. A beginner benefits more from time spent learning one machine's discrimination behavior on a known test garden than from the extra display and battery documentation the F75 offers. The G2+'s lower price and comparable core capability make it the more sensible first purchase, with the savings better spent on a digging tool and a pinpointer.
Researched, not professional advice. This page is compiled from published specifications, manuals and owner-review consensus, not hands-on testing. Target ID numbers, depth figures and settings vary with soil chemistry, moisture, target size, depth, orientation and firmware version, so treat every figure here as a starting point and verify it against your own machine's manual and your own ground.
