I'm attaching the manual (downloaded from Fisher's site). (Edit: see Steve's link in his response below.) On page 9, bullet point 4. it says: Still holding the GEMINI-3 parallel to the ground, slowly turn the balance knob (with arrow) on the three-piece handle counterclockwise until you get silence (null) and zero meter reading.
My question is this: is the knob actually doing an electronic adjustment (such as being attached to a variable resistor or capacitor) or is it just re-aligning / repositioning the transmitter/receiver/attachment rod to optimal location?
Detected a stretch of a river that had some erosion on the banks and sand removed down to the gravels. I dug up many coins including a buffalo nickel and a silver dime that someone was going to make into a ring. The best find was a 14k ladies ring 3.1g (not a genuine stone). Also dug up what looked like a white gold ring turned out to be stainless steel.
The tarsacci has good recovery speed like the T2 worked great in the trashy area with broken pieces of rusted old steel cans, bottles caps, bits and pieces of iron along with all the newer junk tossed into the river. The tarsacci worked better than my T2 it found targets in a area I couldn’t use the T2.
The 2 wheat pennies were dug up at a old park 6-7 inches deep. The tarsacci goes deeper it’s just that my ctx did a good job sniffing out most of the oldies at this old park.
I found this site while doing a search for detection depth in dry sand any way it is a good read but they have some really Wild looking detectors with some crazy frequencies listed in the chart link also check out there machines under the heading at the top left,
I would like to hear what you Guys think of the first link.
Please note that in this first link there is a link to the Boot of Cortez which is worth a read.
I think the F11-F44 was their futile attempt to go after the all terrain market that Garrett, and now Nokta Makro and Minelab have all entered and dominated. I have a feeling that, aside from the new coils, the F11-F44 wasn't so much of a new design as it was incorporating existing off the shelf designs from existing detectors to make a weatherproof detector. IMO they missed the mark, and I don't think these machines ever really took off. To be honest there just wasn't anything that stood out about this line. If you're the last one to enter a crowded market, you need to make something that stands out as different from your competition be it a far more competitive price, better features, or better performance, and I don't believe this line adhered to any of those factors.
