Final cleaning of the 1855 Half Dime..... and it grades a F-12..... maybe 13-points. Glad I dug this 'zinc penny' reading! The 1920 SLQ is what turned out to be better than expected..... and grades a VF-30. Date stands out much clearer after proper cleaning. Penny was a 1913 wheat.... in EF-40.

Rain/moisture will "activate" the iron...... especially the oxides of iron and cause erratic detector performance.
Also, a Disc setting of '6' is perfect for discriminating out almost all small iron (usually nails) in almost every case. You might be running into the 'exception' whereas you need a Disc setting of '7' to disc out your specific era nails in

Try some chewing gum foil and a soda tab off of a aluminum can.... and see if this gives you a mid-tone. The meter will always stay locked onto the last tone heard. If you pass over a penny and the coil is never passed over another object..... the needle will stay locked onto the "high coins" icon (the dime/quarter/half/dollar & copper penny icon). If you hear the slightest of au

Jim,
Your type of hunting in concert with your perspective is always fascinating. You are the only one (that I'm aware of) to use the F-75 in the capacity of nugget prospecting. I know the bulk of the crowd uses it in a more general fashion..... relics, coins, jewelry etc. ,,,,, yet, I'm certain the unit has merit in your capacity.
As far as the level of stability (zero EMI)

Hi Jim,
Welcome back. I can only surmise the F-75's processor speed is faster vs. the MXT's Sat speed. That's one area about the MXT I have not researched.....as of yet. (( I have a small pile of CZ-3D's on the bench requiring Calib for several folks )). Yes, the T-2/F-75 operating freq is much more resonant with lower conductors such as foil (and nickel) range. While th

I have not kept track of the mid-line units...as much as I have kept track of the top-end units. I can not answer this question. Maybe some of the other folks can.

The meter will ALWAYS move with the tones.... provided there are no 'meter' problems.
I'm still concerned that you have 'regular' newer nickels that ID as 'foil' ,,, 'nickel' ,,, and some ID as 'round tab'. The nickel 'span' on a CZ is hardly ever that wide. Silver nickels from WWII will do this.......... but certainly not the ne

Rodger,
Are you sure that your unit is ID'ing nickels as 'square' tab...... or are they 'round' tab? There's justification as to why I ask. Your meter/needle may be out of adjustment... (it requires alignment/calibration also). And are the nickels that you are using... newer nickels...... or are they Shield nickels/WWII silver nickels... or something unique a

Bill,
Most detectors do not function (if at all) on the salt mineral beaches. Electronic salt compensation is a 'must' for proper operation; however, this mode will detune the detector to smaller gold items (unfortunately). Salt compensation is a electronic phase shift angle adjustment. The CZ-20 & 21 compensate for salt very well...... but do not have a switch for regular dir

Yes, if you are 'fresh water only' hunting..... DO INDEED acquire a unit that is NOT locked in the 'salt' mode.... and/or gives you the option.

Yes, if you are "coins only" hunting in a highly trashy area....... by all means,,,, use the "coins tone" ...tone selection (that being 3 or 4-tone). If you start to find Barber dimes...... switch to 4-tones and start digging the top 2 tones...... as all of the Indian Head pennies will audibly ID as the second-highest tone (3rd tone).... whilst in 4-tone mode.

Dan,
I'm uncertain what you mean by 'Auto balance' mode. The best method to Grnd Bal is to place detector in Auto Tune mode (the next setting below '0' Disc).... and place Sens on '10'. You should hear a mild threshold hum in your headphones. Bob the coil whilst adjusting the Grnd Bal knob. Set it for neutral response. MAKE SURE YOU ARE NOT GRND BALANCING

If you are certain that your use for a UW detector will spend 80% ...or more... of it's life in/underwater, I'd recommend the 8" coil.
As far as detectors, my choices would be a ML Excal-II ...... or a 'depth-tested/verified' CZ-20 & CZ-21.
Tigershark not bad at all......... but Excal's & CZ's are on the top of the list.

As you can see, there is a "difference" on your detector as to how the 8" coil vs. the 5" coil; however, it sounds like your CZ-3D is calibrated to exact spec's with the 8" coil.
J.T. ...... Yes, the 5" coil is an ideal ticket for high trash areas, , , opening doors that would normally be closed. My recommendation (if possible) would be to try a few different

Yes, on the White's MXT.... the pinnacle iron Disc setting was between 1.8 to 1.9 (almost exactly 1.9).........and this was on 4 different MXT's. Stunning/impressive tight tolerances from detector-to-detector. Exceptionally impressive.... considering analog 'dials'.
MXT is VERY quiet in the iron. Commendable. Yet, , , problem is......... it's TOO quiet; .... ie 'm

The coil that came with the detector (from the Mfr) ..... which is usually the 8" coil....... is the most "ID" accurate (unit is usually calibrated to that specific coil also). Switching to the 10.5" coil and.....usually.... the CZ still retains extremely good ID accuracy. Now,,,,,, the 5" coils CAN induce the least amount of ID accuracy, regardless of 'Enhanced'

Bill & Tom,
Yes, all of the above applies to the F-70 also. Keep in mind..... the F-70 (overall) has nearly identical performance to the F-75... but MUST have the same coil as the F-75 (yes, can be interchanged). With the 9.75" elliptical coil on the F-70.... on average,,,, there is approx a 1.5" loss in depth capabilities on coin-sized targets. This can be circumvented by ins

Yes & No (not the answer you wanted to hear). The small coil will 'see between' trash items much better..... but, the 5" coil is most prone to impedence mismatch... causing improper ID..... especially on nickels. If you can 'try before you buy' ....... that's the best method.
