Curious About Fisher Cz Series Detectors

[Badger-NH]

As long as I've been on this forum, I never knew that Geotech was Carl.  😀

My Cz6 and 6A loaded me up on gold on the salt water beach. It would make a "Ping" sound on deep silver on turf. Nice.

Badger, did you ever see....whats his name....Old California....i forget his name....anyway, he put the CZ box under the arm but put the faceplate in a box on top so you could still see the meter and use the pinpoint button.   Made a nice looking easy swing unit......Paul...Paul (CA) is his name.    He did some really good mods on the CZ.  

To me...the F75 LTD was a good replacement for the CZ series.

Sorry, for the late reply. That sounds familiar. I've seen some pretty cool mods over the years. When I talk about the CZ series, it mostly has to do with beach detecting because that is where Multi-frequency really shines. I would choose an F-75 over a CZ any day for land.

.. The CZ design is best thought of as a single-frequency (5kHz) detector with the ability to cancel salt. The 15kHz component is weak and not all that useful for detecting targets. I once proposed a variable frequency design that works the same way but the user can vary the primary frequency from a low of 2-3kHz up to the gold range, maybe 50kHz. At lower frequencies the user could turn on salt cancel. The idea got no interest.

Going a little off topic , I dont know the CZ neither the F75 but I know the T2  . I have used the T2 on ultra iron trashed areas in France a few years ago and I have been very impressed with it and its sharp and "crystal" audio .. Very impressed by the FA mode btw , its a magical mode , absolutely silent on nail beds with incredible reactivity on targets  ..

I did not keep it because it is a little too heavy for me ( 1,57kg ) . I think that FT could release a new redesigned T2 version , modern and lighter ( 1,1 or 1,2kg )  with a lithium/ion battery , a slim digital screen, a carbon shaft etc  . No need for multifrequency , keep 14khz as it is very polyvalent and works very well, keep the same electronics just reduce the PCB size , like on a Garrett Apex for example . Keep the 28cmX18 coil size as it is a very good coil too ..

I think that such a detector would be appreciated by the users ...

My gosh ... I must be used to the waterproof beach detectors ... when I picked up the F75 (same weight as T2) yesterday to check an area of the yard at our new home before putting in a raised bed garden I remarked about how light it is.

Yes but the D2 I am currently using weighs around 800g , half the T2 ...

F75 / T2 control boxes are lightweight, smaller electronics PCB's etc are not the way forwards.
A lighter shaft would be viable. The lower moulded carbon/resin shaft could be replaced with a woven rod ( like the ML Equinox for example ). The middle section could be thinner gauge tubing ( like the Eqx; 0.040" versus 0.056" ). The upper isn't suitable for thinner tubing, due to dodgy design.
The T2 battery is situated where it's doing useful counter-balance work. If it's replaced with a Li cell, it needs to be a similar weight ( 100 grams ) , eg. 3 x 18650 or 2 x 21700. This would give huge run-times, likely 100+ hours, which would be a unique selling point , but not really that useful to most people.
( Sorry for the off-topic )

I owned a couple of the beepers in the Cz family and they were deep and sure made my nickel count go up-they loved silver and nickels-IMO Very solid beepers for coins
