Will an F70 or F75 beat a CZ-3D in depth and identification at depth?

[Tony N (Michigan)]

I've been looking at both the F75 and F70 and CZ-3d detectors.
Some say the 3D is the deepest detector out there and can rightly identify a coin down to 9 inches. I've never had a CZ-3D so I don't
know if that is a true statement.
Does anyone know who has used the F70 or F75 AND the CZ 3-D?
Thanks for any help.
Tony

I own an F75ltd, Tom tuned CZ 6a and CZ 5. In my soil the CZs will identify a coin better at depth than the F75. Now that being said I'm not saying the F75 isn't just as deep or deeper it's just different. To put it into perspective, I was using my CZ 6a in an old park here hunting old nickels with the 8in coil I got a hit that buried the depth needle. It was a consistent high tone, very feint in all directions wi th the need reading coin. I marked it with my pinpointer, went back to the truck, got my CTX and F75 to see what they said on the target. The CTX gave a 13 48 one way and a 12 49 the other wit h a reading of 10in. The F75 bounced it's ID on it from 45 to 93 with a depth reading of 13in. So as you see the F75 saw it, just would a person dig it is the question. If I was strictly a coin hunter in old parks in more modern trash I would choose the CZ over the F75. If I was going to hunt old parks, homesteads, places with lots of discarded iron trash I would opt for the F75.

Thanks Welgund for the good information.
Is the CZ 3D an earlier model of the CZ 6a and CZ5?

I am not sure but I am thinking I bought a new CZ5 long before I heard about a CZ 3D.

This order chronologicallyI believe

CZ-6
CZ-5
CZ7
CZ-70
CZ3D

Welgund, very well said. The 3d will consitantly Id an eight inch coin perfectly with both tone and ID. I will say that the F75 will probably go deeper, but past 6 or 7 inches, the tones and ID start bouncing. CZ's also do a great job identifying modern trash, but are not so great when any trash becomes heavy. Also, the Cz3d is limited to concentric coils only. The big 10.5 coil is way too heavy for me, but the stock 8 inch will go as deep as any detector I have used. I have wished for years that Fisher would come out with a modern, light weight dual frequency detector with both DD's anc concentric coils. A detector like this would "wake up" the industry!

The cz3d may identify a deep coin better than them both, due to no vdi. The gauge im assuming will hover over the say ...quarter range. The f75/f70 will jump back and forth like almost all machines when past 8 inches or so.

All of this is realitive though. If you live in Kansas with wonderful soil most machines will go deep. In my Tennessee clay/chert most machines struggle past 8 due to higher mineralization. I own an f70. It's light and super fast. Has a learning curve like most but it's a great machine AND you can get them and the teknetics patriot (f70 clone) for dirt cheap!

Thanks, Gannon.
I know REVIER loves the F70.
I live in Michigan where the soil has iron in it but there are areas in Michigan where the soil is pretty mild.
Some areas here a wheatback may go down to 8 to 10 inches. Just the other day I was detecting with a friend
and he dug a clad quarter at 10 inches!
One problem I see with the CZ3d is lack of coil selection.
I wonder if the CZ3d will lock on, say a wheatback, in my soil at 10 inches?

Would you say the F70/F75 would do better in iron trash due to having a DD coil? But the CZ in more modern trash, i.e., pulltabs rusty bottlecaps would be better than the F70/F75?

 

[Welgund]

If it's heavy iron trash like cut square nails, flat tin and such then the faster recovery speed of the F75/F70 would be my choice with the 3 x 6 elliptical concentric, or Nel snake coil. Now if I'm going to go to an old trashy park, modern and some iron j would take the CZ with 8in and 5in coils and old nickel hunt cause the CZs are the kings of old nickels.

I have both and use the 3d more often now. in my soil the f75s vdi jumps around so much I don't even really pay attention to it. in my test garden the cz is deeper by a couple of inches and the depth meter is dead on. just wish the 3d was lighter. ive found more nickels and indian heads with the cz than I have with all my other machines combined.

That's cool to know.
How deep is the deepest coin in your test garden that the 3d will hit on and accurately identify?
What kind of soil do you have?

 

[juit]

Unless f75 pulls dimes at 13 inches

 

[Cameraniac]

Unless f75 pulls dimes at 13 inches

If it does, it had better tell me so that I can leave it for the guy with the CZ-3D.

A couple of years ago at our club's end of the year seeded hunt festivities in great Kansas soil a member planted a coin test garden just so the members could test their rigs for depth for fun.
He buried copper cents at 2" depth increments from 4" up to 12".
Newly planted test gardens aren't always exactly like conditions we come across in the wild but it was an even playing field for everybody that tried it.
My Compadre could hit the 6" coin but not the 8" one but then I pulled out the F70 without headphones.
I was in disc and multi tones and nowhere near maxed out sense and thresh and hit every one solid all the way up the line.
A little jumpy on the numbers but they were all high...a for sure dig me signal if I came across this in the field.
As I was swinging over the 12" target getting a solid tone on every pass back and forth the guy who planted this test garden was in the vicinity and came over after he heard those solid tones.
He used an AT Pro and he said he watched a whole lot of people test all kinds of detectors on this thing all day and not one that he noticed hit that 12" coin anywhere near as well, consistently and as solidly as mine did.
A few weeks later he bought a new, top line F75.

I wish he had gone a little further and buried 14 and 16" targets too...I bet I could have hit the 14" one also and maybe even the 16" but I will never know for sure.
