Question about F75 visual ID

[Tymstamon]

Howdy folks, I have been watching a bunch of you tube videos about the F75 and i just want to know if the numeric id jumps as much as it is shown in most of the videos. The tone id seems very solid. If the numeric id bounces so badly why.didn't they make the target windows larger but keep the tone id the same. Also how does it compare in the depth department to the CZ models. I've been considering an F75 for more than a year just don't know if it is enough of an improvement over my CZ-3D

Most of the time the jumping VDI readings is other targets next to, or close to the original target. The machine is that fast on recovery.

I sold a Tesoro, cz6 and cz3d after getting my F 75, I liked the 75 that much. I am digging deeper coins with the F 75 then I did with the cz's, but that may be just me. The cz's are deep as well. Because the F 75 is so sensitive, it does tend to id a little bouncy as it is reading everything under the coil. Although I go by tone first, if there is nothing else under the coil but a good target, it will lock on and id said target at 7" deep, or more. The key thing for me, though, about the F 75 is its capability to sound off and id good targets from among other trash targets. Hence, the most usual cause of a bouncy id. HH jim tn

The visual ID routinely bounces around on deep targets. Ignore the readout and listen to the tones. If it is deep and has the tone you are looking for (high vs low conductor preferences), dig it. F75 can get fooled on deep pulltabs, gives a high tone sometimes. But, if you rotate the coil around the target and the tone falls into mid-conductor range, walk away, it's a low to mid conductor.

The VID on all detectors are like your eyes from far away it could be a hot!!! target

When you get close you will find out, oof

The visual ID ing is i would say only a guide to tell as near as dammit what the Target ID is likely to be . It `might` jump about a bit or it can "lock on" .
The SOUND the target makes in my humble opinion is whether you decide to dig or not . If when your F75 detects a good target and is worth digging ,you know by the Sound whether its worth digging or not. Couple that with the ID second ,and you have your answer.
I don`t think i`ve ever had a Target Digital ID on the screen that is too far apart in the Variation of numbers to baffle me.
So to give an example , If your target is Visually ID `ing with numbers such as 35- 45 . Thats a good enough difference to Still warrant digging and it being a good target still. I don`t think there`s ever been a time when there is a massif wide difference on the reading that i`ve ever seen. So , you will never see a reading jumping from say 15 to 45 that i can ever remember seeing . The only time i could envisage something of this type of thing happening maybe is, if you had say a artifact of non ferrous with a small bit of ferrous attached to it then you would see a dominant Ferrous reading with a flicker of non ferrous jumping into the screen reading here and there. Depends which of the two is more dominant that the other . If it were a lot of non ferrous numbers with the odd ferrous creeping in ,i would still dig .

has mid-tone components to them, though the dominant tone was high. These turned out to be silver coins with pulltabs next to or near them. This happened with a 9 inch deep silver quarter that had a pulltab 2 inches above it. No problem hearing the quarter.

Thanks for the info guys, If the visual target id jumps that much i don't know why fisher didn't make the numbers wider in numeric value in specific conductivity ranges, for instance if a CZ model had a numeric id that was as tight as the F75 it would be all over the place also.Even slight differences in corrosion would make it bounce, but they made the target window large enough to to include a number of conductive targets. one F75 video was very interesting to me and it was this fellow in California detecting an old park/carnival ground and some of his signals were on very shallow wheat pennies jumping every where,now he did say it was heavily mineralized. Does this mean even shallow targets have a hard time locking or was it bad ground. I,like most of you hunt by tone and that is what makes my final decision to dig so maybe it is the detector for me. Once again thanks for the help HH. Tim

As others have said there can be a fair degree of fluctuation on the vdu.

My approach is to go round the target sweeping from every angle of the compass so to speak.

Whatever angle gives the best two way or even one way good sounding signal then i check the vdu, it's at this point
when it will be most accurate and i dig anything above 18.

It can still be fooled from time to time but i would rather dig a few none keepers than risk missing any.

Take care. Mart.
