Got my F75 last Wednesday and have about 18 hours on it.
I started in the De mode, sens at 50 and disc at 20. My ground read about 70 after i ground balanced with fast-grab.
Here is my first tip:
Make sure you don't see the words "can't GB" on the display while you try to GB with fast-grab. If that happens the detector won't have any performance.
On the first day the F75 was very erratic at sens 60 and i learned later that a thunderstorm nearby may have caused that problem. The next days i was able to run sensitivity much higher without any problems.
I found that the F75 with sensitivity at 30 (99 max) in DE mode was as deep as some other detectors at max sensitivity on my test dime.
After playing with the F75 my favorite settings are:
De mode, tones 3H, sensitivity up to 95, disc at 5. It seems when you set disc from 4 to 5 that the internal noise is gone. Lower than 5 make it a little "chatter". The "always on" back-light is very great and it doesn't seem to use much battery power because the battery meter still shows full.
The JE mode is very hot and i found it to be as deep with a setting of 35 as the DE mode on 60. If you find a location where you can run the JE mode with high sensitivity you will have extreme depth.
If you just started with the F75 be careful with the JE mode since you can overpower it easily.
I have used the F75 mostly in DE mode and it does very well. I pulled some coins and a token from depth of 8 inches with a clear "bang" from the audio.
The best is the speed of the F75. The recovery and target response speed is the best i have ever seen on a detector. In combination with the DD coil it opens up new possibilities. I tried to over-swing the F75, but it is impossible. The VDI numbers and tones show up so fast that this has to be the fastest processor in a detector at this time.
The good thin is the faster you swing it, the better it Id's and the deeper it detects. You will get some ground "chatter" with the F75 but in a short time you'll know the sound of a good target hit.
The "depth on the fly" is a feature that i already liked on the Ace 250 and the discovery 3300. It is very helpful in conjunction with the VDI numbers because the numbers drop with depth.
The user interface is very easy to use after you read the manual once.
The all-metal modes (static and motion) are the deepest i have seen.
At sensitivity at 60 (99 max.)in motion all metal the detector had no problems with a nickel at 15" (air).
I use killer bees or rat-phones with the F75 (work great).
Summary:
I like:
1. The weight and balance
2. That it uses only 4 AA batteries. (Buy a smart charger with NIMH rechargeables)
3. Grip and armrest (you can bent the armrest to fit your arm.)
4. Extreme processor speed.
5. Audio that "bangs" on targets
6. Different tone and independent signal processing modes.
7. Depth
8. Large VDI numbers
9. Fast-grab GB
10. Notch system
11. Target separation of the DD coil
What i don't like:
A little chattery, but i thing that is the trade off for the power and speed.
No small coil right now. (i hope that is going to change soon)
The detector seems to to like thunderstorms and power lines.
What the next Fisher should have:
The F75 performance will depend on the mode used in conjunction with the sensitivity settings. (Je mode has higher gain than DE mode)
How about a gain control on the next fisher ? And maybe automatic ground tracking AND manual/fast-grab ?
OK, that's it for now...more to come.
