I am looking forward to seeing your results. I decided to try out the F-75 myself, it is supposed to arrive today.

Good Hunting!

Its impresive! only got to use it for 15min but perfect in a trashy wooded area. I think i found my oldest wheat penny 1910. 5 wheats and a few clad. Goind to really give it a work out tomarrow. Will post pics. I have about 30 hours on the machine now and it just now starting to make sence. Im still learning alot and this thing is smokein!
 

is this F75 easier to learn then the dfx...cause I sure as heck do not understand the dfx?
 

BB hard for me to say as i never have used or held a DFX. I will tell you that i was very over whelmed when i first got it. One swing and get 20 signals. One thing i did was make a test garden in my yard. Doing that helped me understand the machine better and allowed me to test diffrent setting and how they were diffrent. The 75 can be setup hotter than what an area can handle that's for sure. The DFX is probably the same way. I still have alot to learn o it and havent even touched the other modes and what it can do.
 

I don't have the F-75 yet, but I am familiar with the DFX and I can tell you that if you don't like the complexity of the DFX, you won't like the F-75 (I've checked out the online manual, Bill Ladd's video, etc. and you do need to read the manual and practice with the machine).
 

I've only briefly played with a DFX so I can't say, either. The F-75 runs pretty good with the factory defaults, and whenever I set a notch I "reboot" the next outing to make sure I've cleared everything. From there I can set all the modes/tones/sensitivity and discrimination in maybe 20 seconds to start off again. I'm pretty sure the DFX takes a lot longer than that to pass through every setting. Great feature of the F-75 is that the menu options are all on the display at once so you can run down through them and you only need open the ones you want to alter.

If you're getting 20 signals every sweep try lowering the sensitivity. There is also a "buggy" range of discrimination, between 6 and 19, where a higher gain circuit is enabled according to a couple of the reviewers. If your unit chitters and chatters move the discrimination to 5 or below for added depth or 20 & higher to screen out iron & nails, etc. Unfortunately, the default is 10 and that's smack dab in the middle of the "hot" range. I've been running mine at 0 and relying on the VDI to tell me what I'm sweeping over.

A small coil is on my wish list. Hopefully soon.

I run Disc 0 sens 99 most of the time, i like to hear whats in the ground.
 

Yee ha! Mine sounds like the paniced telegraph key operator on the Titanic after the iceberg at sens 99. It just percolates non stop at most sites. I don't think I've ever been able to stand it over 92 or so except at one site that I can max it (and even use the jewelry mode!), but that depends entirely on the EMI nearby.

Last week at my local park the ice cream truck was making the loop and at 200 yards away his canned music was clicking and buzzing in time with the clicks my detector was picking up. Either we were both getting slammed hard by a powerful EMI or he was causing it somehow. Weird stuff. I managed to lose most of it by running up to frequency choice 7.

I think you got that backwards, booster amp is turned off between 5 and 19 on de mode...

Test it out, turn your sensitivity up until it starts to chatter and then back off a few clicks at a discrimination setting of 7, then lower the sensitivity to 1 and you'll start to hear some chatter again...


Also at a sensitivity of 99 you may be overloading the machine in it's own noise... A few units I have tested started to feedback above 95.

The DFX is FAR more complicated than the F75, you can control pre-amp settings ac voltage, dc voltage, and on and on, the DFX is THE most complicated and adjustable mass produced unit on the market...

Yep. My bad. I just went out and checked that. If I set the sens just to where it settles down and then click up to 6 it starts to percolate. :icon_pale: Somebody needs to write a detailed manual for this wonderful mystery box!

I've been running at zero disc. and no notch (reset w/nothing though it still shows "1") and have been happy with that.
 

Humm I have found that if you use tone 3 and up and sense 87 and up together it starts Buzzing but not all the time..not sure why
and the main feature to remember with the F75 is running low disc will 6 below I'm finding will give a big WOW effect even at low sense
Starts to hit targets like a pingball Paddle..and IF possible Turn up the sense and the Targets get even Louder..woooohooo awesome machine with Both coils..Its Fast and furious with finding close targets.. :thumbsup:...james
