Who has tried less than 5 discrimination

Who has tried less than 5 discrimination on the F75 for deep targets? Better yet anyone ever got a good deep target with <5 disc that disappeared when the discrimination was set to 5 or above?
 
I relic hunt with disc at 0 all the time, unless in real iron laden areas. Then I use 6 and mono tone. If not too trashy, I go all metal for max depth.

keep on diggin'

and yes to your question..Check the dirt You will most likely find like I did it's something that was iron and it rusted to nothing but dust.When you dug it..it broke completely up so you didn't find a target..........When compressed the detector could still read it as a target.
 
I've played a lot with DISC settings for deep turf coins and found no depth loss when increasing the DISC from 0 to 6. Of course, there is probably a slight depth loss when you do this, but for coins in the 7 to 9 inch range, there was not an effect other than the deep coins sounded 'cleaner', but slightly lower in volume. Overall, the advantages of running DISC above 0 (much less chatter) outweigh the slight depth disadvantages that may occur with DISC greater than 0. I find an appreciable increase in chatter when lowering the DISC from 6 to 4 at a turf park with relatively low iron content. DISC = 6 seems to be a magical chatter reduction threshold for my area. - Jim
 
I've tried hunting with disc 0, but it's typically pretty noisy, and I find that by bumping it up to 6 it settles down.

Have found a great relief in 'chatter' by using Disc' at 6 here in the UK...combined with PF or DE process and sensitivity at around 75.
 
My buddy let me use his F75 on Saturday to help me decide on what new detector I might want to consider. I only had an hour the night before to do a little reading on it, so I was pretty unprepared. I had the disc set at 0 and 1, but after I got home I read that anything under 6 kicks it into high gain. I had some chatter at those numbers but nothing unbearable and it still did great in trashy areas.

After reading the manual and reading the tips here I can't wait to try it again. Now I'm looking everywhere for a deal on a good used one, but their pretty rare these days. I think it's a great machine and I envy all of you owners.

I all most never go above 6 mostly between 6 - 0 depending on the trash .EMI will keep me above 0 more than trash
If EMI is a problem a small coil or All Metal mode will help. HH Mike

Mike you may consider the F70, I've seen some smoking deals on them here recently. It's essentially an F75 with a few less features (no non-motion AM mode, no trigger). Shares all the same coils, and the settings are essentially the same (F75 JE mode = F70 SL mode). From all posted real world accounts both machines appear to be equal in depth.

Just a thought.

Thanks Brian!
I've been reading about those and they sure are more affordable. From what I've read it's a much more stable machine with the F75 coil on it, so adding that will be another cost factor I'll have to count on.

For day in, day out, coinshooting, I'm pretty partial to disc. 6 myself. I have, though, used a good bit of 0-4 disc. and I do feel under 6 disc. does have a touch more depth in my ground when ever I've compared the under 6 settings with 6. On a true 12" deep quarter with 4 disc. I would get a nice repeatable, high tone tic. With 6 disc. and the same 3h tones, all I could get was a ever so slight tic, one I would not normally dig. A 6 disc. setting will hit most fairly flat laying dimes in my ground to 9." Slanted and coins on edge are a whole other ballgame. HH jim tn
