Does anyone think it matters what mode you are in, if you run a single frequency and all metal?

yes ,I do.. I hunt a very old site that has over 200 years of ground up whatnot,nails,cast iron bits of stoves,car parts horse shoes, coal ash,pig iron,aluminum foil bits,etc..Ive found 5khz works best at hitting copper and brass while giving me a fighting chance against the above listed debris..I’ve tried every combination I can come up with but 5khz is most productive at this site... multi frequency at this site gives way too many good signals on iron which wastes a lot of time and effort.. 10 and15 kHz are just a little too frisky on the small aluminum bits... really all depends on how the site reacts to your settings... I haven’t found any use for the 4khz ..you would think 4 and 5khz would probably be similar but they certainly are not in my opinion...
I just reread your post..park1 or field 2 seems to work best in the above mentioned site..mostly park 1 avoids the iron and small bits of aluminum while still hitting on small flat buttons and coins which can also be a somewhat low tone item..

Good info, bootyhound, I will have to try 5khz on my War of 1812 tavern site, which sounds similar to your site but maybe not quite as much trash... plenty of small iron and nails though, and as you said, the multifreq can hit hard on that iron and make it sound great. I've been using mainly multi frequency on in Field 2 and have pounded and pounded with AT Pro and more recently the Nox 800 in multifreq. Field 2. I tried 40 kHz in Field 2 just for kicks the other day and hit a very small tombac flat button that I had not hit before with either my AT Pro or my Nox 800 in multi/Field 2.... came up really low with target ID mainly around 2 but sometimes bouncing to 8, so it may have been on edge. So I think that experimenting with single freqs, depending on site conditions, can pay off.

I don’t usually run single frequency. But, in a trashy spot I have had good luck running park 1 in multi. It’s weighted towards the lower frequencies and seems to perform well. I have used 4khz randomly checking signals that seem iffy or really deep. Have pulled a couple good buttons and Nickels that way. In the cleaner areas I typically run field 2 in multi. I have gone back over sites that I have hunted a lot and used 40khz on field 2. Found a ton of .22 bullets that I had previously missed. If I have unlimited access I tend to go over the same places in different modes just to clean up.

I think if you are in single frequency it dose not matter what mode your in ,you are just in single frequency mode.

There is no true “ all-metal” it’s disc mode with nothing notched out. As pulltaber mentions, Single frequency is single frequency no matter what program you are in (Ex. Park1, park2 Field1, Field2 )
What will make a difference are your other settings such as GB, recovery speed and sensitivity. Iron bias doesn’t apply here as it doesn’t work in single frequency (pg 52 of the manual)
To answer your question, when using single frequency, it is my belief it doesn’t matter. Pick your single frequency, pick your mode and go have fun finding treasure! Good luck!
