705 - AM vs Custom program run wide open.( nothing notched out).

[Digdoggy]

Hey all, 705 with digger coil may be going on a morning hunt at a path around an old fishing spot in woods. Old air survey pic shows a couple side paths from long gone farm to the lake. Seeking old coins. What do you all think about running in All Metal mode vs my custom program, preset number 4 with everything notched back in or "Wide Open".
I've allways used that, program 4 wide open to hunt. I have not hunted yet in all metal. What do you all like and why. Say your in the senario above, seeking coins on old trail near lake in woods. Ground phase usually runs about 20 in that area.
Settings:
Digger coil 6" dd 3 khz.
Coin and treasure mode
Sensitivity - 20, 22
Tones- Multi
Auto noise cancel
Threshold just audible in phones
VID Stabilizer on
Auto Ground bal check then gb tracking on

Go to page 40 of Randy's book for the best description of why AM has it's advantages.

In a nutshell, hunting in a pattern of any sort the machine tries to fit each object into a specified target bin, which can cause the return signal to be clipped, which in turn causes a loss of some of the tonal nuances that I listen for.

I've always hunted in a pattern with nothing notched out and I'm able to discern those junky targets around 90-95% of the time. However, I do get the odd coin that can sound just a little junky. I must give the all metal mode a better try in the future, as to be honest, I've never really used it.

On the other hand, hunting in a pattern with nothing notched out can be advantageous, as it may provide a slightly better TID if the target falls very close to the border between two TID bins. This is especially so when your targets are high TIDs when running a HF coil and low TIDs when running a LF coil, as the bins are narrower in those regions.

Cheers, Ben

Sounds good (no pun)
but my choice would be as above but 2 tone.

I agree with OLH. I prefer All Metal mode. I use All Metal until I run into a spot where there are too many signals for my brain to deal with. Then I switch to one of the patterns for a while, and then return to All Metal as soon as possible. A few years ago I learned the great benefits of All Metal mode when I'm in the woods or in crop fields where targets are more or less spread far apart enough.

Use in AM and check it with your custom set or even more settings. Repeat. Consider changing to the 5x10 HF if it's rocky or highly mineralized OR if you have a lot of time to experiment. It's easy to change settings & coils.

On any detector I use disc mode when targets are close together, when I get two or more signals per sweep. When targets are farther apart I use All Metal mode, it gives a better, more accurate signal.
