Hunting in all metal mode F75 LTD
- Thread starter pvtcook
- Start date
I dig anything above 12. I listen to how it sounds, as well. A scratchy or somewhat broken signal will be trash. Someting larger than a coin or bullet sized signal will probably be iron at low numbers. I hunt a lot in All Metal if trash isn't too bad. Any signal in all metal that's above what iron usually reads I dig. Even if the numbers a re bouncing all around. Deep stuff wont ID all that well, but will usually read either in the iron range or above.

Jimmy I'm just starting to use the all metal mode. Today I had some very good sounds but low vdi. I dug some of them and most of the time it was junk but at least once it was a bullet and I'm wondering if the deeper the target the vdi numbers run lower. I was running all metal threshold 0 sens 93. It's not trashy at all in the area I'm hunting. I would appreciate some input on this.

I am not saying this is THE way to do it but it is what I generally do. If the target locks solid at 15 or lower I pass. If It reads over 15 or if I can get it to "bounce" over 15 I dig it. Many small or very deep non-ferrous items will read ferrous in bad ground and so the numbers bounce around a lot. Anything other than a rock solid repeatable ferrous (15 or lower) I dig.
That said small non-ferrous items or large items at fringe depths can read solid ferrous and may get missed. The only way to get them is pretty much dig it all. The worse the ground, the more likely you are to get false ferrous indications.
If the goal is to get all non-ferrous targets and you are not digging at least some ferrous stuff then the discrimination employed is probably too aggressive. Again, that is just me. Some people hate digging trash. I have an extremely high tolerance for it. The only detecting I do not enjoy is when nothing beeps.

I can honestly say the F75 has found me more goodies in 6 months than all other years combined with other detectors.
I generally hunt this way. If I find an area that should hold some good stuff, I'll set the machine to de mode with discrimination set somewhere between 5-6. Then I'll dig all repeatable non-ferous sounds trying to clean the place up a bit. Then I'll switch over to the all metal mode, with the threshold set very low and dig all repeatable sounds. I've found many deep goodies this way. Running in the disc mode first really cleans up the area allowing the all metal mode to be more efficient.

The all metal mode is the ONLY way I hunt. A good "solid" repeatable target over 20 --- I dig it ! If i get a very very strong / large iron signal below 20, i raise my coil about 12" above the ground and swing it slowly If it beeps, i'm gonna dig it cause it maybe a cannonball, shell fragment, schenkle etc. Good luck.

That's pretty high sens, but if it's stable that's fine. Someone mentioned hunting in DE mode. I use DP Boost. It gives a significantly better/louder response. Some people feel it has a slower responce, but I think it's close. If in not too trashy ground, it's the way to go. Pay attention to your signals. After digging a lot, you will start to hear what a bullet sounds like in all metal. More rounded and a little mellower. Takes a lot of practice and I still get fooled on short stubby hails, larger nuts off a bolt, washers and iron rings. Can;t be helped. It's a matter of training your ear. That really helps on really deep targets that only give a slight TDI response. If it sounds right I dig it.
Hope that helps. It's like the tourist visiting New York who stopped a local and asked how to get to Carnegie Hall. The local said "Practice, man. Practice."
