These iron nail hitting at 21-22 is driving me nuts and not even having a iron overload kills me. Uggggh frustration setting in with these falsing nails.
Try iron bias of 3 or 4 and see if that helps.
Problem with iron bias is that it can keep keepers masked is thick iron. Falsing nails typically will have a ferrous grunt associated with them if you switch to all metal and/or will only hit one way if you turn on them. Also the TID will typically change if you hit them with two different modes (e.g., if you are searching in Field 2, try Park 1 or Field 1 to see if the TID changes). I typically have the "opposite" search profie in the User Profile slot to make it easy to switch between a "1" and "2" mode. Audio quality is alsi a giveaway if you can pick up on it especially in 50 tones, it will sound "off" or distorted vs. the solid ping of a coin. HTH.
I get what you’re saying v it just seems like a lot of trouble when searching in places with a lot of iron pieces/nails etc. Seems like I had the opposite problem with my max and F75. I could tell it was iron, but good targets where also iffy at times where the 800 smacks good targets, but the iron falses can also sound good enough to risk a dig. I’ve just been losing bad.
Although by digging all those iron nails I did get that Bust half dime (plug had six nails in it), but the ratio is at 1000 to 1 at this point. Not good odds says my back and arms.
Or maybe the smaller coil will be my savor at this particular site.
OK. Here's the way I look at it, Truth. Iron Bias will get rid of the falsing to a degree. Though, I really haven't found it to be that effective, actually, especially when you consider the downside of missing masked non-ferrous. So the filter may quiet things down but you will also not hear (filter) that busted amongst the nails. I don't think hitting one button (all metal horseshoe or user profile) while pivoting 90 degrees is a lot of trouble to decide whether or not to dig vs. just digging the nail on the false. You will still dig nails even with these tricks, but they should be fewer and far between and you should have a better idea when you DO have a solid potential keeper target. If you have silver down there, I guarantee you will have a better chance of digging it by keeping the iron bias filter off or low than if you use iron bias. If the nails aren't that thick and masking is less likely, I would use go ahead and use iron bias if the falsing is unbearable. That is not how I roll, I like to hear it all and let my brain make the decision based on using these target interrogation techniques and audio queues. Bed of nails, however, and iron bias will filter out the goodies too because you are effectively lowering the recovery speed. If the goodies are not too deep and you have a bed of nails situation, backing off on the sensitivity (called sifting) is also a good technique. You can even apply some iron bias in your "opposite" user profile program (like using Park 1) to see if that knocks down the false when you switch from minimal bias to high iron bias to see if that knocks down the signal. Another dead giveaway that you are swinging over iron. Really, though, to master this sucker, it really comes down to learning what the audio is telling you. Not just pitch which corresponds to TID (hence the false) but audio quality and strength of the "ping", as I previously mentioned. There really are no shortcuts when it comes to thick iron. I agree the 6 inch coil will help because there will be less iron under the coil. Good luck whichever route you choose.
Mate iv'e been having the exact same issue , last Sundays search did my head in digging nails. I have no answer but i will be following post closely to learn , i was making adjustments on iron bias but was putting numbers higher..........to cut iron should the numbers be lower ?
One thing i did invest in is a strong magnet to go on the end of my shovel , that way i can clean the iron out fast and double check for a good target without chasing small bits of nail around the hole.
Vferrari is correct. However, consider this, I went to a site someone I know cherry picked and using factory setting did very behind them. There is no such thing as not digging some iron. The 6" may help, it probably will, but any small coil like that will highly limit the ground you can cover in a day. I had one for a different machine but gave it up for that reason.
If the problem prasist go to the F75. We had a conversation about the sniper coil. My 75 LTD does great in iron with the small coil. Sometimes you just have to adjust. I keep the sniper on the F75. It's good around old home sites when set up correctly. Not saying the 800 can't be fine tuned but you list the 75 in you profile. Why not try it. When you are digging iron all day you might sacrifice a little depth.
For the 30' area, you will have to go over it multiple times at different seasons of the year to really nail it. It took me 3 years to get MOST of the items out of a 10' x 20' area in VA in the horrid red dirt with my Deus. It has almost given up the ghost now since I got the HF coil for the Deus. That thing beats anything on the market. Really. Goes real deep too.
Technology may change again, however with that said, since I'm turning into an old toad, I probably won't get another machine...ever. But you never know. I have firmly decided to NOT go in the water, even the ocean water. A local lady was at the beach and caught some kind of neurological attacking organism that left her in a wheelchair. It's bad enough with the hypodermic needles at the beaches, let alone what you can't see in the water.
I had to bail on the equinox because it hurt my arm to use it, and if mess that arm up, my MD career it just plain flat over.
