fisher2,
I have asked the same question on this forum but have not gotten an answer. I had heard the same about losing depth when you add discrimination but it was always in regards to other, non FBS machines. I have experimented by finding a target in All Metal first, then switching to a discrim pattern for relics to see if the signal changes but have not seen any difference at all. So far, I have not had a single target that read in AM but was lost, or even gave a lesser signal, when switching to discrim.
Also, I was on a dig in Culpeper county VA, where the soil is so mineralized it is considered the worse conditions available for relic hunting. The general rule of thumb there is "dig every signal" and carry out the iron junk that you find. After an hour of seeing every iron target read as iron (but digging them anyway) and every good target read as lead or brass I switched back to my modified relic pattern and spent the day finding bullets and cuff buttons at about 8 inches... and didn't dig any more iron trash.
Since then I generally use the modified relic program and have had no problems finding deep targets.
Just a humble opinion,
TomH

Tinfoil,
Thanks for the info, your input is always appreciated.
Linwood,
No secret
I notch out from -10 to -7 and +40. I have never gotten a signal in the -10 to -7 range that was anything but a cut nail. I leave -6 to -1 active because larger iron like shell fragments or rusty guntools will fall into that range. On that dig I found an Enfield bullet puller that would attach to the end of the rammer and it read a solid -3. The only exception I have found is that rusted nails that have been curved by getting hit by a plow read a perfect bullet signal (32/33 with a nice flutey tone). Scrimming out the lower negatives has seriously cut down on the amount of small iron trash that I dig and have to carry out of the field.
Getting geared up for another Culpeper dig on the last weekend of October, three days, 10 to 11 hours a day. This time I will be armed with the 15" WOT Coil (and a Swingy Thingy to help my tired old shoulder) along with the stock coil and confidence is high. The Safari worked much better than expected in that horrible powdered iron they call dirt down there and with the larger coil I should be able to cover ground quicker and find more goodies.
ngrelic,
How's the hunting in good ole GA? The ground is softening up and the crops are geting harvested here in the Burg so I should be able to get out a bit more leading up to the big hunt. Got a couple of new places to try and I want to get back to a couple of old haunts now that I am more familiar with the Safari.

Tom,
That sounds like good discrimination info to me. Thanks!
The woods I hunt call for the 7&1/4" coil and the Safari shortened to where my arm is almost straight down. This makes for a longer hunt in the thick woods around here. Also use it shortened in fields with the 11" coil as this is easier on the arm. Can see where you need the Swingy -Thingy for that big coil because it would have to be held away from you and then it probably weights more also.
Good luck at Culpeper.
Regards,
Linwood

Linwood,
I use a 5x7 DD coil in the thick woods, but generally we are out in fields where the bigger coil is an asset. We still don't know where we are digging in October because the organizers keep it secret until the Thursday night pre-hunt meeting. They let us know the area available to us and supply us with maps and information about troops that are known to have spent time on the property. After the meeeting we go back to the hotel to lay out the Friday morning hunt based on what our resident Historian (Dean Thomas) decides is the best place to start. Then we let the relics determine where we go from there. Rumors have us working on one of two sites, one is more than 2500 acres and the other is just under 5000 acres, both with large open fields and lots of ground to cover, so I think the 5x7 may stay in the truck all weekend
Do you dig for relics or coins, or a combination of the two?
Later,
TomH

Tom,
Started out only relic hunting back in 1968 mainly because had no good discriminator and the woods was the place to hunt. Later started coin hunting and now mostly coin hunt. Still like civil war relics though. Went on a 3 day organized hunt in March on Lees retreat route from Petersburg and had a good time, saw some fellows using Minelabs and having good luck, one even found a gold dollar. I used a Fisher F70 on that hunt and it worked well. Still use it a lot but since I started with the Safari, it is probably a little deeper machine.
That 5X7 DD coil looks good! Thinking about investing in one and trying it out.
Thanks for all this good info!

I haven't taken the time to answer the original question because, though I had my suspicions, I have never really attempted to try and see if discrimination actually affected depth on the Safari.
So I decided to set up a custom program, leaving open only the values +12 to +14 and +32 to +39, and kept my sensitivity at its normal 11 setting. Normally I detect in all metal and only switch to relic or coin when I think some junk is interfering with a good signal.
Anyhow, I took the Safari to silver schoolyard #1 for a couple days (approximately 2.5 hours total). This is an all grass school yard and deep targets (9-10") are not uncommon. The average hole with my custom program was between 4-5" and my deepest was a penny at 7". When I detect in all metal, it is not unusual to be digging 8" holes consistently. So methinks that perhaps discrimination might affect depth to some degree, but then again I've only tested the program for two and a half hours so my testing is far from conclusive.

A couple days ago I took the Safari out again with my custom disc settings, and managed a 1919 wheat penny at 8" at school yard #4, an inch deeper than when I last posted. The signal was pretty choppy, however, which I have noticed can happen on some wheaties depending on how they are situated in the ground or how deep they are. I'll keep testing this setting to see if I can get similar results in other areas.
