Detecting with zero disc

[Cal_Cobra]

When people post their settings (which is very helpful) I see that the majority of people are leaving the disc setting at 10, a few will lower it to 5, and quite a few will actually raise it.

I'm planning to detect a "hunted out" site this weekend that the Racer has done very well at, but to be honest my bag of tricks is about empty, but I'm sure there's more coins at this site, so I'm trying different angles to get at the goods.

First time I hunted there with the Racer was with the 11" DD coil, 3-tone, disc @ 10, sens @ 70, then increased to 98 and the results were four old coins.

Second time I hunted there with the Racer was with the 5" DD coil, 3-tone, disc @ 10, sens @ 98, and the results were nine old coins.

I was impressed with how well the 5" coil does there. I think the next hunt there will be with the 5" coil again, and I'll reduce the disc to 0. I have seen a few videos whereas targets reported as iron with the disc at 10, but dropped to 5 or less, they reported as non-ferrous targets. There's not a ton of iron at this site, but there's apparently enough that at this point my F75 sees no coins, whereas hunting exactly the same spot directly after the F75 with the Racer using the like sized coil produces coins.

Any other settings that are helping people find coins at their hunted hard sites? I guess I could try the AM mode....have never really liked hunting in AM, but might be a good site to try it on the Racer.

Thanks,
Brian

Cal: Isn't running discrimination at zero essentially the same as running in AM?

I see what you're trying to is uncover more targets that this and the other machines have missed. In DI3 you'll be able to do that but will have to listen carefully. It will still give you the 3 tones but you'll have more mixed in let's say. A lot that you really don't realize at this point I'm thinking. Also you'll probably hear a lot more falses would seem like. Maybe I'm wrong but what the heck give it a whirl. The small coil is very slow hunting but well worth it for me. At 98 sensitivity it might be for a lack of better words washing some of the targets with so much noise from the other stuff it's seeing I might would go the other way to the extreme like 1 or 10 sensitivity. It's still going to see the stuff not unless it's super deep for the small coil but it will give you a more subtle report to dig by. Remember gain and sensitivity are in conjunction with this machine.

A couple things, First going down lower in ID filter helps a little with depth. I've seen this in f75 5 bar soil. Next in the worst of sites there's a chance a lower id fitter setting may let more/longer tone through allowing the user to hear it.

Bey - You still get your three tones vs AM monotone, but you'll hear everything with no audio masking. A higher discrimination can mask out co-adjacent non-ferrous targets next to ferrous targets. Also targets at depth on most machines tend to TID as iron, a lower disc setting can help the machine report these fringe targarts as non-ferrous. This is how I hunt with my F75, 0 disc, max sensitivity. Now the nice thing about the Racer vs the F75, is that the F75 tends to average co-adjacent targets, but the Racer tries to report everything it sees under the coil. This conveys a lot of audio info.

Jack - Good points, I'll try to go slow and once I get something, I may try adjusting the sensitivity to check it's reaction to a lower sensitivity setting.

squirrel1 I completey agree.

Thanks & HH,

For me the 5x10 coil is the best..second if a lot of iron and trash don't use a high gain lower it to about 50 or as low as 30 if real heavy iron. We may think all the coins are deep but it could be they are not that deep and are being masked..And I only use 2 tone and can hear more. It's make my racer sing on all targets for me and what I like...as far as disc the less you use the more you will hear and that can be a lot of mental stess if you are in an are with lots of iron and or trash. I would use 5 and just keep my ear ready for and tone that repeats and is not an iron tone. You have to slow it down a bit and it takes a lot of time and wear and tear and can make you want to move to a new area. But that is the way it is done for me and I have been finding a lot of nice finds this way...
