SDC Experience

[Redfin]

Well done DM, $160k with a $4400 machine, gotta be happy with that

SDC is an electronic panning detector a majority of the pieces found might be small/tiny but they do add up quickly. I have hit some good patches with SDC one was at bonnie-jean track surface areas at daisy hill. Each photo is a full day of detecting. But I have sold my SDC for $500 recently so I can spend more time using the 6k.

Like nenad I run on sensitivity 1. lowest threshold 3 which is good when working a patch of crumbs, 4 threshold general searching just so its a faint hum then using a generic booster (nothing flashy) increase or decrease that stable hum to preference depending on ground. Its like an extra overall volume control to the SDC. I have found and paid for my SDC 38 times over which might not seem like much to 7 days prospectors. I still used standard headphones so I don't think the headphones really make much of a difference to overall target performance. The only time I increase SDC to 5 sensitivity is to do EMI cancel check as it helps enhance the EMI source then do the cancel and afterwards switch back to 1. I also keep my coil semi-floppy not too tight as its easier to glide perfectly with ground contours resulting in a more thorough ground coverage.

Well I guess everyone is different just about 90% of the people I run into in the bush run on 5 SDC sensitivity its to get better depth they say haha lol. But maybe there is also a different reason behind it so I thought I better ask the question in here.

I did some depth testing of my SDC a while ago & whilst 5 sensitivity gave about 10% extra depth over 2 under controlled conditions , I personally found 5 too chattery and doubt I would get that extra depth in real life.

Maybe I just need to spend more time at 5 and get used to it.

I don't worry about depth as targets are buried at random depths all across the goldfields. I mostly just concentrate on hearing the slightest change in threshold. I need the threshold absolutely smooth and stable and that's why I was on 1 sensitivity on SDC. In fact I'm still on 1 sensitivity on 6k. I usually detect for 10 hours - settings need to be pleasant for the entire prospecting day experience and at the end of that day I don't have a sore head, ears or can still hear the detector bleeping on in my head when trying to watch TV at home.

in the right hands, good machine

Only had the SDC for a few yrs but it was my first and is my most used detector. I can't run SDC on anything above 3. Far too chatty and susceptible to interference I think and I do think you miss those very faint signals. I agree with comments above on less is better, as I've found quite a few bits under 100th of a gm with settings on 2 and 1 & volume about half-way when there's quite a lot of interference. I have good headphones which helps a lot.
