I have a Deus with 3 coils, the std 11", the 9" HF 55 kh and the 9.5" HF elliptical 74 kHz. I plan on prospecting in the New England area where the gold is small. Would I be better of using the 74 kHz coil looking for gold itself, or using the 9" 55 kHz coil looking for iron and heavy metals figuring that gold would accumulate in the same places?

Deus gold prospecting
- Thread starter Jay80

Hi,
when you say small, how small in size and weight can you expect the gold to be? Are you mostly going to be prospecting with your Deus or using it to track black sand concentrations to pan or sluice? Generally, how big are your black sand particles?
Sorry for all of the questions. If you are expecting gold nuggets that are 1/10 of a gram and larger normally, you could go with either coil easily set on their highest frequency. I only have the 9"HF coil at the moment and it has hit a 1/10 gram picker down to 2" on 54kHz. It has detected larger gold, 1.5 grams, at 6" and I have dug similar and larger sized lead and brass down to 10". I did not get quite those results with the 9X5 depth wise when I had one for awhile. The 9x5 would add maybe and inch on the 1/10 gram picker and might pick up 1 grain sized gold flakes at an inch or so running at its highest frequency. It was much easier to get the 9x5 in tight spaces but either coil works great sideways too or you can just pull the lower stem out (be careful with the battery) and really get into some weird places.
I would use a little Disc IAR, maybe set at 2 or 3 to help identify iron. Iron signals will begin to break up and crackle at that setting. I wouldn't go much higher if you are looking for really small gold flakes or black sand concentrations since at least in my testing max IAR 5 cut down on depth for small gold a bit. If your gold is mostly small I would also be careful with reactivity. Leave it a 2 or at most 2.5 since a higher setting will definitely cut depth on tiny gold. Also if you set it too low it may miss small gold or mimic an broken up iron signal.
just my experiences, your ground conditions, gold purity and density could be different.......

Thanks for the info MikeLab and jmaclen. Unfortunately, I can't answer the question of gold size. I will find out next Spring when I get there, but the info you gave me was spot on. I plan to prospect with it, track black sands and look for iron, since iron is heavy and gold would accumulate in these places also. What program would you recommend? The goldfield program in all metal mode or a program with discrimination?
I definitely would recommend the Gold Field program for most of your gold prospecting. The settings I mentioned in my post referred to the Gold Field program. I have also had good luck with the Fast program using a little discrimination (just enough to quiet down the ground noise and knock out hot rocks). I would use 2 tone audio with iron volume on at a comfortable level. I had good luck with the XY graph since it was the easiest for me to see quickly so you could learn that screen in case you are unfamiliar with it. Most important, gold prospecting with a detector for really small gold takes a lot of patience and a much slower swing speed. If you have some small iron practice targets and some small lead targets (down to .25 grams or so) you could practice ferrous/non-ferrous targets separation, masking and audio characteristics while adjusting settings. The Deus at 54 or 74 kHz can hit targets the size of a straight pin head whether they are gold, lead, brass, tin or iron which can get frustrating. Practicing really helped me a lot.

I use the ORX, but the same thing should apply to the deus. First thing to always do is ground balance, I find the area I want to hunt, usually narrow it down to a 20 x 20 sq ft area, in that area I usually ground balance 2 - 3 times. I also go through each gold frequency, the 31,54 and 74khz. why each frequency, the higher the frequency the smaller gold, also the less depth, so I spend the time and get as deep as possible. You will also need to adjust the sensitivity , and reactivity, higher is not always better. depending where you are the reactivity will be between 2 - 3, mine is usually at 2.5, same for the sensitivity, I can not go higher than 88-89 or the ORX becomes unstable. MY IAR is usually at 2, once again every area is different, if you are looking for iron turn the IAR off. Then you want a threshold, mine is set between 4 - 5 , mostly because I am hard of hearing.
Gary B. has a good video on the DPR 600 which is a pre-ORX gold nugget machine but very similar. Use the Deus Gold Field program (basically the same program) and tune it like he shows. Some valuable info here. Learn to hear the Zip-Zip. Not a bad idea to read some nugget hunting books. Yes, where there is trash it means there were miners there and probably no one has hunted that spot with a detector. Bring a good magnet to pull out the iron and get a plastic nugget cup/scoop. You might even need a magnifying glass to see the smaller pieces. LOL Or just save it in your pouch and pan it when you get done. Some people find the black sand and then use a sluice to work that area.

Jay80,
as you can see BobOso and I use very similar settings on the ORX and Deus. We both hunt in the Rocky Mountains and desert Southwest. Your settings may be different, but what we're saying is a good starting point. Gary also recently did a Gold program video on the ORX where he had IAR set at 5 and sensitivity at 99. For small gold I would not put IAR as high as Gary had his set in the ORX video and in most of the gold fields out west you cannot run sensitivity that high. His settings were for much bigger targets in milder ground.
