I'm not the best person to ask, being I'm a Goldbug 2 user. I do own a Pro too and have used it in AZ and CA. So just going with the basic advise, start out with the 5" coil, go slow and dig all targets. Make yourself some test targets and bury them a inch so you can get your ears use to the sounds they make. I run in all metal mode and ground balance often, sometimes every few feet or so. At first the hot rocks will be a hassle but as soon as you get them figured out you shouldn't have any problems. The Pro will find the small gold too so make sure you go slow and dig all targets. Looking forward to your claim report and good luck.

I own a Gold Bug pro and use it alot but it is very hard to use in or around wet alkaline ground. Its very easy to setup. I have a 6x 10 elliptical coil which works great. The tip is very sensitive to pinpointing. dont run the sensitivity up too high, not past 70. It just starts getting to jumpy. Air testing with it doesnt actually replicate how a piece of gold will be in the ground. One thing to be sure is never run your detector with the cell phone turned on. Not good. I like that its very light and can be ground balanced easily. As your running the machine you can read the ground and when it changes, just readjust to match.

Thanks for the info. Looking forward to playing next week.

Hi Guys I just bought a Gold bug pro also. I have been watching YouTube videos on how to use it. I live in central Minnesota where the ground is frozen and there is about 14 " of snow on it. I want to prospect in the black hills in south Dakota this year around deadwood Spearfish area. I have been there many times during the Sturgis rally on my Harley's. Never prospecting there though. I like fly fishing also in the creeks out there as long as there's no cyanide poisoning from the old time miners. I also have a self contained power gold pan that takes 3 gallons of water and runs off a 12 volt motorcycle battery and a solar panel. 🛶

I read a reply from Leo that I should not have my cellphone on using my Fischer gold pro. I also have a 5 watt vhf uhf ham radio that I use and a GPS unit. I don't know if I can use these now?. I am off road alone a lot in the Minnesota and south Dakota back woods where cellphone service doesn't work my ham radio does. Hate to not have it on while metal detecting. 🛶

A cell phone is a transmitter, and when turned on, it does communicate with available cell towers, and it does cycle transmit as it stays synced with the towers. Its best to not use. even an aircraft flying overhead can cause interference. Its more pronounced with PI detectors, and I noticed issues of random noise with the GB Pro as well

EMI, EMI, EMI EVERYWHERE!
Electro Magnetic Interference is everywhere! It is a topic I have spent years studying and countless hours talking about in Seminars. Everything from your cell phone to a jet overhead can and will create EMI and it can and will affect your detector.

I always use a story when I am talking about EMI. I was working on testing a detector with a couple of the engineering team a long time ago when I realized that I knew that my phone was going to ring seconds before it would make a sound. I could hear the interference in the detector as the call was setting up in the phone. In one area it had gotten so bad that I had enough time to stop detecting, pull off the headphones and reach for my phone right as it began to ring. NOT GOOD. The fix was simple enough from their standpoint, increase the filter response. But that made me think about something Filtering in not removing everything. I have a great water filter, water goes in and cleaner water comes out but only a certain + or - %.

So even though EMI is reduced is it totally eliminated? No it is not and there are so many forms of EMI that you cannot get away from. what you can do and should do is mitigate the EMI in your little detecting bubble. Turn off you phone. I do this cause detecting is my time and in most of the places I detect, it does not work anyway. It is a false sense of security that if I need it, it will be ready to go.

I carried a emergency location unit for years and am upgrading to a GPs that has a built in SOS system and the ability for a responder to find me if I ever have to hit that button. And being that it is a GPS as well, it makes it easy to mark my finds and trend my areas when I turn it on. And yes there is a subscription fee but I think of it as insurance. pay for it and hope I never need it until I do. Little off topic though, sorry.

Aircraft especially Military drives most detectors bonkers and there is nothing you can do about that except stop detecting for the short amount of time that you are buzzed by EMI. There is also a huge amount of ground/tower based EMI from wireless links, cell towers, broadcast and everything else hidden in those carrier waves. The best defense is to be aware of it, mitigate when possible and know when it is effecting you.

Where in Arizona? I'm in Prescott.

I will be at Vulture Bait Friday, Sasquatch saturday. Not sure on sunday yet.

GP???

GPS. I carried a SPOT with me for years along with my GPS. I've retired the spot unit and have upgraded my GPS to a Garmin inReach. https://www.garmin.com/en-US/p/561269
Still have emergency access and a perfect for me GPS al in one now.
