  1. Thanks for posting that Gerry, I had no idea NC had a significant amount of gold deposits, here is an interesting historic reference about it - there still might be some really big lunkers just waiting to be found out there!😉 “The first documented discovery of gold in the United States was in 1799 at John Reed's farm in Cabarrus County, NC. John Reed’s son, Conrad, found a 17-pound gold nugget while fishing in Little Meadow Creek. This discovery started the first gold rush in the nation's history.” https://gastonlibrary.libguides.com/gold
  2. I’m glad I didn’t put the cable in the back of the box on my GM! 🤔I was just teasing, good job on the video, I’m looking forward to trying to see one in action as I’ve never even seen a original one working. Oh and by the way, I’m a fan of your book - thanks for all the work you put into that!🤩
  3. Hey Chris, great intro to the GB2. Thanks! I know the questions been asked probably a zillion times, what do you think its performance is on depth while using approximately the same sized coils compared to say a GM 1000 on the same sized nugget that both can detect? Ha, I think you had the control box mounted on backwards, you kept saying the end with the display and controls is the back of the box! 😉
  4. Be careful with inexpensive inverters, the cheap ones try to simulate an AC current by using a square wave and they have been known to blow out sensitive electronics and charging units. They should only be used to power AC motors. A pure sine wave inverter has more of a true AC current. That’s why you see “filtered AC” power outlets on boats and other commercial vehicles for powering computers and other electronics. Pure sine wave AC inverters are more expensive than simple unfiltered square wave inverters. It would be much better and safer to use the 12V charger instead of the 110 charger with an inverter, as mentioned previously, there is less waste of electricity because you are not converting 12V DC to 110 AC then back to 7.5V DC in the charger.
  5. I made this 12v 35Ah (420Wh) portable power battery with left over parts, but you can do it for $100 to $250, depending on options you want, such as solar charging, vehicle charging vs. 120v charging, adding a 120v power inverter, etc. When fully charged, it runs our refrigerator for a day and could provide about 6-8 charges for GPX-6000 batteries without drawing it down too low. The battery is based on a low cost 12v 35Ah deep cycle gel cell made for mobility scooters and trolling motors like this: ML35-12 - 12 Volt 35 AH SLA Battery- Mighty Max Battery Brand Product https://www.amazon.com/dp/B00K8V2VD0/ref=cm_sw_r_cp_api_glt_fabc_5R2WR55KHZYEF1202G21 The Renogy 20amp DC-DC battery charger lets us charge it from solar panels and from our truck batteries- it will automatically charge when the truck is running too: Renogy 20A DC to DC On-Board Battery Charger Flooded, Gel, AGM, and Lithium Batteries Using Multi-stage Charging https://www.amazon.com/dp/B07Q5VYPCF/ref=cm_sw_r_cp_api_glt_fabc_YD8N92AHJP683K2SA7HH?_encoding=UTF8&psc=1 The case is a $9 HF plastic ammo box with a built-in handy cover storage area for cables, connectors, etc. I cut about 1/3 off the side of the tray and used it to mount the switch panel and 12v and USB charging plugs to: https://www.harborfreight.com/tactical-ammoutility-box-64113.html And I added a switch, voltage meter, USB power plugs and a cigarette lighter plug port like this to it: Linkstyle 4 in 1 Charger Socket...

Just PM me if interested. -Anthony
  6. Off-roading and EV’s means a lot of waiting around in the daylight doing a lot of nothing (prospecting?) while the sun does its stuff!
  7. …and running a 100w solar charger all day will replenish the loss of charging a couple 6k batteries on your truck battery.
  8. I don’t have a GPX-6000 (yet), so I was going by what both Rob and Jerry said about it’s rating, it looks like Rob is advertising that battery as 100Wh. I was a bit surprised about that because it would be a pretty large lithium battery (My drone batteries are 60Wh and they are twice the size of a 6000 battery). So if it were true, that 500Wh Jackery of yours would not last five charges because you wouldn’t want to run it down to zero. 25% is a good stopping point which would only give you about four charges if it was truly a 100Wh battery and about twice that if it has a 42Wh battery rating. 42Wh does make more sense, what is the output voltage of it?
  9. I have a 2017 Tacoma as well. I run my refrigerator as described earlier. Yours will require the most power of all the devices you listed. If you want that to run continuously day and night, you will need batteries that can keep up and a way to recharge them. For starters to determine the minimal battery capacity, what is the peak power consumption rating of your refrigerator?
  10. Gerry, if you do decide to go with a dual battery setup for your truck and want to DIY- all you need are battery cables and a automatic charging relay which will keep both topped off when your truck is running, then attach the solar charger to the second battery in camp and use it for charging the detectors or other items- that way your main battery will always be full. The Blue Seas ACR’s are marine grade, here is the model I put in my truck- If you do install it all you need to connect are the two batteries and the single ground (from the middle terminals), the LED and ignition isolation pins don’t need to be connected: Blue Sea Systems Automatic Charging Relays (ACRs) https://www.amazon.com/dp/B000OTIPDQ/ref=cm_sw_r_cp_api_glt_fabc_75WY5FKHAG7VWT2M8JKM?_encoding=UTF8&psc=1
  11. Gerry, there are a couple options you could use. A 100w or 200w solar panel would keep your truck battery topped off if it is parked the whole time you are camping and will accommodate detector charging or running a small portable refrigerator for a couple days…. I put in a two-battery system on my truck and use a folding 100w suitcase solar charger around camp. There are many different solar panel brands out there, just be sure to consider getting a deep cycle for the second battery you are charging from as it will allow for more charging cycles.

  13. I was a raft guide there in the 80’s. We had a group of musicians playing blues in camp one night next to Briceberg and a miner came off the hill to join our little party. Nice fellow who went back to his place and get his gold from the season to show us- he had a large mayonnaise jar full that he dredged from his spots nearby the bridge. Wow! I never saw or held such a heavy collection of gold. Sure was pretty too, and it was mostly coarse stuff. I can see why it brings such excitement to the finder!
  14. The worse - present in every place detectorists go as well!
