Hey Tony. The TDI's pulse delay and ground balance controls work together. On certain targets in certain ground you might find that a perfect ground balance setting diminishes the target response. This is due to the fact that at that particular setting, the ground balance point effects the machine's sensitivity to that particular target. Some people call this a "P.I. hole" or "ground balance hole." It's good to do ground testing to find out what effect it has on targets with different ground settings. One thing you can do when a target falls into the "ground balance hole" is adjust the ground balance slightly higher or lower to increase the sensitivity of the machine, or adjust the pulse delay to hit harder on that particular target.

That's an old yank phrase from the gold rush days. Blokes would head to California to "see the elephant." Elephant in this case is our new gold detector, the Goldmaster 24k.

Hey guys! White's Electronics will be attending the Rye Patch Nugget Shoot this weekend. We'll be donating a Goldmaster 24k as a prize at the event. Also, thanks to the team putting this on we will have a test garden at the event to demo the Goldmaster 24k. This is where you can get your hands on it, swing it over buried targets, and maybe even find some real gold! We won't be renting an airplane to skydive out of, but I may tuck and roll out of my '96 Suburban for the sake of showmanship. This event is free to the public, put on by the GPAA of Northern Nevada, Parks Department, and other groups. It's one of my favorite organized hunts in the USA. More information. Here's an idea of what the event is like (video from 2016) -

That is really interesting! First pan had lots of tiny quartz in it so I will assume the clay is made up of that since it's so white. I think I will get a grout/mud mixer and haul a drill out there.

I found some good gold in clay. Sticky, greasy stuff but shows promise. So I ask you old sourdoughs, what is the best way to process this material? I have been smooshing it by hand and then panning but it's not very efficient!

The AF108 is a PI detector. Ships with OD green harness. Will be a great collector's item or prop for a movie!

Sometimes there's enough iron in serpentine to make it jump onto my pick magnet! Might be worth a check.

We ship directly to a few dealers in Australia, not just one.

Here's a link: https://www.whiteselectronics.com/product/tdi-beachhunter/ Performance-wise our field testers have told us it's in between an SL and Pro. This is likely due to the hard-wired coil being more sensitive without the connector inline.

Still working out the details.

There is detectable gold up the Calapooia, Quartzville Creek, and then lots down in the Grants Pass area. But there is a lot of private/claimed land and the residents of Jefferson can be strong enforcers of claim boundaries. Best bet is to do research and scouting before detecting as online info can be inaccurate sometimes, at least in my experience.

I think I smell a TV show starring Gerry. Coming soon on the DIRT NETWORK...

I have a couple of these printed packs. They will fit in the case with some modification. So will the super hot 16v battery pack I have. Officially White's can't endorse a 16v battery due to the increased chances of component wear and heat generated by the large caps on the board. The 18650's diameter prevents use in this waterproof case without a slight modification (2 minutes of Dremel action) on the inside of the case. This may void your warranty. The 14500's have the right size to use in a battery holder but usually come out about 750mAh. You could do 4 x 2, get 14.8 volts out of it but only have 1500 mAh. Less time to hunt than the OEM pack. All of these things are options for intrepid DIYers, but our goals were 1) release this in a timely manner before the competition 2) keep the price of the detector reasonable and 3) don't push the hardware to the point of failure. I know it's not ideal, but at the worst you can carry an extra battery in a waterproof case or baggie with your wallet/keys/phone. And at least you will still have a nice deep seeking PI before fall of 2018. This project is more of a "Huh, that's a good idea. Why wasn't this done before?" vs. making a huge engineering project out of it.

That is a good note. This was a one-man-band setup, no script - camera on tripod was my only friend. But I should probably do a better job of listening back to make sure I get everything right. Next time!

Most machines that have a single ground balance point will balance to a combination of what's under the coil. White sand usually lacks the type of minerals detectors look at for ground balancing, so I would guess that you will be balancing out mostly the black sand. Here we have some difficult beach areas with black sand, basalt rocks, and then of course the conductive salt. Definitely pulse territory!

Gosh, it looks like we do have a waterproof TDI after all! Ships with a Heavy Duty battery for longer run time and also has increased sensitivity and stability due to the hardwired coil. A bonus we did not expect! Want a mono coil? Coiltek? Miner John? Etc? We are working on setting that up in "White's Custom Shop." Or if you are handy you can DIY (note: this will void your warranty). Sorry for not having more info earlier. We like to tell our dealers first and wait until products are ready to ship. Now excuse me while I jump in the Klamath River and find some nice nugs in the bedrock. https://www.whiteselectronics.com/product/tdi-beachhunter/ White's TDI BeachHunter Specifications Operating mode. . . . . . . . . . . . . . . . . . . . . . . .Pulse Induction Pulse Frequency . . . . . . . . . . . . . . . . . . . . . . . .2.6kHz - 3kHz Pulse Delay. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .10μs - 25μs Search modes . . . . . . . . . . . . . . . . . .

Here on the west coast the difference between a TDI SL and Surf PI is about 4-6 inches on a gold ring.

There are some interesting things that happen when you hard-wire a coil directly to a board. Kinda like running headers to straight pipes on a small block....

And here I am stuck in an office...

Hey guys, we are hoping to have a white paper write up on XGB soon. We don't want to give too much away, but basically it allows the machine to track more than one ground balance point at a time.

I didn't mean any offense, and I would like to think we've learned our lesson as a company. As to that picture...

I don't see a waterproof TDI on our website. Can you post the link?

Aw shucks! It looks like we had a glitch on our website. A waterproof TDI is a great idea! But unfortunately we're not at liberty to discuss current projects, etc, etc... I've heard that one of the other manufacturers was working on a waterproof pulse induction machine, maybe you guys have White's Electronics confused with them?
