Just want the main control box - in full recently tested working order ! Dont need or want anything else. ta

There is one thing that I never fully understood and that is why some PI detectors are considered good for Big Deep gold ( SD2200, 7000Z, GPX5000) and others are considered Small Shallow gold detectors ( SDC2300, GPX6000 & now AF-E1500). I get that for small gold you need a small coil &...

There is a little game I play when detecting, I call it – Where is the Car Now? Anytime I stop for a drink of water or a rest after digging a deeper hole I try and estimate direction of the car & distance without looking at GPS ,phone or compass then I check my guess vs my GPS and see how close...

Chasing a copy of Reeds Prospecting Booklet - Gold Book Vol 1 Eastern Gold Fields. I was in their store a couple of weeks ago & they were sold out. happy to pay a reasonable price, even more if it is well thumbed & you havent rubbed out your Xs :)

Tired of your detector falling over when you put it down to test scoops? Frustrated that your $1200/$8000 detector cant even keep its own control box out of the dirt? Your worries are over with the new patented rotating Detect-o-Stand All you need is : 400mm x15mm x 3mm carbon fibre strip...

Does anyone know: 1) How the SDC 2300 salt modes actually work ( electronically) 2) What variable is changing when you switch between salt modes 1, 2 &3 3) What using salt mode means in practice beyond "suitable for salt saturated mineralised soil conditions" ? 4) If I use it in low or...

Attached is an excerpt from the Qld Fire & Emergency Services Land Search and Rescue Training Guide. It is from the section of profiles of types of people they may have to search for. I went thru the dot points and, with the exception of the GPS/map/compass one ( I ALWAYS carry those), I...

I want a combined VLF & PI detector and I really don't see what the problem is ! I am thinking 2 completely separate detectors in the one unit so I can use the PI where I can but when I find a trashy area I can just flip to VLF, or if I just want more info about a target before digging. 1...

At the risk ( certainty?) of adding fuel to the fire, I went out last week and spent a whole day just testing. Results attached & some of last years testing results in same spot as well. What the results dont show is how stable each detector was over the ground in the area. The GB numbers show...

Does anyone use the largest coil on their Kruzer/Multi Kruzer/Gold Kruzer - ie the 15x14ish DD coils - KR40 or GK40 ? If so what is their experience - How does it handle mineralisation & does it significantly improve depth or is it just for covering more ground in parks,beaches etc?

For Sale - 6m old set of Sunray Pro Gold headphones. About 10 hrs use. Near new condition - just cosmetic scratches on one cup. Definitely better than my UR-30 but I found I much prefer earbuds. Paid $210 ex USA. $125 price inc postage in Oz.

Used some stiff cable wrap to tidy up coil cable - came up well. Only 50g/m and $3/m. About a minute to wrap on. Stiff enough to protect cable & shaft against bumping on rocks & picks. Probably suits those who dont change coils often or keep their coils with shafts on. If you buy some the...

As I posted in Feb, I bought a NF 14x9 Evo at the end of 2019 & initial air tests were very promising it was as sensitive as the Sadie to small stuff and could go way deeper on big stuff. Air test : Both with 16V battery, 10us, All, 8 gain, 8 GB, 320Ohm phones. Sadie is 1st number, 14x9 Evo...

Just curious if anyone has ever done a head to head comparison of a QED and a TDI - depth, & ground handling in exactly the same ground ?

Chasing a reasonaby priced 2nd hand ML 10x5DD....

Chasing a secondhand small DD coil no bigger than 6". Is for a Whites TDI SL so a ML pinout needed.

This is a question for those with both a Pro Oz and an SL like Karelian & Ridgerunner. I have often wondered, Does the fine GB control makes a significant diff or not to being able to properly GB the machine in hot ground? The reason I wonder this is because I notice that with my SL in mild...

When I first got my TDI SL I used an old pair of 32 Ohm Shure hifi headphones. Worked fine but cord was a bit short when trying to put the detector on the ground. Last year up in Clermont, from OBP , I got a pair of 100 Ohm Koss UR30 Minelab SDC headphones terminated with a 6.5mm right angle...
