threads a bit old but hopefully that means you have even more time to play with the Manticore Nenad. I was wondering how it compared to the Nox 800/900 in terms of gold depth and ground handling ?

The now unobtainable Whites TRX is one of the only true pinpointers - it only detects in the forward direction from its nose. Most other pinpointers also detect strongly to the side of their head - sometimes upto 50mm up the side . So if you are not aware of this you can still go off track...

Thanks Matt, Spot on with the type of info I was looking for, hoping Nenad can verify or otherwise. Yeah I was only thinking about using salt mode on a last resort basis but it is better to know beforehand what the likely impact is - it is one thing to get a more silent machine and still...

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...

From some of Reg Sniffs old posts on the TDI detectors, for coils over 20" he recommended using 15-20us delay and High mode. Now that is for deep large gold ( max 2x coil diameter deep) so you would need to see if bigger deeper iron gave a reasonable signal in High or not.

So the differences are mainly cosmetic - what is inside the boxes is exactly the same. The Miner John coil is better than the standard Whites one for AU gold hunting. It wont be better than a Sadie on small stuff though but it will def go deeper on larger targets.

Damn right you would be happy with an ounce a week even now ! At AUD$2900/oz that is $150k pa. For a long time in the 1800s & into the early 1900s an ounce a week was considered perfectly acceptable wages for a hand miner.

Given that the 6000 was only released a few years ago, and so many experienced detectorists have traded (up?) to it & it is still selling well for a detector at that price point , I doubt another new PI release by Codan is less than 3 years away. Fixing 6000 reliability issues is probably...

No personal experience with coils larger than 18" on TDI but if you are considering DIY coil building of any size then https://www.geotech1.com/forums/forum would def be in your must read resource list.

Totally agree with your review. I have had a Garmin InReach for +4 years. It lives in the 4WD & then in back pocket when prospecting, boating, flying etc. Limited functionality but it does the key stuff well ie global SMS & location tracking, long battery life, very small size...

There were very very few sources of information in those days. Papers were read front to back and important life changing decisions made based on them. The role of paper journalism in creating and maintaining a community was taken seriously. A single 3m old paper from Melbourne might be the...

Perfect, as long as you have ensured the power rating is about double what the power draw is. I have had a couple of ebay buck converters like that let the magic smoke out at under their rating, but with sufficient overrating you will be fine.

So total cost would be something like BAT01 Admin $42.90 per batch + for each sample: LOG22 $1.75 DRY21 $1.30 CRU32 $4.05 PUL31 $7.85 Au-AA25 $22.45 or (Au-GRA21 $33.75) depending on grade so looks like $43 per batch + $40 per sample. thats really great and I am amazed ALS will do that price...

Arsenic(As) is extremely closely associated with iron pyrites often at a level 10,000x the gold level & if it is present that will overwhelm the gold signal for XRF. No harm in trying though but wont know for sure if the reading is a false positive or not until do a fire assay. Also it is all...

Depends what you think is a reasonable cost - a few hundred bucks per sample ? Doesnt sound reasonable? well if you want to do it yourself then you could grind it to powder in your dolly pot, heat it in a carbon crucible with a butane flame until all the sulfur is gone, cool, grind it again...

I think you have done very well - PI coils do not need as precise setup as VLF ones as in mainly the one coil for TX & RX but you have made a working detector and that is huge. In VLF & IB coils a seperate wire is sometimes used to help balance but the details are beyond me. Best resource...

Not sure of your level of detecting experience so this may be a a bit Duh ! but smash it ! - pref in a dolly pot. If signal now only in one piece or a couple but equally strong as before or stronger then keep working it smaller. If signal disappears or is present in lots of the pieces...

Phone may or may not open it well, use PC.

Clermont, Etheridge Shire, Palmerville..... for Queensland you are in the perfect spot to get to the main publically available spots

The answer is YES... Ridges AND Gullies Gullies, as that is where the gold ends up concentrated as it washes down so they are the obvious 1st choice but because they are obvious and very well defined - often only a metre or 3 wide and easy to walk up as there are generally less vegetated...
