Late series GPX4500 running DD but otherwise normal settings, RX Gain 12, Stabilizer 16, Target volume 1, Volume limit 2. I would normally run Enhanced for the Mono coils but I set that to Normal because I don't know much about running DD. I ran it on Fast Tracking too but I would normally be Fixed.
I'll tamper with settings more once I get away in the bush on good ground.

Redfin, just adding to that. I've not modified the GPX4500 at all. I just undid the coil cable and slipped the lower shaft out. The upper shaft slips down the centre of the poly pipe so if I want to use the 4500 normally it's as simple as changing the coil and adjusting the settings.

Hard to say if it will be really quiet because I had too much storm activity and strings of trucks passing because the highway had only just opened after being cut by flood water. I was getting a bit too much noise through so had to minimise the threshold but I tried a few times cutting the engine on the quad and it made absolutely no difference. I was travelling down a track through my lease and watching the speedo at 10k/hr when I picked up the 22 bullet shell. I was really pleased with that because it was a clear loud signal and I had the threshold low enough that I could just faintly hear the chatter. I have my harness with the battery in the back toolbox and the Grey Ghost earphones on maximum volume. I picked up a ball headed boot tack too when travelling at about 5k/hr but I also pulled out a few flakes of rust with the 6000 so I'm not sure what gave me the signal.

I bought new tyres for this season. It's a bit difficult because I still have four of the last six tyres still serviceable. If they'd been good tyres then I could have just bought another two and we'd be back to six good tyres.
We lost one on a hot day returning from Perth and the last on the long stretch of remote highway near Sandfire Roadhouse just as a storm hit. We need super singles for the type of bush travel we do but they aren't as good at carrying a load when the temperature gets over 40°C. Duel wheels carry more weight but we find that we end up with a rock stuck between the rear tyres whenever we're offroad. The other issue with these Hankooks is that they come from a Queensland dealer who fails to honour the usually warranty.
I called the local workshop to make an appointment to have a couple of tyres fitted to find that the mechanic had left and closed the workshop.
This left me with the option of a two hour drive to a nearby town or try to change a tyre by hand. The first challenge was to break the bead and that nearly proved too much for Zimba our little excavator.
Of course that was only part of the challenge. These tyres are too rigid to easily insert the tyre lever.
If you head well off road and you don't know how to change a tyre then this is one maintenance procedure you probable should learn.
It took me about an hour to change this tyre but it was still quicker than driving off to a neighbouring town and hoping to get decent service.
It would be extremely difficult to change tyres like this in the bush but everybody who takes their vehicle into remote locations without a support crew should know how to carry out this sort of basic vehicle maintenance. It could save your life.
The Hankook 37x12.5R17 tyres had a load rating of 129Q 1850kg at 65psi. The new Renegade 35x12.5R17 tyres have a load rating of 135Q 2180kg at 80psi.
There are still five to go but I could only buy four at the time and I decided to stick with the Hankooks for this next trip and take a Renegade as a spare.

Looks like hard work.
How would you break the seal in the scrub unless you were towing an excavator?
You could drive -carefully over the tyre to break the seal.
How would i drive over it when it is still on the car?
You would have your spare on first-wouldn't you?

I have driven over a tyre to break the seal but it doesn't work too well. The other side fills up with dirt in the bead and so beads lock on so tight that they simply won release that way.
There are some commercially produced bead breakers like Tyre Pliers that I should own but have never bought. Nightjar has designed a bead breaker for use in the bush, I'll try to find a link. Other than that a high lift jack can be used with the foot of the jack pressing into the bead. However there's no easy way, changing a tyre on anything but a split rim is likely to set you back quite some time but if you've done it before and know that you can do it then you have a very good chance of success.

I've never seen this one but it looks like one I'd like to own and it's designed in Western Australia
Looks like a wanna have for sure.I've never seen this one but it looks like one I'd like to own and it's designed in Western Australia
To break one bead I use a piece of suitable hose then find a vacuum port
on the inlet manifold of the motor. Past the throttle body.
Start the motor and let it idle sucking the bead off one side. Only leaves one side to do battle with.

Lately the dryblower has been giving us some really nice water warn gold, not bad for a dry ridge in the desert.
But today was different. I had limited time because I'd promised to get down to the CRC (Cue Resource Centre) by 10am to put up some sheets of weldmesh. I arrived at the minesite just on sunrise and after carrying out a few minor repairs I commenced to scrape up some dirt. I can only scrape surface dirt at the moment because the deeper soil is still too wet from the recent rain so each day I'm on a new spot.
I've been going well on my panning but today this was the best I could do. Whatever all that is mixed with the gold it was quite heavy so wouldn't separate in the pan. A couple of days back a lot of the gold came out coated in mercury so I had to hit it with a bit of heat and and the mercury disappeared so I tried that again today but the problem wasn't mercury.
I decided to melt it in a crucible with a bit of borax and it cleaned up quite well only it looked more like lead than gold.
It weighed in at 11.18g when I was expecting three or four.
I recently bought some cupels so I added a few grams of lead and hit with the oxy torch.
The cupel absorbed all the lead oxide and left me with a nice little gold button.
The molten pool in the cupel should flash over once all of the lead has been oxidised but that didn't seem to happen. Anyway I'm quite happy with the end result for my mornings work.

Nice display of gold in the tray.

Same again today.
The difference today is that I also got bigger chunks of lead in the classifier.
And the melted out of the crucible is twice the weight. I might not bother to cupel it today and wait until I have another one.
