It looks like you've done it, I guess you could use one of them multi tools to cut the overhanging stuff off before removing it from the mold?

I cut an old piece of PVC storm water pipe that would be good enough for a project test. It has a diameter of 90mm and a wall thickness of 2mm. Unfolded, it would give me more than enough material for the test plate but its thickness is just a fraction more than what I’d hoped for. The standard skid plate is 1.5mm thick so I will end up with a slightly heavier result. I’m hoping it won’t impact on how it fits or its performance but time will tell. A jig saw was used to cut the pipe down its length. It was surprisingly simple and only took 5 seconds to complete. A heat gun was used to warm the PVC and and slowly bend it out to a reasonably flat sheet. I began heating along the length of the pipe on the opposite side to the cut and this then allowed the PVC to be opened out into a sort of “M” shape. Heat was then applied evenly over the material until it sat reasonably flat. This process took a few minutes to achieve. A circle was then cut out to a diameter slightly larger than what was needed. The material was also given a bit of a clean. Three screws were placed into the ring mould to position the blank and allow it to be heated. Keeping an air gap helped to prevent a heat sink situation from forming. The hot air gun was then used to heat the entire blank before the plug was pushed into place using the lathes tailstock centre. Cramps were then applied to force the plug further into the mould. The heat gun was used to continually apply extra heat to the tag ends of blank as pressure was applied. You can see the corrugated effect that resulted on the outer edge of the blank.

September 29 2002 Part Two We Hit The Big Strike We are stockpiling gravel in piles according to their depth. That way we will know we are running the lower gravels and work our way up. It’s basically a high grading operation at this time. Around mid afternoon I heard the excavator bucket strike something very hard. Everyone came over to the pit to have a look. Jacob hollered to us that he thought he had hit bedrock. He tried to get deeper in several areas but was just scraping the hard bottom of the glory hole. Jacob said “We are there boys” and let his machine idle. I grabbed two five gallon buckets and placed them in the excavator bucket and I stepped in as well. Jacob slowly lowered me into the deep pit. The walls were smooth and nearly vertical. When I got to the bottom I filled them with gravels right off bedrock and Jacob raised me back to the surface. We classified the material through a quarter inch screen and then Jacob and I started panning. The black sand was heavy and so was the gold. When we finished up the panning we poured all the gold into a pan. Everyone was quiet as we set it on the scale. We figured the two buckets made about 1/20th of a yard. When I saw the numbers on the scale I couldn’t believe my eyes. The entire crew let out a holler and a cheer that probably was heard in town that night. Jacob said that yardage doesn’t mean a thing when you’re at the bottom of a glory hole. And he sure was right. There were .8 ounces in the pan from those two buckets. That figured to 16 ounces to the yard. We had finally hit the jackpot. TO BE CONTINUED ................

Totally agree, we started tent camping on Tybee Island near Savannah, this is my 5th RV. First one was 16' 🤣

It's sorta like it raining before metal detecting, it's sometime enhances the signal, with the wet mop it connects you to the floor better. I actually learned that as a youngster doing things my parents called "chores" back then.

FWIW, I ran my 800 at recovery 4 almost all the time. Never above 5. Testing on in the ground targets - my coin garden but they've all been in the ground at least 15 years now - I found I actually get better dig me signals with the Manticore at 5 or 6 than I do at 4. And even more so with the update installed. Absolutely not what I would have expected coming from the 800 and just one of the reasons I'm one of those who say the Manticore is not just a beefed up Equinox. It really is a completely different machine. Speaking of the update... Running the Stabilizer on, at 1, I can squeeze a number or two higher sensitivity. But I generally don't like what it does to the audio even at a setting of 1. I never use the Stabilizer Filter - I hate what that does to the audio. But I'm trying to get used to using the Stabilizer on, at 1. Still kind of early for me with that to have a strong opinion. Other than, I can go a notch higher sensitivity and maintain stability, which is why I'm giving it a go. - Dave

I was keen to finish making the female section of the mould so I got up early and mounted the blank to a faceplate. The shaping only took about ten minutes. MDF machines easily with lathe tools. The internal diameter was made slightly larger than the diameter of the plug. This was done to allow for the wall thickness of the skid plate. I will fine tune the size when I know the thickness of the plastic that will be used. You may also notice that the leading edge of the mould was chamfered and then rounded slightly with abrasive paper. This will hopefully allow the soft plastic to form into the mould gently without grabbing on a sharp edge. I drilled a few holes through the base to allow air to escape and also to provide a few areas where the skid plate could be knocked out of the mould from the back. That’s basically all I need. The plug that I made yesterday will be forced into the mould using the tail stock of the lathe to apply pressure. I may also have to use G cramps to force the soft plastic into shape. I’m not exactly sure as to how much pressure will be needed until I get to the next step. It’s Sunday morning here so the shops will be closed. I may have to buy some plastic sheeting online but I do have an idea in relation to using some PVC pipe for the experiment. I’ll have a play after breakfast to see what can be done.

And yes, thanks for making that differentiation! I kept saying “truly masked” in my original post, but I do just mean co-located ferrous and non-ferrous…not necessarily two targets that are too close together for the machine to truly separate into individual targets. And maybe that’s the answer…my air test example above doesn’t represent true separation, because the machine was just seeing one target with confusing ferrous and non-ferrous qualities. Essentially a trashy single target. Just like a deep, large nail vs the surrounding soil matrix! Of course, in the field that’s going to be junk 99.9% of the time…might get purely lucky that one time in a thousand and get silver. Just tried those same two test targets in an air test, and pushed them a little further apart, and bumped the RS to 5: Again, just an air test, so I’m skeptical if this will hold true in the field, but the gap between the ferrous and non-ferrous is consistent and noticeable…much more indicative of two distinct targets. Perhaps this is a “tell” for in the field as well? If there’s no prolonged gap after circling, walk away? I’m probably just trying to read too much into the 2D trace again! 😄

That's what I did 7 years ago! You will love the machine, great decision. Wish it was around when I started to pump the brakes. 👍

I was hoping to find both on the same day. But the morels weren't popping up yet. So the same week will have to do.

This is the old girl! And our 2 sons and daughter with their spouses and our grandchildren. Our youngest grandchild, Oliver was not born at that time. But here is Oliver helping Grandpa a couple of weeks ago celebrating my 75th birthday.

As for the terra, I think they are not up to par, and they will be worse on heavy soils.

Thank you all for your experience and advice. i am also inclined to nocta. today i called a colleague who is professionally engaged in devices in Ukraine. he sells them and tests them immediately. he said that nocta score 2 would be an ideal option for my soil. it is a little bit of a cut down legend but for me i think it is enough. In Germany, many people have switched to Nocta. I was a little skeptical of the Turkish manufacturer, but now I am sure that I will buy this device. first of all, it is the price-quality and 3-year warranty and positive reviews.

I suppose you could use fibreglass. It would be a simple task to make a mould using the lathe. It would be interesting to see how a skid plate would wear over time with glass fibres being exposed as the resin wears away. The resin itself is a bit brittle and may chip in use. Not sure on that one to be honest. I do know that I hate working with the stuff.

No it's legit. Everything I talk her into doing, seems to go awry. However we have gone to Minelab Partner conferences, once in England and once in Sardinia, and she really enjoyed those trips. She loves to sight see. I'd go to the talks and she would sit around and read and relax.

I hope I am not confusing you more, but I suppose it is worth considering another course of action. I don't know how high your threshold is for a ferrous tone that repeats often, but with smaller ferrous limits under and above the 2D line first and an audio ferrous tone on pitch1, surely a "dirty" signal is much better distinguished from a non-ferrous, clear one. Also about tones, I'm talking about using depth audio themes instead of single bins. All metal and red numbers do a great job without dumbing down the instrument and still the screen indicates potential iron. Also, the volume of iron equal to nonferrous enhances a signal worth digging much more. By raising the sensitivity beyond 23 points, I have noticed that instead it is better to increase the separation rate to 6 in some cases. Be prepared to listen to a very frequent ferrous grunt, but then tell me what happens in the same context....

VERY nice! I used to tent camp with my parents when I was a youngster at Ft. Desoto campground down here in St. Pete. Now days, your rig is more my style. 😄

Aye one thing you can sure of your missing gold, Irish Pat says, "never leave a patch til ya dug another piece"

Yeah did same with clipped on Z speaker but unfortunately didn`t have Z on and walked in about another 6ks before I realised, spent day helping son dig up some weight, fortunately GPS was on and backtracked on way back to camp in arvo, was on ground underneath a low tree branch we had to snick under.

Thanks for the insight, Dave - lots of good food for thought here! I hadn’t considered the recovery speed being a factor. I chose 4 because that’s been my basic starting point on the Equinox. On that machine, it usually was the best combination of excellent depth while remaining fast enough to not notice any real decline in separation. Target IDs didn’t seem affected at that level, but of course the Equinox had a much more compressed VDI. Anyway, at sites with more significant target saturation and/or contamination, I’d bump it up a bit, but it was fairly rare - I would generally tend to opt for a smaller coil before going any higher than 5 or 6 on the EQ800. But it looks like it might be worth experimenting a with little higher recovery speed on the MC. For audio, I’m using a slightly modified 5-regions All Tones. The most noticeable modification is the tone breaks - I have it divided into sub-nickel, nickel, trashy, IHP to dime, and quarter & up ranges. Less obvious is the flat tone range for nickels - I didn’t want a tone slope there because it was making nickels sound too iffy or less attention grabbing for my ears: My sites so far have been public parks, but they each have a history of prior use that lends themselves to heavier than normal iron nail contamination. I’ll definitely try ATLC again - with my increasing knowledge of the machine, maybe I’ll find the iron falsing tendency will be less noticeable when I give it another try, especially when coupled with a different recovery speed. Yes, my area seems to be better suited for higher sensitivities - mineralization is generally very low, and the MC does a fantastic job of killing EMI. I get pretty tight VDI numbers at sensitivities between 20-23 on non-ferrous targets uncontested by iron. VDI definitely seems to suffer as I get above 25. As I mentioned, I usually have to raise the sensitivity to bring out the iron range on many of these falsing signals. Lowering the sensitivity makes me concerned I would just get genuinely fooled more by tight non-ferrous tones and traces with no hint of iron. On the flip side, perhaps if I lower sensitivity into the teens instead, the falsing high tone iron goes away, but a coin/relic at a similar depth would still show up? I don’t have enough experience with the Manticore and deep coin/relic targets to answer that, yet. I agree, tuning for stability is key, and you get what you get on depth as a result. Up to now, I always just thought of stability in terms of EMI or lighting up too much micro iron at old home sites - excessive chatter meant I needed to back off sensitivity. The Manticore runs very quiet for me at 20-23 in most cases - I just have the constant occurrence of too many large nails masquerading as co-located non-ferrous targets. I suppose now I need to consider big iron/VDI stability, as well, and I need to drop sensitivity more than I think? Lots to consider and experiment with!

Didn't you get insurance money out of the six detectors that was lost in the fire (so you could buy one from Gary)?----Sorry to hear about the fire.

I think due to the nature of the problem, Minelab would be kind enough to resolve this one even outside of warranty, while not officially a recall it is very similar. They're very good with their warranty, and this is one I think they'd accept outside of that.

Just making a comment , I wish , do not have a PI anymore . Need to come across enough findings gold , silver ] to add to my toys / tools 😉 But thanks for being here / there
