much junk you still are keeping of

your laught is not to that place. you are going in a school?

- your Home Work is not done tommorow! go out from class room and do not back without your parents!!!!

Automax is selling production on price $139.

automax is a clone from German simple handy metal detector, I believe.

another model from Bosh

Hi,
I think you're probably right: I think too it's a clone of some old project, from a magazine.

I've built myself a couple of them, but not as good... they use ics but this small transistor one it better than those.

Also... today I found there's another Bosh made stud detector that's maybe better than the "skill" one... do you know it ?

It's rated 10cm on ferrous and 8cm on copper buried stuff, coin sized... not bad for such small coil there.

For Ivconic: do you know that model from bosh , DMF10 ???

Kind regards,
Max

[ivconic]

Yes DMF10, in local shops price is 125e. I tested it and compared with Skill.
Not better than Skill. Skill is noticeable better and costs only 75e...
However..i have hunch those are based on same machine inside; same controls,same processor... What is difference? Most probably some adjustments and coil!? Not sure. And of course brands; Bosch is always more expensive than Skill !!!

Look F2,F4 and F75...and compare with some Fisher models... same old story continues again and again...

I am sorry for hurting your feelings. But this gives you not the reason for getting impertinence.

here it is...

the crappy pinpointer !

All made of junk...

Kind regards,
Max

Wow! I missed that?
Your "crappy" pinpointer looks much better than you presented it!
You are modest Max. That is a very nice handmade! Congratulations!
Pretty handy and pretty nice.
Cheers!

I'm thinking seriously use it for to find in small streams this category of nuggets (in the pic small Peruvian silver nugget).

Hi Esteban,
I think it's good for these small things: I have a small gold nugget of about 3mm diameter and it detects that at 5-6mm if good tuned.

I think it will be very nice for nugget hunting where a big coil is sure unuseful on that small , elusive targets... expecially if the coil is DD: the pinpointing is difficault and the wide area coverage doesn't help locating the small nugget in the e.g. sand.

I think the circuit could be optimized and power increased a bit but maybe one will gain just few mm more on such small targets.

Anyway, for the scope it's intended, though so simple, I think is very good.

Kind regards,
Max

Hi,
thanks... I made using just trash... things recovered from old projects... old stuff apart a new 9V battery inside, all is made of old junk from here and there.

Then I painted it all-black... just to remind me it's something useful... not something to trash from bench!

I'm really interested in farther pinpointing too... must find some good schematic.

A friend that uses DP asked me to search for a good one... cause, you know, sometimes you dig large holes (say "wells") cause of that deep detection and recovering / pinpointing the target is not easy... often is on well's borders/walls and must dig laterally... waste of time... expecially when cannot pinpoint with a common md.

This happens sometimes also with normal MDs and single small items: on the walls... and often an easy pinpointer like this I made is not enough...

There a good pinpointer like the Skil will be really useful... but also some good schematic could be enough I think.

I will look for it... but if someone has some good idea... please post here.

Kind regards,
Max

Max, speaking of getting more depth out of a pinpointer, what would happen if a bigger coil could be made for one, say about 1" in diameter, would that cause any gain on depth? I have a Sherlock pinpointer, just wondering if a larger coil would help.

Hi Steve,
these that use the ferrite rods need ferrite to wind coil on... otherwise they work weak or don't work at all.

In PI kind, instead, a larger coil will be a real benefit and the gain in depth could be consistent, many cms I think.

I made other schematics based on Q-variance and can say that some are good for the use of larger air coils... like 5-6cm diameter... they could detect stuff easy at 12-13cm too, and don't require ferrite in these cases.

The problem is that some are really unstable circuits... you need constant retuning each time you switch them on... so are not so good.

I belive that a good , small PI would be really helpful in such situations... but so far, apart small SMD HH example by KT315, I didn't see any good schematic of those.

Kind regards,
Max

Hi Max

Good handmade pinpointer! As I told you I'm thinking seriously for to find gold nuggets... Yes, for the simplicity is good!
