want to make metal d with greatest depths

[M.T]

hi everybody

i want to make metal detector can detect iron (size about 1m*1m) on depth 2 or 3 meter (greatest depths)
plzzz can someone help

my best regards

M.T, I think your machine shoud look like CEIA MIL-D1/DS.
For your purpose, the most suitable circuit diagram and loop configuration are these of TM-808. However you should increase distance between loops and dimensions of each loop. The original configuration of TM-808 has small dimensions and the operator can not make fine adjustment of induction balance. Note that MIL-D1/DS has adjustable induction balance.

Hi mikebg

i'm novices i think it's so hard to build it

i fount in this site sniffer 7xr1 can this metal detector detect a big size metal (iron) on 3m or more

M.T,
the loop system is more important than the circuit diagram. For greatest depths, you need an almost orthogonal coil configuration. It is more easy for a novice to buy an old metal detector and to modify its loop system.

Hi everybody

KT315 HHH i don't have engouth money to pruche Bulldozer

i want to find object like this exectly



on this barrel i think 1m or 2 of soil

plzzzz friend i help plzzzz

Rob a nearest bank!
Don't bother with poor metal detectors!

mean impossiple to find this barrel

mean impossiple to find this barrel

Let's be analytic for a moment:
* we are using metal detectors to find treasure,
* we are tending to find deepest metal detector, why?
* to dig more deep in searching for deeper treasure...
* so we are up to treasure..? right?
Than why bothering so?
Why not robbing a bank and get our treasure on most easiest way?
Who cares about detector anymore?

What are you expecting to find in the barrel?

hah Mr/ ivconic

mY treasure in a barrel.
i don't want to chok u about what in barrel

Yes, now we come to crucial question;
what is in barrel?
