Seeking a pulse plan suggestion

[jinbiao]

I would like to ask which project is the best depth and stable pulse metal detector. I want to make a high-depth machine with a 1 m * 1 m frame coil.
My goal is to be 1.5 meters to 2 meters underground, about 1 kilogram of ancient silver coins, please recommend a suitable pulse plan to me, thank you！

I like this pulse creation:

What is wrong with numbers of PI projects already posted on this forum?

The forum does have many excellent projects. I did DP / 71, but I did not reach the desired depth. I want to find a better solution. Sensitive to small objects 2 meters deep.
In addition, the pictures you send are not funny.
Thank you!

we need 3 meters of depth on gold mask 15x15cm with clear discrimination ferrous-gold.
by the way nobody told for what chinese did the pyramids ((( i think there are much gold in its inside.

China’s pyramid is protected by law, which is not my goal. The wealth inside cannot be estimated

Make a frame coil 2mx3m

The coil is too big and the small object is ignored.

Yes, there are physical-technical Limits

You can try to improve the signal evaluation

we need runabout accurate locator.

you can not change chinese law but you can change a law of physics?

I can choose a coil from 50 cm to 1 m, but I need to replace it with a better solution. I know silver coins are there, but I can't find them.

[kt315]

you can not seeking the silver coins because law of China is strongly forbidden and tresspasing of metal detecting.
forget your dream.
