opinion metal depth

[Luc]

Hello,
I would want a opinion on as the metal work for depth tf900/tm808/cs9000.
Excused the English bad one.
Thanks.

Their work is based on deviation of transmitted EM field, in present of large metals.
But ground itself, makes serious deviation on the EM field. Ground balance system can help a little. You must carry such detector 50cm above ground, and lose sensitivity for middle metal subjects.
Any Pi detector with large coil, can beat them.
They are only good, for large pipes etc.

Thanks for the answer.
I had thought next to md about depth why me seemed useful in mountain with high grass, what that devout with coil great hard work to be left over, if I modify the tx of 808 with high tension increases depth? With pi constructed I have not never caught up advanced depths in earth to a bond vlf, is coil issue?
Thanks of aid.

In each detecting system, you will confront with ground disturbances, whose determine limitation of depth.
If you look a trend of new models, you will see efforts to avoid ground disturbances (multi frequency, DVT etc.). Those models manufacturers declaring like deep search.
With two box, you must find way to avoid ground problems. It is only way to get benefit from two box.
