no ot has not
but if you are smart you can add a sercuit on it which can discriminate and modify the deepness of the target

Hi husoasil ,danny475
                 Delta Pulse as deeper it is mean it search a big target, no need
                 discrimination.
                 the projectS has discrimination less deep {10cm ~50cm MAX}.
BEST TIME
 J.

hello, line, all pcb, schematic, lcd were posted here in this forum just search,

about discrimination, in pi discrimination function is ineffective, and maybe it is very difficult to design the effective discrimination func in pi. i don't know in vlf or tr tx md. but in my actual test on discrimination it is impossible to discriminate metal. as i said in test in one hole with different kinds of metal (mixed) ex. big sheet of aluminum over 1kilo gold and under the gold is flat bar. it will detect only the aluminum sheet. try it.

regards, ram,

hello line, what happened to your xr71? what trouble you encountered? try to review the schematic and compare the pcb you used and the schematic and also the parts in schematic not parts list, using parts list to schematic it will confused you,   also don't wired up the mosfet first after assymbly of all parts, test it first for exact frequency transmitt,negative voltage in ic exact 10.6volts (frequency and square wave output) use oscilloscope> download the free oscilloscope software zeitnitz and the schematic of test probe, it will be very useful in xr71/dp projects to speed up trouble shooting.

regards, ram,
