hesamavr,
               this pcb's 200% no errors.

and my powerful ugly dp.
this is my 1st dp double sided pcb, from eugene52. and it works fine w/out errors batt/low indicator omitted. i use irf 840 and same power output. this was tested in very harsh invironment to proved the reliability and stability of dp schematic i posted in actual usage in different kinds of soil including salt water, i test it in actual underground burried metals in 40cm search coil at 5ft it detects the metal cal 5.56mm ammo box.

in testing pi machine dont rely on air test, it is very different in actual ground burried test. and dont believe on pi discrimination function its not functional. unless, if separate metal location and same size metal in different kinds of metal and same deepness. it is impossible to discriminate mixed metal in same location/hole,eg big aluminum metal above the small gold.
