You should test it if there is any depth- and performance difference using 9v versus 12v.
Usually not, and if you have such shown AA batteries adapter u also can use 8x 1,2v NiMH or eneloop accus.
You even can work with some rechargeable 9v block battery so the detector is more lightweight to use
but it has to be of good quality and always have a fully charged reserve block as backup.

thank you lots AK48. i have pics of '505-0227' board signed and your one seems upward just cause your is '505-0194'.
probably your board is fully matched with the schematic attachedSurfmaster_PI_sch.pdf

[AK48]

hi ! you're right man , my board matched with your attached pic ,

[AK48]

hi! i've got à good question for good technicien , if my board is " 505-0194 " and the coil driver is a TIP32 , i want to upgrade it with the IRF9640 !!! can i do , what will be the result ? my SMPI will go deeper ? will i used the same coil ? the rest of the components seems the same , can you show me what componentes i must replace and show me the final board scheme , thank you .

simply replace tip32 by irf9340 and resistor 220 by 390.
Result is best gold sensivity.
