Sniffer xr 71

[Ribeirinho68]

good afternoon,
Does anyone use the sniffer xr 71?
I'm in trouble, I need help.
I purshase a sniffer and when approaching near the ground begins to whistle, and it is impossible to detect, has anyone already had this problem?

thank you

have the manual, already tried several adjustments, .. with the coil stop it goes well, with the coil moving and approaching the ground it goes crazy
