Hi John,
The BH phones will work fine with the T-IV and also have volume controls for
each ear, which helps a lot for those with hearing differences in their ears.
The BH phones are just 8 ohm types but that's really what BH units are
designed for anyway.
Actually, most all detector circuits are designed for 8 ohm phones, which
is why most detector companies don't emphasize more expensive phones
for their units. They know they aren't really that necessary.
The higher priced phones with greater ohms (75 to 150) are a bit more
sensitive to deeper & fainter signals, but the advantage is not normally
needed in most searches, plus the low cost BH phones are pretty sensitive on
most deeper beepers in my long experience with them. I really feel
that you'll be very satisfied with them. I really don't think you'll find any
better phones at WallyWorld either. Good luck in your hunts and keep
this forum apprised of your progress! The T-IV is a very capable unit and
I know you'll make some great finds!
Welcome to the hobby and Happy New Year!
