These are probably questions for Carl, but let's give it a go. Not so much questions as statements needing a thumbs up or down.
It is my understanding that 10-12 kHz is probably the best overall frequency for a mono frequency detector. Multi-Frequency SMF/Multi-IQ/etc., works great for hunting high & low conductors, but when a particular target/metal is sought, then a mono frequency to fit the need is best. I think FCC put a cap on the transmitted power back in the 70s, and pretty much all metal detectors since have been maxed to this cap as far as transmitting power. Frequency is used to get the best results regulated by conditions and target conductivity.
With 10-12 kHz being a good all-purpose frequency, a lower frequency, say 2.5 kHz will have better ground penetration but is more prone to iron falsing. On the other hand, a higher frequency, say 40 kHz will be more sensitive to small low conductive targets but has less depth or ground penetration.
Does this sound right?
