I have great soil. Either no bar or 1 bar on my F75. The 75 beats the Nox. I'm not doing anything wrong. It's just not all that deep. Works well on the beach though looking for gold. It gets a little deeper in the wet sand.
Kajunman is almost right. It depends on the soil mineralization and the target you are looking for. My former F75 could not detect an 8" coin sized target in my bad dirt. Equinox will go 11" easily here and with accurate tone and number ID.
Here is a quote from Steve Herschbach who was one of the field and beta testers for the Equinox and he has written several Treasure Talk blogs on Minelab's website.
"Just an example of where multifrequency can still go. Right now you will hear it said that when a detector uses single frequency, all the power is focused on that one frequency, which can give slightly better results on that frequencies preferred target class over multifrequency. This is because multifrequency spreads the power out over the frequency range, with each frequency therefore running slight less than full power. It is the compromise of running all frequencies versus a single frequency. However, with that single frequency you are focused on a single class of targets, and will do less well on the other frequency ranges than the multifrequency unit."
"But it does not have to be that way. That is mostly a function of battery power and the desire to keep power use within tolerable ranges. With new high power battery technology, the next step will be multifrequency where each frequency is optimized and running at full power equivalent to what you get running at a single frequency only. I expect we will see this development in the relatively near future."
I want to emphasize again that Equinox is not the be all end all of multifrequency. In fact CTX has better target id resolution and excellent ferrous handling that is arguably better than the Equinox. From my perspective the Equinox is just a crude proof of concept for Multi-IQ, with more benefits still to come. It should be fairly obvious that everything Minelab knows about FBS and has learned so far about Multi-IQ will be going into the next generation CTX and Equinox models."
Look forward to using the Garrett Ace Apex too. In really bad dirt, saltwater and deep target ID accuracy, modern multi frequency is hard to beat.
