I probably should have said a bit more about why I have decided to keep the F 75 and not the Deus.
As a gold nugget detector, the F-75 does way better on tiny targets, even when the Deus is used in it's Prospecting mode.
For general detecting main problem with the Deus is that deep iron (for me) is not distinguishable from deep non-ferrous, it all sounds the same. Perhaps it's a lack of discipline or attention on my part. With My F-75 in Boost Mode, I can usually get a bit of high tone and often a recurring ID (if jumpy) on deep non ferrous.
Add to that that I Paid less than $500 for a cherry used F-75 LTD and my deus with 2 coils cost me $1500 used, it becomes clear which Imshould keep.
It's a nice machine and light as a feather - that part I will miss.
