Been a long time F75 user, now have a Deus also. I am VERY new to the Deus. My honest opinion at this point is they are very similar detectors, and in most situations one eill find what the other will find. The F75 delivers the goods at a lower price, the Deus offers extra features for more money. I find the F75 to be a bit more grab and go, just pop in batteries if need be and I am ready, no charging issues, etc. Coils are cheap. Deus by all accounts has an edge in the thick iron (have not seen it yet myself), and the extreme light weight is appealing. I am glad I do not have to choose between them. Maybe a year from now one will convince me I can let the other go but it really is that kind of a close call. In the end it will be a very personal thing for each user as both are excellent detectors.
