I have yet to experience a Vx3, and I think its a great machine.
Have just ordered a F75ltd from a dealer on TN. I understand that the F75 is a "hot box" from the factory.
By that I mean that the default factory setting push the detector to it's upper most limits straight off .
Getting every ounce of sensitivity out of it comes at a cost as I hear it has the effect of making the detector sound a bit "chatty" .
Some people really don't like "chatty" and cant work with it. ( As for me I have had chatty detectors before)
If you like a quite hunt with an F75 you have to dial it down a bit at the cost of depth.
In comparison my At Pro in factory default has it sensitivity set to 3 bars below maximum sensitivity.
Also if you are planning any beach work how bout a multi frequency machine..
Good luck,, with either I don't think you can go wrong, just what suits your style
