Thank for all your feed back , Maybe a design flaw was a bit of a harsh statement as I totally agree it's a fantastic machine.
It's just me not wanting to take my machine apart for transportation (lazy? probably but I am fussy)
I agree buy removing the lower stem it reduces the overall size of the detector to be very compact but I defiantly want the bag to be able to close as over here in the UK it rains a lot and the detector isn't the only thing in the bag. wet sandwiches are not very tasty 🙂
I now know that the control box can be removed from the handle, so I am in the process of designing / fabricating a new shaft with foldable handle , without cutting up my original shaft.
I will post pictures when I complete it for you all to see.
