On the S-bent stock shaft the lower rod only slides up so far before it dead ends. If a person gets an upper straight shaft(costs extra for the non-metallic carbon fiber one) like those available from Anderson detector shafts, the lower rod will slide up further to make the X-Terra more compact. The same goes for my Musky with the upper straight shaft, the lower rod slides about all the way up.
I wish Minelab made a hard shelled case with a foam interior for the X-Terra's. My Garrett 2500 had a nylon type soft case with foam interior from the factory.
Also for a grab and run detector set-up, keeping the detector all in one piece for quick access. The detector & coil can be strapped or put on on top of alot of deep foam(about 3" to 4" or more) and/or a vehicle seat is also soft. I put mine on the back car seat with the control box on an extra piece of foam all covered by a darker colored(like a shade of brown-beige and not bright white) bed sheet(poly-cotton blend is best). It keeps it out of prying eyes(sight) and also shaded from the sun. A soft place in the trunk(completely out of sight from theft) is also a good idea. Maybe line your car trunk with deep foam.
The best cases at Pelican for a metal detectors are models 1700, 1720, 1730, and 1750...get olive green or beige but not black because of the direct sunlight...you will be very please with these waterproof cases...

Someone told me to use a bow case, also maybe a gun case but these are usually too thin and a person needs a thicker one.
A person can also make his own long sized metal detector case at home if you are handy, out of about 3/8" to 1/2" plywood, piano hinges, and with foam. (A person could get foam from a bedding shop, buy foam used for under sleeping bags, or the 'waffled' foam used for putting over a bed mattress, then cut this to fit.)
Hope this helps.
P.S. I also forgot to mention an 'old suitcase' you have kicking around at home or get at a second-hand shop, 'either soft or hard sided' with deep foam you can put inside yourself, makes a good inexpensive metal detector case. You can cut out the shape of the detector in the foam with a box cutter knife if need be. A foam lined 'duffle bag' may not be good enough. I have a Texas Grapefruit box that is made of very strong-rigid cardboard. A person could make a detector case out of something like this(thick cardboard box, deep foam lined) by cutting, using a tape gun, and modifying this too.
