Hello bubba,
Here are several pictures, showing the Deus shaft setup. Please note the coil cable vecro tie wraps, these are important so the upper & lower shaft can collapse. Plus, the button position with its thin wire needs to be arranged so when the upper shaft is collasped the button with thin wire follows the upper shaft. Also, recently started using the hipstick. Added the bungie cord mounting bracket onto the shaft, so now need to loosen the plastic bracket bolts so the upper shaft will slide, just loosen a few turns not too much and retighten when opening up the shaft.
My main reasoning for the Deus shaft is not for weight purposes but for transporting the detector, much easier to carry onto a site or transfering from an automobile. I've even carried this setup in a backpack, with smaller coils of course.
Really like this setuo on the GPX, mainly for carrying purposes or transporting to site.
HH, Paul
