AT Pro mounted on new Mars shaft

I recently purchased a Mars Shaft for my Sorex Pro detector. For those of you who are not familiar with the Mars shaft, it is a pretty well done copy of the Deus style shaft the folds into a small compact package. many like this style when traveling as it can be stored in a carry on bag.
I liked the shaft so much I decided that I was going buy another along with a AT Pro and do the conversion.
I purchased a brand new AT Pro from Jeff at Quality Detectors and got it fast. I ordered the Mars shaft from Serious Detecting eBay store For $120.



Now a lot of guys probably wont like the fact that I took a brand new unit right out of the box and hacked it up BUT the final product is worth it in my book.
I needed to cut the 2 mounting post on the underside of the AT Pro, (you know, those post that snap off and leave your control box hanging by the cord) You will need to follow the measurements given when making these cuts. I opted to cut mine just a tad shorter to get the mount closer to the control box. I had to also trim the small support webs along the side of the mounting post.
Now this is the important part, MEASRE THE SCREWS YOU USE TO ASSURE THEY ARE NOT TOO LONG AND PUNCTURE INTO THE CONTROL BOX HOUSING!



Now that the mount is attached to the AT Pro control box it is only a matter of sliding it onto the shaft assembly. It has a "Dovetail style rail that it mounts on.




Now I got thinking about the original shaft assembly, it would be nice to be able to unsnap my control box from the Mars shaft with one coil and transfer it to the original shaft set up with another coil, so I got to work.
I fashioned a tapered "Wedge" like was on the Mars shaft out of a piece of 1/8inch aluminum I had using a jig saw, file and a drill press. I fashioned the male dovetail with a file to match the female receptacle. I then drilled the upper shaft to mount the wedge. I had to do some measuring so that the control box final mounted would be in the original position and all controls could be easily reached with the users thumb.
I must say it turned out nicely and is a good solid mount. I can now switch the complete control box over from one coil/shaft combo to another in under one minute and that includes attaching the coil cable!

I really like the final results. The Mars shaft is well made and even a bit sturdier than tits Deus counterpart. It also comes with a ton of different washers as well as the rubber cushions that tension the rod locks. (Take note Deus!)

How does the weight compare?

It is a tad heavier but is much more robust. I think it would hold up great in water hunting where the stock shaft assembly tends to flex a bit.

Not buying another detector until someone makes a dedicated park gold detector with 100 points in the gold range, sick of the same old same old, I need something to met my detecting needs and NO one makes what I need.
anyone can find silver its a sitting duck I have more than enough of those duck hunters, so my pocket book stays closed until someone see's the future of detecting.

if you are out there I can let you know what I need..

More coils than any sane person would need.

Machines are not in order of preference !! I can't read big blocks of writing , so the enter key is a good tool.

I share my experience of my detecting both the good and not so good both on and off the field, not here to keep everyone happy, just share my experience! if it helps someone that's great, if not that's great too--- so take what you need and leave the rest !
