carbon fibre. straight shaft coming

Hi Guys....

As you know NZ is pretty into boat building etc. I popped into a business that designs and makes carbon fibre booms and rods etc. Showed them the extendable shaft. They are making a straight shaft to replace the one with cams....will slide into the atx body and is tapered to slide over the last (thinest) part of the stock shaft.

You basically take the coil, and the lower garrett rod and slide it into the new one piece carbon fibre rod.

Should be easy to put back the original shaft if needed for travel. But won't really collapse (in order to save weight)

Will post pics once manufactured in a few weeks ;) should be much lighter, less water resistance etc!
 
Sounds great, but iny my opinion compact construction - is huge adventage. You can switch off your machine and put into your backpack in just few seconds.
 
Hi dmnz,

Your Preaching to the choir with a small diameter carbon fiber shaft for the ATX :)
Maybe when you get your new shaft installed, you could shoot off some photos to Garrett's "dumbbell" engineering department. Maybe then, they will quit making "free weights" in the future. Or at least offer a small diameter light weight shaft along with the current shaft.

You would think that Garrett, after making metal detectors for decades, receiving tons of feedback and suggestions over the years, could actually install their quality electronic components in a compact package using high tech low weight materials ... at least for their high end machine. And it's not just the materials used for the housing and shaft, it's the design. Do they even understand that a large diameter shaft with monster size silt & sand clogging cam locks actually has a lot of drag when swinging in the water. You add that to the weight of the machine and thickness of the coil, it doesn't take many no gold days to start feeling the reward isn't worth the effort in the water.

In part, they marketed the ATX for shallow water. It makes me wonder if they even have field testers or testing capabilities.

Is the carbon fiber shaft that is being made for you cheaper by the dozen? If so, put me down for one:)
 
I think it is costing 200nzd as it is a one off job. They mentioned the glass fibre shaft with the atx is very cheap to manufacture. The shaft I am making will be similar to that of the CTX3030. I guess once it is made they will be able to make others if you want one!

Can't wait as I love the machine and HATE the shaft and cams.

It is not really a thin diameter as I wanted the shaft to be able to use with all atx coils. Basically you slide out the lowest / smallest rod on the current atx coil and feed it into the new main shaft. It will be 1/2 to 1/3 as light as original with no cams to clean and lockup!
 
Very interested in seeing how it looks...if you would be so kind when it's done to shoot some good photos.
Thanks.

Hi dmnz,

Yeah, your new shaft may not be as small a diameter as you would like because your limited by the diameter of the lower shaft that is integrated to the coil. Then it sounds like you taper larger to the head unit.

I was going to purchase a carbon fiber tube as pictured below ($48.00 for 32mm diameter x 1200mm length, 1.5mm wall thickness), but then I realized that I would not gain much in the way as weight and water drag because of the integrated lower coil shaft. It's almost like you have to chop the whole shaft up, including the connection to the coil, and start over, or use an Infinium coil that has a regular attachment to a shaft. But at least you do not have to deal with those sand & silt clogging cam locks.

Look forward to seeing your end results
