OK if you are like me, the Infinium stock shaft sucks. The arm rest wobbles you cant tighten those plastic nuts but so much and the worst of it what were they thinking with the S shaft? Does it hurt your wrist like it does mine?
I had to hip mount mine because of the # shaft and the poor weight balance. I wanted a straight shaft but after looking for one, I was not going to spend $150.00 with shipping for something that should have come with the detector to start with.
So I decided to make my own, First thing I wanted a grip that was secure and angled correct for my hand and providing a firm grip. I also wanted better weight balance for both coils. After a little trial and error I had to make the shaft 6" longer the the S shaft so with the stock large coil the box could be mounted on the rear for perfect balance. I wanted a quality shaft that used, as much of the stock parts as possible.
I used 6062T6 Aircraft Aluminum for the shaft made at the correct dimension to fit the stock connector to lower shaft.
I used a custom handgrip with foam padding; the grip is adjustable so you can move it forward and aft for you proper forearm length.
I used the stock detector box mount with holes in the front for 8" coil, and holes behind the arm cuff for the Stock coil.
I used the stock arm cuff and drilled 3 holes so it can be moved forward and aft, for my detector I drilled the cuff to use all 3 holes at once for no wobble.
I used all stainless steel 1/4 cap bolts washers and lock nuts and tossed the plastic crap.
You reuse the stock lower rod and I have no wobble issue with the 8" coil and a little flex might be a good idea when hitting rocks anyway to protect the coil.
As you can see in the pictures, you can balance detector with one finger on grip with either coil by moving the box. The difference from the stock shaft is much better, I can use the detector now without hip mounting it.
If you are interested in the shaft Oh and the model is mine. Reid [email protected]

Very stylish, and high speed. Smooth lines accentuated by graceful elegance.

Now then, the straight shaft... Have you tried a velcro strap on the open part of the cuff? I like mine (Anderson straight shaft) as I can let go of the grip to pick something out of my scoop, while still retaining control of the detector.

You have constructed a very nice product. Something to be proud of.
 

awesome job!!!!

nice professional Job Reidman. looks like it will do the trick, and probably a lot cheaper than my Anderson! does it come with the model....or is that an option??? :tongue3: nice job bud. you should be proud!!
 

Nice looking Infinium shaft there!!! :icon_thumleft:

The handle is nicer than the one on my Anderson!

The only thing I would add is a quick release velcro strap on the top cuff so you could let go of the detector and use both hands like on the Anderson.

Very professional looking construction (I'm sure you could sell a bunch of those too)!!! :wink:
 

Well I have a velcro strap didn't install it because the balance is so good and I bend the arm cuff in to fit my arm it just isn't needed.
 

Another option I did to mine was putting a ring on the side of the shaft, I clip it to my pouch with a carabiner when I am in the surf so both hands are free to dig, another reason I don't use a strap easier to let go of the detector for digging.
 

Will have 8 of these at DIV then whats left can be had on Ebay. Reid
 

Are you still making these and would it work for the Sea Hunter?
