coil help!!!!

In the 1980's I was faced with this dilemma while using Garrett's XL500 PI machine with its large coil.
I dreamed up this solution and have used it ever since.
There is a slight drag increase, but the 1/2" PVC copper tube size pipe (available in many hardware stores etc.) is small enough in diameter to cause very little trouble and it is quite strong as a brace. (I lean on my coil a little to steady myself when digging.)
This is my Dual Field as I use it.

The PVC is cut on an angle that allows it to be secured to the coil and shaft using electrical ties through holes drilled near the end and then taped with plastic electrical tape for a very strong attachment.

I created this angle brace to do away with the pipe and used it for a while until I broke one of the coil ears one day by leaning against it at a bit of an angle.
You can see how I used Shoe Goop and a strong electrical plastic tie strap to brace it and it has been a successful repair.
The PVC pipe brace was added as insurance and the coil has many hours of hunting on it now with no further problems.
Good Luck and happy hunting,
CJ

I never have a problem with the front of the coil kicking up, the problem was keeping the proper adjustment when I laid it down. This works great in and out of the water and it's easy to do, the adjustments are infinate, no drag in the water and it's not expensive. Also it does not weaken the plastic isolator like someone might think.

Thanks everybody for all the great advice. It js greatly appreciated.
The Minlab detectors have enough beef where the screw is to allow this great mod, but none of the White's or Garrett's machine's rod ends are that substantial.
Placeing a hole in one of those rod ends will risk breakage.
The small diameter PVC tubing doesn't create enough drag to cause problems and helps by keeping my swing at a slow, even pace that doesn't miss much.
As I mentioned I started using this method in the early '80s and have hundreds (thousands?) of hours of water hunting to draw on.
At over 200lbs I haven't had any reservations or problems using my braced coil rod to carefully lean on for stability as I dig with my huge scoop.
As mentioned above, the only time I had a problem was when I used an angle bracket without the PVC tube brace.
That resulted in a broken ear on my coil.
Broken coil ears happen from time to time and are less likely to occur if the PVC tube is used.
Respectfully submitted for your consideration,
CJ
