Securing Coil

[desmond]

Just wondering if anyone has found a way to secure The Beach Hunter ID Coil for under water detecting. Whites provided a plastic fiber glass type of thing but it snapped off the first day I used it. Even if I tighten the screws as much as possibe on the coil, still kind of flaps around, which makes it hard in the water to keep the coil secure on the bottom of the lake. Des In Buffalo

Figure out what angle it is you want it to stay. Get a piece of plastic, like 1/8 or so, from one of the major hardware stores that sells the plastice to be used for window replacements. Cut a strip about 12" long by 1.5 inches wide. Put that in a vice and run a hair dryer or heat gun on it until the plastic bends to the angle you want. Hold it there until it cools. Drill two holes near the edges on the upper angle and do the same with the bottom angle. Run a plastic wire tie through the holes and around the shaft of the detector and then do the same with the lower angle only attach it to the coil. The plastic is held in place by the wire ties and the angle between the shaft and the coil will stay whatever angle you bent the plastic. If it's too shallow or too steep, take it off the detecor, and reheat it and try again.
Also, you can probably get some plastic from a plastics supply house and they will provide information how to heat bend it. jim

Go to Great Lakes Plastics on Broadway, west of Union Rd.
In front of their store are all the scraps and cut offs, they sell by the pound-cheap
You'll be glad you stopped in there!

I have the same problem with my PI Pro, we don't have the weighted coil.
I am going to also make an epoxy sand weighted disc to attach to my coils top.
Just have to make sure I go to the garden center and buy some clean non mineralized white sand.
