Fix your floating coil problem forever

[Tony]

I have been reading about the floating coil problems for some of the White's UW detectors.

This can be solved by using a rubber discus as a weight.

They come in different sizes and weights and are perfectly streamlined (designed to fly through the air) for in water use.

Holes or slots can be drilled. The discus can be cut to shape if needed to fit around the bottom shaft or to keep it perfectly centred and balanced. Velcro straps would keep it in place for easy removal.

The discus's can be had around for around $7 from sport shops or "you know where".

I would like just a bit more weight to my BHID 300 coil. I envisage a discus weight of 350g to 500g enough.

I will keep you posted on how things go.

Interesting idea. I would want to see thier bouyancy in water first. Just because it weighs 500g on land, doesn't mean its going to weigh 5g underwater.

Good job on thinking outside the box!

Jason,

Good point you raise.

Solid rubber falls into a density or specific gravity up to 1.5 (with water being 1.0)....so I'm hopeful.

I have a $7 discus coming my way....if it floats then I'll hurl it over the fence like a true Olympian.

I started hunting back in the late 70s,I used a whites coinmaster hipmount and pulled the control box around on an innertube. all the coils available would float, All I did was take an old sock with me and when I got to the beach fill it with sand and tie it on top of the coil. Try it, yo'ull like it.

Just a note all the weight will be in front of the coil, pulling the front edge down as it will be unbalanced.
This is another issue.
Wouldn't be an issue if the coil stem was mounted in the very center of the coil.

See my post how I solved my floating coil problem:

I can say I'm 100% satisfied with my mod on my PI.

Thanks Sven for the great post.

I will mount the discus so that it is "middled" on the coil.

I will cut a slot so that it fits around the lower stem and so should be balanced evenly.

One would think that a company as big as White's could design a good water coil that DID NOT FLOAT!
What were they thinking with a floating coil on a water detector ... or were they?

I thought they got the message when they came out with their 300 coil and put them on the BHID ... nope .. it floats too!

The detector came with two options
There are currently two versions of the Surfmaster P.1. available with the only difference being in the search coil that comes with the unit. For those treasure hunters that plan on spending most of their time on dry land, the non-weighted 9.5-inch coil is recommended. While it does have a tendency to float when submerged, it is lighter in weight and more suited for extended searching on the beach. The weighted 9.5-inch coil is de
