Here is the answer to the coil bouyancy problem. It's called a "Ballast Ring" and can be made for less than $5 with material from any hardware or home improvement store. The prototype worked well in rough surf. Please post your fileld test reports. If you have any questions please don't hesitate to P.M. me. Thanks.

Hi craig good idea mate , i think some beach sand would do as well .terry in oz

Great idea to use freshwater which is denser than salt water to achieve the extra ballast, no metal parts, PERFECT!!

Thanks Mate,

Is this extra load heavy enough to keep it substantially down I wonder?

To fill with sand? And to attach/remove with velcro upon necessity?

On dry sand extra weight is not needed.

Preliminary tests showed that it added just enough weight to keep the coil under but not too heavy to swing in the wet sand. They advertise the coil as near neutral boyancy. This just gives it that extra little weight to keep it under. Please feel free to try it and post your results.
