My question is for anyone. With the aftermarket coils that are currently in production for the Sovereign series, how do we know which coil has the best search field. I have seen pictures where it is depicted that the 10" tornado coil gets about a foot but comes to a V at that depth. I've seen pictures were the WOT DOES the same thing. I've also seen pictures that shows the 10x12 sef coil looses a bit of depth but the search field is solid straight down not coming to a V like the tornado...but what about Sun Rays S-12? What pattern and depth does it produce? I know its lighter than any of the previously mentioned coils at 25.5 oz w/cover but what about performance and search field?...Thanks Bombguy

here is a link to what I am talking about maybe this will help make sense of what I am seeing and trying to explain.

My understanding has always been that the concentric coils cone down to a point at max depth and that the DD coils are more like the chisel tip. The cc's are supposed to go a bit deeper but the DD's cover more ground at their max depth. The different of swinging the end of a nail over a target or swinging a broom over it.

So right Cudamark...the manufacturer's coils are a compromise between depth and coverage. After market coils pictures of they're field coverage are a marketing ply and that means lies and falsehoods.

Ok guys... so lets open this up to a broader discussion... Here is me setup: Soveriegn GT, 10" tornado, straight shaft. I have made an aftermarket product that keeps the sand off my unit when its Hip mounted.

Question, Is there a company that makes a "Lighter shaft assembly' for the GT? I am looking to cut weight as much a possible without loosing durability of my stock shaft. I have already unmounted the unit and am now using it in a "hip mounted" configuration. Basically, I am wanting to build the "Ultimate" waterproof machine kind of like having the Excal 2 but with Iron mask. I will never dive this set up...maybe only hip wading. I am already working on the enclosure box using cable clams PN1002, Plano waterproof box PN1460, 3m Adhesive sealant fast cure 5200 PN:06535, ( I still need to acquire a 1' coil extension 6 pin cable and a 1' right angle 1/4" stereo audio cable( any help locating these 2 items would be greatly appreciated)) after all parts are acquired then its a matter od assembly. I am using 1' cables so that I can make this box a stand alone unit... just unhook the 2 connectors and turn it from a water unit to a land unit or have a completely different setup say with another shaft and coil so all I have to do is add the blue box to the connection and I'm ready to go in a few minutes. thanks- Bombguy
