I currently have 3 WOT coils, I have one spliced on one of my Excals, and the other Excal has a Sunray S-12 Intruder coil that just arrived this afternoon, I will splice it on too. I have one on my custom waterproofed Sovereign GT and I had one more for my land Sovereign GT. I cracked the coil on the waterproofed Sov GT so I am taking it off and replacing it with the one from my land Sov.
WOT coils are 15 inches wide DD coils Vs the stock 10 inch DD coil, all 3 of my WOTs are hot coils, they sound off on metal before the coil is over it if the target is not buried real deep. You can cover 50% more ground with each sweep, and they are deeper then the stock coil. I want hunt with the stock 10 inch coil any more, just too small once you use a WOT.
WOT coils are made by Coiltec, which use to make all of Minelabs coils before Minelab started making them in house, and they are made in Australia......
Orange coil on right is WOT coil on my Excal, Yellow coil in middle is WOT that was painted yellow to stand out under water on my custom waterproofed Sovereign GT. Just to left of yellow WOT is the stock Excal with the 10 inch coil, that I will be changing the coil out and splicing on the SunRay S-12 coil on this weekend... Note the size difference of the footprint... On the far left side is my land Sovereign GT with the SEF 15" x 18" Butterfly coil on it. I have a spare WOT for it not in picture.....
