I strongly agree with vferrari about the unenclosed top of the coil being a non issue for land hunting use. And just to let you know, I'm still interested in obtaining those solid covers for all the Minelab factory coils for the Equinox 800. Do you have the factory 15" x 12" coil? Is the aftermarket round Coiltek 15" DD a big improvement over the 15" x 12" factory coil? Price difference if any?
I have both the Minelab 12 X 15 and the Coiltek 15" round. In the short time I've had the Coiltek, I find it's slightly deeper.....maybe an inch or two, but, a bit heavier too. It makes the Equinox nose heavy enough to where I would use a sling for any hunt lasting longer than a couple of hours. It doesn't pin point quite as easily as the 12 X 15 either, which is no surprise, but, it's not that big a deal. IIRC. the price difference was about $20-30? If I was only going to get one of the two, and the added depth wasn't important, I'd get the 12 X 15. I can swing it all day and the quicker pin pointing is worth it to me.
