I use it on occasion with success. It's not a trash hound ,,,,,with the etrac's ability to average targets you will get a lot of strange numbers using it in the trash with multiple targets under the coil. Go slow , try to pick up a target at a time , doing the "wiggle" can be tiring with the mass of the coil.
Your dirt will be the biggest factor on performance. Mine is very magnetic and auto +3 produces plenty of falsing. Higher sensitivities may be a hindrance. Just because it's 50% larger don't expect 50% more depth than the pro coil,,,,I think I might get a couple more inches which is acceptable as those could be very productive inches. Your dirt may produce different results.
The weight is another issue even though they are lighter than the SEFs. A "swingy thingy " may be in your future if you plan on using it for long durations. A terrific alternative and extremely cheap solution to the weight issue is a "Yuppie Puppy" no pull harness from WalMart or e-bay,,,,no kidding it works like a dream for 10 bucks. Put it on just like you would on your dog (except backwards

) and attach a 3/16" piece of bungie type rope (available at HD or Lowe's) to the ring where you would normally attach your leash and tie that to your detector and off you go with a little adjustment here and there to get it just right. http://www.ebay.com/itm/like/130954711888?lpid=82. I use a plastic "p-trap" o ring on the lower shaft to tie it to. You will also want to get a spare lower shaft as the coiling on the WOT is bit large to slip through the lower shaft easily and that makes it a PITA to install even with a string,,,that may have changed on the newer models.
