I dont understand why excal still use the old bbs coil though or do they use the newer tornado these days? Also I belive explorers/etrac are deeper because of the pro coil.. Stick an aftermarket coil on a sov (S12/SEF 10x12 etc) and you will blow anything away and be on the heels of a PI... On the beach NOTHING will touch them imo..
I'm pretty sure Excals come with 8 or 10" Tornado coils these days. Somebody once said to me that the "Excal" coils are weighted. No they aren't, I said, they are just heavy because they are BBS coils. Anybody care to correct me on this? I know the 10" Tornado on my GT doesn't "float" in the water, and I'd hate to use that old BBS version of that coil. It's as heavy as the WOT!
I've said the very same thing about the Pro Coil in the "Compare The Competition" thread. If the SE and Etrac were all that much deeper than older Explorer models then what gives with the new coil? They could have saved a bundle by just throwing the already mass produced 10" coil on those models as well. And we all know that Minelab isn't exactly fast serious about adding new versions of hardware to machines just for the fun of it. After all, if that was the case they wouldn't be still putting a boat anchor (shaft) on the current GT models.
That's why I'd really like to see some head to head comparisons on a GT with 12x10 coil versus an Etrac or Explorer with the 11" Pro Coil, as well as a 12x10 on those units as well. Based on what I've heard, read, saw, and used (my Explorers), my money is on the GT at least in my ground. What I'd also like to see is separation comparisons of these machines with the GT using a 12x10 and the Explorer/Etrac using the Pro Coil. Even the 15x12 on the GT would probably shock the heck out of people in it's left/right separation ability. It's not that the stock 10" coil on the GT isn't awesome, it's that these SEF coils are even better. Blows my mind how they can feel like an 8 or 9" coil.
While on the subject, I'm not even convinced that FBS technology (more/higher frequencies) has any benefit over BBS. In my soil my Explorers got less depth than my GT, had more trouble with RF noise or ground mineral instability, and didn't run nearly as smooth. When you've got more than high enough frequencies to hit hardest on gold and other low conductivity targets I don't see the point in going even higher with FBS, and BBS has all the good ones in between and down to the lowest to penetrate rough ground and hit hardest on silver/copper. In my view more isn't always better. Now you've got issues of more channels for RF to play havoc with, or specific frequencies that might reflect or chatter of certain ground matrix's/minerals. That was true for me in comparisons of FBS to BBS at some of my sites, and you can chalk it up to whatever reason to blame it on. I just know my GT gets deeper, runs smoother, and it's as finicky about things when cruising over rough ground.
