http://www.findmall.com/read.php?25,829651,829651#msg-829651 Never use the one from whites Larry tested one.My ex coil is great it is the round one from kellyco .Took a little time to get use to pinpointing real stable sometimes so quite i do not think it is working i will run it over the buckle on my boot to make sure, depth is great.Also had to slightly drill my hole a little bigger for my bolt to fit through.Yes it met my expectation on weight depth target separation is great and it will pick up really small items 5 to 6 inches deep http://www.findmall.com/read.php?25,829651,830003#msg-830003 These items relic mode high tone.As for pinpointing i get get get it then i don't it kind of funny for me but never a real problem sometimes it is of to the side or front.Works good on beach here fresh water but haven't seen to many detector work good on this beach but my 6" ex and my 10"ex do better than anything else i have used .I would recommend it for my soil my area.I know everyone is probably at work now but there is a few people on this forum who have the ex and some have the whites don't know if there is a big difference i was told the whites was a ex coil just closer tolerance.Larry should know Rcasio44 has one and i believe Larry tested the whites coil.But my ex coils work better than any coils i have better than whites coils i have and the whites coils are no dogs either i just prefer the ex coils for me.Hope this helps some i thought you had most of these coils.
