I've been out 3 times this week with my new coiltek Joey on the GT,So far I've noticed it it has very good depth,may be more sensitive to tiny objects than stock(lots of small bits of foil dug),pinpointing is an absolute dream,much less falsing on iron than the stock and is VERY MUCH less affected by EM interference than the stock,in fact I could detect in a field bordered by an electric fence without any of the crazy interference I was getting with the stock coil!,even my cell phone does not affect it!.As far as being better in Iron the jury is till out on that one.
Of course I will need a lot more time to see if it will replace my stock coil but it looks good so far.
