I have pre ordered mine. I look forward to being able to hear through the headphones. It also allows me to have a spare pinpointer to share if someone borrows my detector. I believe this will be worth the $199 to me.
I haven't pulled the trigger yet it's hard for me to justify the money when I just got the AT pro last year the hf coil is cluttering my mind 14khz sounds pretty cool.
Having bad experience with my various previus pre-orders i will wait fall , first we dont know how good will be v4, if v4 have any flaw , and probably will have ,then u need to downgrade it to v3.2(i am still with v2) and u will be stuck with ordinary pinpoint until bug is fixed, only advantage at this point will be lack of interference with coil.Being distributor of some metal detectors i still have approximately 40pcs of other pinpoints on stock so patience is virtue when it comes to purchasing new electronic products .
