From Miners Den in Mitcham. There is a waiting list and you have to pre order. I waited about a month for the other to be filled. Well worth the wait. I will put up some videos soon using this detector. When my mate and I rented one we both found gold very quickly. Hence the purchase. Very impressive.
Sorry for the very late response. I have found some good gold considering the lock down situation. Definately the best detector. I have recently bought the Nugget Finder 12" coil and it's dynamite.
Oh the charging question. The battery on the 7000 takes around 4 hours to charge which is about the same as the 4500. It does depends on the charge pack you use. It needs to be at least 2 amps output to get the 4 hours though.
Haha yes. Sorry for the late response. Really enjoy using this machine. Although I've been limited getting out I've done alright. I will be doing some videos starring September.
