Hello everyone I am new to the forum in terms of posting but have been an active "lurker" for quite a while. Anyway I have been involved in the treasure hunting hobby since my son wanted to give it a try when he was in Boy Scouts. After 15 years of off & on hunting (depending on free time) we are both looking to upgrade from our current Whites machines. We are beach and park hunters in Southern CA, we have some tricky soil here which clearly the Equinox will prove much more effective for us than our current equipment. I have researched the main differences between the 600 & 800 but thought I would ask those who have had the 600 for a while now if they had any regrets in not getting the 800? If so can you describe why you feel that way and what features you feel make paying the extra $$$ for the 800 worth it. Thanks to everyone on this forum, I have not only learned a lot from you all but have had some good laughs as well with all the anticipation and second guessers exchanging wit while waiting for the Equinox to arrive.
