MsDigger and I just ordered the X-Terra 705 from Nth Queensland Miners Den, George was pleasant and great to deal with.
Hoping for delivery Wednesday or Thursday, only $20 reg post and he is going to try squeeze in a plastic sand scoop

So I am all ears open to suggestions from other users as to hints and tips. Input on the different coils and opinions on where is best suited to each coil.
Have read the entire section here.
Curious to see how the DD coil goes on the wet sand as they are marketing it to the gold prospector and say it excels in high mineralised ground.
Picked the F4 because i thought with manual GB I could work the wet stuff, and that was a big no.
Plan on getting a dedicated sea machine for the coming summer but hope the 705 will cope better on the beach then the F4, i do live on the Gold Coast after all but only touched the beach a few times this year. The Bounty Hunter is better for the beach lol. As far as a Goldie vacuum i cant fault the F4 and happy to recommend it as a 1st unit.
Also eying of the WOT as I love swinging wide open places, and wonder what it would be like on the beach.
