thanx for the input. I ran out and bought a 705 when I saw the "hat trick" that my friend's 305 was performing. This particular site (a traveller stop adobe site in CA) has given up about 10 reales, various early seateds, many 1810 to 1840s buttons, etc... As time went on, the site got cleaned out. And now, the only place left that has anything left, is a particular area that was always filled with iron of all different shapes and sized. I mean, so much that it's a continual blanket.
I've been through it with 77b's, 77b auto-legend, Silver sabre, shadow x2, and all the "regular normal" machines like CZ's, XLT's, 6000d's, Explorers, etc..... And then one time I took this friend of mine out there with a 305 w/6" HF. He was spanking a blisstool, a CTX with small coil, and an explorer with a FIVE TO ONE margin. A few times he'd show us signals that, I had to admit, I wouldn't have heard on my own.
So I ran out and bought a 705 with 6" HF.
So do you think a 305 is somehow different than the 705 in this regard ? It shouldn't be. Hmmm.....
