Sweep arc.

[Samuel_Champlain_FTW]

What sort of sweep arc is recommended when in multi tone conduct/two tone ferrous ? Can you go long with the conduct (near 180 degrees)? Should I stay short on the TTF sweeps? Should I always keep things compact and slow?

I'm curious as to how you experienced users hunt.

In TTF or TTC you are simply listening for the high tone and then checking the TID to determine target type. Same in multi-tone with the additions of the mod-high tone.In either case the swing speed needs to be purposefully slow. When the threshold nulls (around iron) go back over it to check for masked non-ferrous targets. To unmask you need to attack the target from different angles looking for a high tone - if you are in open QuickMask check the cursor position.

You can't go at 'normal' sweep speeds to do proper interrogation. Go med-slow and then real-slow (circling) around possible targets (those quick high chirps). It only takes a few seconds with the E-trac to determine the probable target ID.

Ok, thanks for the tips!

sweep speed depends on iron targets per swing. If your at a site where your getting 10-12 iron hits per swing.....you need to go turtle slow. Like 5-6 seconds per swing. It feels incredibly slow, and don't fool yourself and speed up, it is easy to do. Actually count, one thousand one, one thousand two...etc.

now if irons hits are more spread out you can go a bit faster, but in TTF slow and low wins the game!

Ok, goes4ever. Sounds good, my man.

I was at the junkiest beach of all time today. Full of nails. (Supposedly they pulled a house down to the beach and they burned it back in the day)

You'd walk over large nail infested areas where the detector would just null for many steps. Large arc, or small arc... when I swung fast... I ran into problems.

Using a larger arc and going slow, was just as stable as a smaller arc. The only problem I had was the strain it would put on my shoulder/wrist after a while, when going slow... using the large arc. Perhaps I should work out more, and complain less.

As junky as it was, I managed to find a ring and a silver dime with the TTF and going ultra slow, . The ring came up though the null at 9-42/9-43, if I remember correctly. It's a trench art ring from WWI or II. I'll post it shortly in the Etrac forum,.
