I've been on many different types of beaches with my deus and never had a problem with chattering or falsing. It's a very good beach machine for dry and semi wet areas. In comparison to a decent wet beach areas type PI detector it's obviously not going to hold up in comparison for great depth. I use v2 so I can only speak from this experience. It gets great depth in the dry, good depth in the damp sand, but when moving to areas where the sand/pebbles area just dug floods with water, then about 5inches depth on an old penny sized target is going to be about it. Obviously you will get more or less depth depending on the size of your target. I've dug out a grill from a barbeque before which was much, much deeper. Took forever. Anyway...
My 'dry' (loose sand, doesn't stick to you when held in hand) beach settings are:
11.8khz
Disc 32 (pitch sound mode works great for items that aren't deep, but 3 tones+ is better for depth)
Sensitivity set at anything in the 70-85 range depending on conditions (tx power 2)
iron volume 0 (you can still work out iron stuff under the coil without it being set here)
reactivity 2 (silencer 3)
audio response 5 (audio overload 1)
ground balance on tracking
GB beach = no
'Wet' (water filling the hole) beach settings:
17.8khz
disc 27 (i use 3 tone mode with custom levels for this) target ID is not reliable so rely on your ears
sensitivity anything from about 50-85 depending on conditions (tx power 1)
iron 0
reactivity 3-5 depending on conditions (silencer -1)
audio response (1-5 depending on conditions, the higher the value the more unstable) (audio overload 1)
ground balance on manual (changing this to suit your beach)
GB beach = yes
I change settings depending on how far away from the water's edge I am, so a combination of these settings may be used.
If your machine is chattering away you have it set up incorrectly and it's not the machine's fault unless you have a crack in the coil, which is very unlikely unless you smash it against rocks regularly.
Add in a lot of practice and it's all good.
If you want better depth, you need a dedicated machine for the wet (or if you can afford it, something like a 3030 which seems to be a good all rounder). I'd suggest looking at getting a GT or any Sovereign as they're cheaper.
