Same spot, different detector

You are getting some pretty good relics lately, love the snake buckle!

Great stuff mate.
Large high conductors I'd be trying the 2 tone mode on the Kruzer with 5 kHz. Listen to the faint zip zips, as there won't be much tone modulation on the real deep ones.
Or if the ground isn't too mineralised, 4 tone is the go.

Thanks Nenad, the site is pretty trashy, so I have tried a lot of options with the Kruzer and Simplex. The 8 concentric on the Kruzer is my favourite for this site, but yet to try your suggestions.... next visit :Y:
