Had some luck with the Minelab Equinox and Cuda last week. The Equinox is a great edge cherry picker–gets right in amongst the caps and pins. Trick is to recognise the junk first–especially those “cap patterns.” Cuda is a great workhorse deeper than any VLF.
A tip I would give is to always look for the deepest water closest to shore. The same gully can have nothing if it’s ten feet further out but in close it can have good marl access. Track along to find this type of ground–this has worked for me many times. Biggest ring is (all 10K) 6.6 grams, and a no-date George the 4th quarter down so deep it sounded like a pin with the Cuda.
