Gav, putting this in here as it’s pretty niche, in lost 'n found forum it may not be seen by desired audience.
Left field, I have someone who is seriously considering flying me down from Bay of Islands (!) to detect for a lost necklace under a wharf near Chch.
Wondering if there are any prospectors in the area who have Scuba-Detecting capability?
Depth 4-5m and an expected 3x5m corridor (was a straight drop off the wharf)
Please message me your contact details and I can put you through.
(I don’t really want to fly the length of the country for this if I can avoid it)
