I have been asked from overseas to conduct a survey pertaining to the use of detectors on west coast beaches and the results you experienced.
As you are all well aware… (put briefly)… the sands are iron based… of volcanic origin from Taranaki in particular with the Glenbrook Steel Mill processing these Titanomagnetic sands… of which the iron concentration is approx 58% along with titanium and other minerals.
This iron has played HAVOC with our detectors for years, so this survey is to ascertain to WHAT degree of success/failure we have had (past/present) detecting it. So …I am asking both the “old hands” and the newer detectorists to pitch in here. Details…if remembered…beach, unit used, depth, and any comments welcomed…I will start…
Port Waikato and Kariotahi Braches…
Tesoro Sand Shark…depth 1 inch at top of beach to 4 inches at low tide. Maybe 4 and half inches at the most in 35% black sand. (Guesstimate)
X Terra 705…standard coil…OVL showed on black sand, patchy results with very little depth at low low tide…maybe a few inches. (sinker retrieved)…a guesstimate black sand 5% and less.
XP Deus ver.4 …absolutely no go with uncontrollable chatter. Gave up rather than spend time mucking with settings and moved on.
Thankyou in advance to everyone!!!
Guess I should also ASK…WHAT would your realistic expectations be on black sand:scream: Mmmm…I would be happy at anything from 1 inch to maybe 7 inches.
Gavin…if this belongs to a different category I apologize in advance.
