Eric (and others)
Further tests of ironstone bed revealed:
1) Significant depth reduction on all targets when the previously loose gravel was mixed and compacted with a similar crushed material
2) ERIC....I did the air test with the same settings as used with the ring (fast SAT and DELAY at about 50uS)....there was NO appreciable increase in detection distance
3) Having the THRESHOLD at approximately the 10 o'clock (silent search) position does help quieten the background noise, whilst preserving the signal definition. My usual setting for the THRESHOLD is about 11 o'clock
4) Changing the DELAY from 50uS to settings of 35uS and 40uS resulted in unacceptable ground noise
5) Wetting the whole test area reduced ground noise and consequently enhanced signal clarity
The ring I used is a fairly large 18k, with a thick circular profile. Any nuggets with a surface area of this ring and more, should be detectable even in the conditions described.
