Can vouch for the SDC, gold every trip.
Me too. Always get something - 100% record with mine since about Aug/Sept last year (didn't detect for 10 weeks Nov/Dec/Jan though). Worst swing lately was 5 for 0.61 gram but most are 1>2 gram totals. Haven't been able to put a full day in for awhile so been happy with what I'm getting in the time I've had available.
They really do pick them up well in the worst ground too. Don't worry about the smalls - they add up. My smalls vial has over 16 grams in it at the moment.
