Went to the WDJ and could'nt use my PI unit's due to the interference from so many detectors. There was so much rubbish my ML XT17000 drove me nuts too. In frustration I pulled my T4 out, got a token on the saturday and another on sunday, my T4 is modified and a dream to use. Did'nt win anything in the draws but was glad to find tokens in the 20 or so acres. I'll be using it in any future hunts to, what a great little machine they are. cheers Nugget.
