Wednesday got one and it was a solid 14, cked it on all freqs and was solid at 14. Today got another that read 20, solid 20. About 6" and a war! Park 1, 5 tones, with bins set to highlight nickels (10-14) and volume up for that bin. Sense at 23, Recovery at 6 and bias at 0. I also cranked the first bin up to 9 from -9 to +9, then the nickels bin, then a lower volume and tone for 14-18, then a med High volume for 18-13, then a high volume and tone for the remaining. 9" is nothing for the 800! Many, many wheats and others, plus several silvers at 7 to 10".
