I posted this question on another forum too trying to get some clarity.. It seems to me after reading the manual a few times that Park 1 and Field 1 might have the same Multi-Frequency Weighting.. Same with Park 2 and Field 2.. Are the only differences between say Park 1 and Field 1 the stock discrimination pattern, tones, Recovery Speed and Iron Bias settings?  If this is the case, I can use Field 1 to basically make another custom Park 1.. This would be good to know.. Bryan
