So I hunt very mild ground around colonial cellar holes. Searching for copper and silver coins and of course Relics like buttons and stuff.....Those pesky square nails like to mask the goods,but the idx does pretty good...with the woods here in New Hampshire stuff sinks deep due to frost,snow,and lots of leaves. My average finds are 5" to 10" deep. The whites IDX can hid large buttons and large cents at 7 to 9" max. I use the 9.5 bluemax coil and it does pretty darn good in depth and separation it seems.. So will a Whites sst be any better at the type of hunting I do ? Will I get similar depth? Will the recovery speed be just as fast or faster ? I understand the sst has no disc knob and iam OK with that as I dig everything that's non ferrous. I just curious if the 6x10 DD eclipse will get the same depth on the sst as the 9.5 coil on a idx... I know it's alot to ask but has any one really gave the sst a good hard test. I really like the IDX ,however i would like some tones ! And ground balance and a higher resolution on the visual ID... Any thoughts would be greatly appreciated .......Oh yea one more thing.....the IDX has a much lower freq.....which seems to bite those largecent good at 7+ inches with a nice smooth tone .....do you think the sst can hit hard on deeper silver and copper with its higher freq ?....OK iam Done Know . thanks !
