[QUOTE="oldtimerROB, post: 446055, member: 8947"] For prospecting for nuggets Impact does not need to be waterproof as we are in a mainly dry climate here in Victoria except for really wet years,maybe tropical Queensland you are right.The main thing about the Impact is its ability to detect in extreme ground on hills and sides of hills where the very high to extreme mineralisation makes for a high probability of finding nuggets, so a lot of people are missing out.I recently found a patch on the side of a hill near Maryborough, Vic missed by the old timers but it seems virgin ground and has been absolutely hammered by PI,s with holes every one metre and one place raked over. but the Impact used slowly found a legitimate target which the PI,s missed.It was 6 inches deep and a 2 inch long rough bit of rock encrusted with some black metal on it with pyrites which gave a medium pitch signal in DI3 mode.Deep mode I used in the gully downhill from there and found some steel and iron objects but on the hill it could not be ground balanced. All metal mode did not pick up this signal but I found it useful to locate it when it was dug up.No need to adjust the settings except switch to 20 Khz and lower the gain from 70 to 60 as this was extreme ground.I would prefer a 13 inch coil as an all rounder but a 15.5 inch is available for the Impact which may be a little heavy for me due to back problems.
