Title: White's Surf PI Dual Field (any ideas please) Post by: congerman on November 14, 2013, 10:02:24 PM I have been out with my White's Surf PI Dual Field getting used to the settings but there are A few things confusing me the machine is new when searching on the tide line I can't get A steady threshold At the moment I am running it on
pulse delay,, 7 o'clock gain control,, factory settings threshold ,, ( chartering just audible) The problem I have is that when moving the coil searching I am getting the same noise as when I lift the coil 1--2 ft away from the ground like the threshold is too high the noise gets louder at the ends of the sweep ??? I have been using A cover on the coil to protect it could this be the reason why its doing it if water is getting trapped under the cover and moving between coil + cover can anyone give me any ideas why its making the noises is it normal or is it faulty ??? I am finding targets x10 decimals x6 bobby pins (hair clips) and the usual scrap not bad in x2 short trips x5 hrs in total Title: Re: White's Surf PI Dual Field (any ideas please) Post by: Chef Geoff on November 14, 2013, 10:56:14 PM it's unlikely to be water moving about as the covers are pretty tight. check that you haven't got too much spare coil cable at the coil end, the slightest movement of the cable will register as a target and at the end of swings is where this movement would happen ???
