A tech at First Texas has told me that these models, as far as he knows, will keep the hunting presets that a user sets up in disc and all metal when switching to all metal-no motion mode (Landstar,505, Time Ranger), Pinpoint mode (3300) and back again. I told him that as far as I knew, the 3300 would loose its presets when change modes like this. He told me that the 3300 has been updated to keep the presets that a user sets up in the disc mode and all metal mode. Can anyone please verify if all these models currently will keep their presets. Thank you for your help.
