Daylight is a requirement, and you have to be mindful of your depth. Depending upon which periscope you are at, either <Page Up> or <Ins(ert)> just enough to clear the shears and have a slight visual forward. Don't strain your eyes too much though. It is a bit like driving through fog. Objects appear like ghosts through the mists... You might only see the cables if you are too deep for the mines themselves, but the cable can hook your boat and pull the mine down on top of you. I do not recall if there is a cable scraping sound or not... If anyone experiments with wandering into a minefield, be sure and let the others here know
... You can 'see' the nets this way also... Setting the speed with the knot dial to One (1) knot can help, but don't forget about the current and sideways movement
