I didn't necessarily mean in 0 vis conditions, I mean SAR in general. Someone had me looking for a lost pair of glasses yesterday and I couldn't find them. I tried just corn rowing the area but it was hard to stay on track.
I'm just wondering if there are any good books on the subject or anything like that.
Sorry for the hijack eriediver.
some of the ERDI course materials are good, but follow @Lake Hickory Scuba 's youtube channel, Bryan has some good stuff on there and is starting to do a lot more with SAR on there.
Part of the problem with "corn rowing" the area is you really have to use a compass to do it properly as it is one of the more difficult patterns to execute.
This is a decent article on some search patterns. Obviously it requires a fixed reference point for either, and for the pier walk it requires both a pier and a second person. I will usually do arc search patterns if I'm looking for something and will use a reel with it attached to some fixed reference point. If searching from a dock, just tie it to the dock, ideally at the bottom, and if searching from a boat, just tie it to the end of the anchor. Expanding square is one that is much more complicated to actually execute but is quite effective. It again requires a compass though and is not ideal IME for diving in current as your square gets lopsided as you have no real reference to the starting location
