Having knocked something, which then fell over and the movement silted the place out in a wreck I thought I knew well - found my way out more by luck than good management many years ago - unless I can see daylight _and_ not be in a tight squeeze to get in or out - then I'll run a line. I'll be more likely to start the line just out of sight within the wreck rather than outside having had a problem with a curious diver who followed my line in Scapa - I was coming out to find them coming in.....
 
However, for most recreational divers.... the use of a line is absolutely recommended. Wrecks kill over-confident and under-prepared divers. What is worse, is that under-trained divers can be oblivious to the risks until it is too late..

Acctualy, I have seen more of these divers die from getting tangled in their own line then from getting lost because because they did not have a line.

I use a line a lot and there are some wrecks I don't use one on. Drop me inside of the U-853 or U-352 and I'm very happy without a line. Put me in the engine room of the USS BASS, I'm OK without a line, put me in the after compartments of the same wreck and I'll run a line.

Progressive Penetration is only a tool in your tool box. It works when you have many, many hours on one wreck, it will not work on wrecks you only see once or twice. Use it when it is the right tool for that job.

There are no reasons to do a wreck penetration worth risking injury or death.

There's nothing in this [-]cave[/-] wreck worth dieing for.
 
Why is this an either/or situation?

The line is your backup.
