Standard practice is to use the anchor line as the primary descent and ascent line. Shooting a bag is only done if the hook has pulled, if you're lost and unable to locate the hook, or if you've had an equipment failure that makes an immediate ascent necessary. Using a small reel with nylon line makes for an upline that is easier to carry (though obviously not completely painless). There are ways to deploy the line so that it is, in theory, recoverable from the surface. I've been able to pull this off, but I think some luck is required. Generally, the wrecks here are so well covered in fish nets and monofilament that another hunk of line isn't going to make all that much difference anyway. Several folks have suggested that a guideline reel would be a good alternative. None of them, however, dives here. While I think it might be a good idea, I have to wonder about the breaking strength of guideline (#36 I guess) relative to what's really needed. The nylon line I carry is 1/8 inch braided, which is very, very strong. It might be overkill. One suggested the same reel used for navigation could be used as an upline. One potential difficulty with that would be the equipment failure scenario, where you're away from the hook on the guideline and need to ascend from your current location. It is possible that there's not enough line left on the reel to do that under these circumstances (especially if the reel is loaded with #36). This would indicate the need for a backup ascent line, and we're back to carrying two reels with heavy enough line to use for that purpose. > For that matter, why not run a continuous guideline from the hook > and just return to the anchor line at the end of the dive? Actually, from "near" the hook. We would NEVER tie onto the hook, since if it pulls, we're no longer connected to the wreck (I use a secondary tie, too, but wonder if that would hold). This is the expected normal practice. The upline is only intended for use when this method fails. Art Greenberg artg@ec*.ne* -- Send mail for the `techdiver' mailing list to `techdiver@aquanaut.com'.
