I normally allow the surface team to pull it in. We have D-rings every
3m to allow us to hang stages etc if required from the buoy, the whole
thing can be left floating if there is difficulty with the pick up and
retrieved later on. Our tape bag has a small lead weight in it so the
system is deployed totally remote from yourself so avoiding hang ups.
