... JEL is a great wreck and doable if he can put a blob up. ....
I must have dived this wreck 20 or 30 times and never used (and mostly never carried) a dSMB. You just need to go back to the shot line. A dSMB is needed in poor vis and current when you are unlikely to go back to the shot. The Layne/Scylla are very easy to get back to the shot.
