| There doesn't seem much of a decision to me - go get him.
I'd follow all the way back to the bottom if I could still see him, and in some circumstances if I'd lost sight en-route - since if you don't you're certain he's dead.
There are times that it'd be foolish to go after him; such as if the 60m dive was on a wall and he was heading past way past your MOD with no signs of stopping, or if you're already dealing with another emergency.
To paraphrase one of the instructors (not sure which) from when we discussed deepish rescues on the ITC: if you're not prepared to rescue your team-mate on an ocean dive you shouldn't be doing the dive unless you have support divers to complete the rescue for you. Clearly, this is going to put you in harms way all part of why selection of team members for "bigger" dives is so important.
