Mambo Dave, what pier are you talking about?
EDIT: I looked above and you probably mean Anglin's Pier. I rarely dive up there but it surely is a lot closer swim to the reef than where I normally go. I dive South Broward and go waaaaaaay out. I also kayak dive just north of Sunrise and we go out to the mooring balls.
yeah, I meant LBTS's Commercial (road) pier. It has to be just about one of the easiest, nicest places for a shore dive in the United States. There is even a line of coral structures that aren't as far out as the end of the pier (sometimes mistakenly called the first reef, but it's just a small inner reef). The first reef is out past the pier a little.
There is a ledge out there that (seemingly sometimes) has white mooring balls. That one IS a 20-30 minute kick out. It's a nice ledge, but not nearly as scenic as the corals closer in. Heck, that big kick-out ledge is tough even for experienced divers to make. More than one time I've instructed a diver to grab the rope ahead of the dive flag and drug them out there (we kick out on top, on our backs, to conserve air - it's a less efficient kick, and tougher, but it saves the back gas).
I think I have dived the ledge you're talking about a couple of times (is it a ledge that faces the shore (west) off of Dania Beach Blvd.?). The far-out ledge at LBTS faces east.
And this brings up another really important point for newer divers (solo or with a buddy - though solo should dive a place they know is good): There really aren't too many great close-by kick-out places in any state, any city or road. Some people get used to what we have here, north of Ft. Lauderdale, and makes trips either a few miles south or north of here that end up with nothing but sand (I've had a few friends insist we dive north of here, but with absolutely miserable results... well, I did get a lifeguard girlfriend out of it once but, still....).
Even the places that seem like they'd be good for just a sand dive for skills can end up crappy. North of here, in nothing but sand, we encountered such strong currents that, by the time we canceled the dive, put us a mile away from our entry point. A newer solo diver needs to know the area they are going to solo dive in, and know it well, from actual experience with buddies who have taken them out.
