Several folks have asked about the course Janet (JAG) and I run at CCSP so here it is. Its 45-60 minutes long with no stops and covers most of the "attractions". Its almost all compass work.
Note that as we get to any particular destination, we realign ourselves next to that destination before we take off again. Visibility being what it is, you don't want to be 15 feet from a destination as you start off for the next one or you're likely to miss that next one.
At the "Grapevine Scuba" dock (the northern most wooden dock) swim out mid way to the opposite wall. Drop down to about 20 ft.
On a 220 heading, you'll hit a platform after a few minutes. That platform has a blue paint job as an underwater identifier.
Stay on 220 and in fairly rapid succession, you'll hit 3 more platforms. The last platform has 4 nickle sized holes drilled into the left vertical leg as you approach it. That's how we know we've hit the last platform and need to change course. Sometimes we loose count of how many platforms we've passed and the 4 holes are what we go looking for.
On a heading of 200, you'll next hit the boat in short order. If you're slightly off course to the right, you might see a stick in the mud that looks a bit like a street sign. The boat would be 20 feet to the left. Get to the front of the boat before you take off again.
On a heading of 200, you'll spend several minutes in open water getting to the next destination - Sisco the Shark. Normally we get there at the 19 minute mark. Because its quite a distance away, you may end up slightly to the left of Sisco and arrive at a large rock wall with a cave like depression that undercuts it. If that happens to you, Sisco's tail is to the right. Get to Sisco's nose before you take off again.
On a heading of 315, you'll be in open water for a while and then you'll hit a platfom about 30 seconds after you start to see the bottom again. Usually we are just slightly to the right of that platform as we come up on it so look to your left.
On a heading of 40, you'll run fairly shallow initially and after a few minutes arrive back at the boat. Typically we're a bit left of the boat where the "street sign" is. Get to the back end of the boat.
On a heading of 20 you'll hit platform 4 again - the one with the 4 holes.
On a heading of 40, you'll hit platforms 3, 2, and 1 (blue) again because you're now just running the recip course.
When you get to the "blue" platform, stay on your heading till you see the bottom start to disappear. At that point, drop your compass and just follow the contour at about 20-25 feet.
After several minutes, you'll spot a 2 inch diameter stick vertically in the mud at about 25 ft. The "Grapevine Scuba" dock is up slope.
We normally get to this point in 45 minutes.
If you miss that stick, you'll come across a 4 inch tree branch stuck vertically in the mud a bit further on down, again at about 25 ft.
If you keep following the contour, you'll eventually hit the 2 northern most platforms that are next to each other. A heading of 60 from the eastern most platform will bring you to the coffin at 45 very cold ft.
From the coffin head east to the wall opposite the "Grapevine Scuba" dock.
Follow that wall southerly looking for two 1 inch pieces of PVC pipe at about 30 feet. One pipe is vertical in the mud and the other is horizontal in the wall. They are next to each other. At those pipes head 310 back to the 2 inch diameter stick and the "GrapevineScuba" dock.
Mission accomplished - tank pressure low, except if you're Tropicgal. I think she can run the course twice on a 63.
