Sanders beach is a popular spot for 2 reasons. For new divers this is one area used for OW classes. If you enter and head left if has a very gradual slope down to the 40' range. At about 30' there is some PVC "boxes" suspended in the water that is used to practice buoyancy.
If you head to the right there is a line leading under the docks where there is a couple of sunken boats under the docks. While this is not a total overhead environment there are lots of cords, pipes, wires, fishing line, ext that you can get caught up in along with being under docks and boats.
Next time we dive there I will get some pics and much better descriptions up.
