M60 tanks undergo a thorough cleaning before use as reefs
The Artificial Reef Program used four types of obsolete Army armored vehicles as artificial reef materials off the New Jersey coast. These were cleaned at local military bases, loaded onto barges for transport, and pushed off at their final destination. Once the Army had disposed of its excess inventory, the program ceased, around 1999. The Artificial Reef Program has sunk almost 400 tanks altogether, far too many to list them here in this website.

Delaware has a string of artificial reef sites in the Delaware bay, but they are of little interest to divers. Most of the sites are quite shallow and perilously close to the shipping lanes, several of them were actually reduced for this reason. The conditions in the bay are hardly good for diving. The reefs consist mostly of concrete rubble from construction in Philadelphia and other cities on the river. Also shown is New Jersey's sole artificial reef in the bay.
A wreck reel should be considered standard equipment on all but the easiest open ocean dives. Even if you aren't into wreck penetration, you can use the reel as a foolproof way of always knowing how to get home. Just clip it on, and off you go. This is much easier and more reliable than any other means of navigation, and is useful in many situations, especially in poor visibility. Among other things, a wreck reel will allow you to make explorations over featureless sand areas, and in confusing debris fields, like the Mohawk, as well as conduct organized searches, etc. In open water, a wreck reel is often more useful than a compass, although you should always carry one of those as well. On the other hand, there is no real use for a wreck reel in a typical inlet or jetty dive, whereas your compass will be extremely useful.
