tidal river inlet with stone jetties or bulkheads on both sides
Depth:
30 ft
This inlet has a long slightly L-shaped jetty on the north side and a longer straight jetty on the south side. Both jetties are made of large stones and concrete, and the ends are built out of man-made concrete "jacks", shaped like an H with a 90-degree twist in the middle.

The Manasquan River is overall not as nice a place to dive as the Shark River. The currents are stronger, the water never seems as clean, and the bottom is silty wherever it is not covered with mussels. The inlet jetties can be downright dangerous, and the boat traffic in the channel there is often very heavy. Off the north jetty is the so-called "Manasquan Wreck", but this is a long swim from shore and probably best approached with a boat.
In the murky waters off New Jersey, you are going to need a powerful dive light if it is to be of any real usefulness. There are many different types of underwater lights to choose from.
Bulb Type
Nowadays, LEDs are the only way to go. They are cheap, bright, and efficient. They throw a white light that is much better than the dingy yellow of the old incandescent technology. Incandescent lights are completely obsolete. HID lights were never reliable, and terribly expensive.
Beam pattern is probably more important than brightness, Your main light should throw a wide beam, for area illumination. Many lights throw a narrow pencil beam that appears to be brighter but is actually less useful. These are best used as backups and in special situations, such as camera strobe aimers. Some lights are adjustable.
