Map of U-869 (Wrack)

U-869 (Wrack)

New Jersey · 60–73 m

U-869 is a WWII German Type IXC/40 U-boat lying in about 230-240 ft of water roughly 60 miles east of Point Pleasant, New Jersey. Discovered in 1991 by a team led by Bill Nagle and John Chatterton and finally identified in 1997, the mystery wreck ('U-Who') was made famous by the book Shadow Divers; three divers died exploring it before identification. It remains one of the US East Coast's premier expedition-level technical wreck dives - trimix decompression diving for experienced teams only.

Map of Vortex Spring

Vortex Spring

Florida · 1.5–35.1 m

Vortex Spring is the largest commercial dive facility in Florida, a privately run spring resort in the Panhandle near Ponce de Leon producing about 28 million gallons of 68°F water daily. The 200 ft diameter basin slopes to a cavern entrance at 58 ft, with a gated cave continuing to 115 ft for certified cave divers (measured passage ~1,640 ft). Resident freshwater fish and even introduced koi make the shallow basin a favorite for open water training and check-out dives.

Smithtown Reef

New York · 9.1–12.2 m

Smithtown Reef is a 31-acre NYSDEC artificial reef in Long Island Sound about 1.6 nautical miles northwest of the Stony Brook Harbor entrance, in 30-40 ft of water. Built from two vessels, six barges, steel pipes and concrete-filled steel cylinders, it offers good relief for tautog, black sea bass and scup. Visibility is typically 10-20 ft and tide-dependent—an intermediate Sound boat dive.

Map of Suck Em Up

Suck Em Up Verified

Hawaii · 3–8 m

Suck Em Up is a shallow North Kona boat dive built around lava tubes, cavern-like passages, skylights, and the pulsing surge that gives the site its name. It is shallow but not trivial: buoyancy and overhead discipline matter because the passages can be tight and surge can push divers around. Use it as a guided boat cavern/swim-through site, not as a technical cave dive.
