Diving atUS Army Tanks (United States)
Navigating the US Army Tanks site requires attention to potential overhead hazards from boat traffic, especially given its popularity. While not a strong current dive, conditions can shift, and proper surface signaling is always a good practice. Divers should plan for a maximum depth of 14 m (45 ft), a consistent depth for exploring the twin M-60 wrecks. These Vietnam War era tanks, intentionally sunk in 1994, provide structure that can attract larger marine life, including sharks, which divers should observe respectfully from a distance.
Tonight's objective overview for US Army Tanks shows an air temperature of 25.7°C. The measured surface conditions include wave heights around 0.4m. This environmental data is logged for the close of the day.

Dive Site Overview
A compelling dive into history and artificial reef development awaits at the US Army Tanks. Two M-60 Vietnam War era tanks, purposely scuttled in June 1994 by the Department of Environmental Resource Management (DERM), anchor the site.
Despite their relatively short time underwater, these tanks display substantial marine growth, appearing much older than their actual deployment suggests. Spiny oysters, various sponges, and both hard and soft corals extensively colonize the metal structures. Surrounding the tanks, 1060 tons of lime rock boulders extend the habitat.
This thoughtful deployment has resulted in an area prolific with diverse life, notably providing abundant hiding spots for lobsters and other bottom-dwelling creatures. A dive here is typically straightforward, reaching a maximum depth of 14 m (45 ft) on a sandy bottom, making it accessible for Open Water divers.
For extended exploration, the site can serve as the starting point for a longer drift dive, leading to other nearby wrecks like the Radio Tower pyramids, the Matthew Lawrence, Larsen Barge, Miss Karlene, Patricia, and the John Koppin Barge. It's an example of how human artifacts transform into thriving underwater ecosystems.
Best Time to Dive
Optimum conditions for diving the US Army Tanks generally align with the warmer, drier months, although good diving is available year-round. From July through August, conditions are frequently excellent, with average air temperatures peaking around 28.3-28.4°C (83-83°F). During this period, rain levels are moderate, averaging 4.3 to 6.0 mm (0.17-0.24 inches), and wave heights are at their lowest, often around 0.39-0.49 m (1.3-1.6 ft), contributing to calmer surface conditions. However, the site maintains good dive scores throughout much of the year, including spring and autumn. Even in winter months like January and February, air temperatures remain mild, averaging 19.8-20.5°C (68-69°F) with minimal rainfall, typically around 1.5-1.9 mm (0.06-0.07 inches). Wind speeds also tend to be lower in the summer, making boat entries and surface intervals more comfortable. While water temperature data isn't consistently reported, it generally mirrors surface air temperatures in shallower coastal areas, suggesting warm water during peak summer months.

Dive Experience & Conditions
Visibility at the US Army Tanks site varies with ocean conditions but is generally good for this area. Expect to find a sandy bottom at a consistent depth of 14 m (45 ft). Once submerged, two M-60 tanks become the focal point, resting upright and allowing easy exterior exploration. Wrecks are heavily encrusted with growth, appearing ancient despite their relatively recent artificial reef status. You'll observe a variety of spiny oysters, sponges, and corals covering the tanks, providing shelter and sustenance for numerous reef fish. Nearby, lime rock boulders extend the habitat, creating more nooks and crannies for marine life, especially lobsters. While strong currents aren't typically expected, divers should monitor local conditions; an optional drift dive extends to other nearby wrecks. Such a dive allows for a longer, more varied underwater journey if conditions permit.
Dive Difficulty & Safety Guidelines
An expert tip for diving the US Army Tanks involves careful dive planning, particularly if considering the optional drift dive to additional wrecks. Always verify current local conditions with a knowledgeable dive operator to assess visibility and any potential currents. The site's maximum depth of 14 m (45 ft) is well within recreational limits, making it suitable for Open Water Divers. Responsible diving practices, including staying within no-decompression limits and monitoring air consumption, are always paramount. Though not explicitly identified as a hazard, boat traffic can be a concern at the surface, so deploying a surface marker buoy (SMB) upon ascent is a wise precaution. Respect all marine life, maintaining a safe distance from any larger species like sharks that may be present. Avoid disturbing the delicate coral and sponge growth on the tanks and surrounding boulders.
