I dove SeaTech Ledges in November 2025, by shore entry at Dania Beach, Florida.
SeaTech Ledges are natural reef formations located on the other side of Dania Pier to the Erojacks, featuring deeply undercut ledges covered with coral and invertebrates.
Starting about 1,200-1,800 feet (366-549 m) offshore (roughly a pier and a quarter length). They form the west-facing wall of the first reef and run north to south.
This is a more challenging shore dive than the Erojacks due to the longer surface swim, but the ledge formations make it worth the effort!
How to Get There
Park at the Dania Pier parking lot located at 300 N Beach Rd, Dania Beach, FL 33004.
Reach the beach from the southern most point of the parking lot and find the black flag in front of the pink tower. You can enter the water here.
If tank weight is an issue, bring a gear cart.
From here, swim north east until you're in front of this navy blue tower, and 1.25 pier lengths out.
What Marine Life I Saw
The ledges create depths ranging from about 25 feet (7.6 m) on the sandy bottom west of the reef to 14 feet (4.3 m) on top of the reef.
These are some of the best reef ledges within beach diving distance in South Florida, and the structure creates perfect habitat for marine life.
You can expect to see lobsters, hogfish, grouper, colorful reef fish, sea cucumbers, octopus, nurse sharks, moray eels, and rays.
During lobster season (with proper licensing), this is a popular hunting spot. Spearfishing is also permitted at this site.
Safety Considerations
The main safety consideration is the long surface swim make sure you're physically prepared and properly conditioned before attempting this dive.
Use a dive flag as required by Florida law.
Like the Erojacks, expect boat traffic overhead. The ledges run north-south, making navigation relatively straightforward, but currents can be mild to moderate, so plan your dive accordingly and be aware of conditions.
Conditions
The best time to dive SeaTech is on a calm day with light winds and seas under 2 feet (0.6 m). Anything more makes the surface swim significantly harder.
I check the Windfinder Website or App to check the wave direction, tides, and wave heights.
Living in Miami, my trick to know whether Dania Beach is fine to dive, is to first check the underwater cameras located nearby.
These are the ones I check:
While these cams aren't Dania beach, they're very close and experience near identical conditions.
You can also call local dive shops and ask them the latest visibility report.
An incoming tide generally means better visibility and a more manageable swim back to shore.
Visibility typically ranges from 20-40 feet (6.1-12.2 m) on a good day but can drop significantly after rain or strong winds.
