SEAC BCDs — Modular, Rear-Bladder Performance
SEAC's BCD lineup covers everything from an accessible jacket-style entry BCD through a modular, dual-tank expedition rig — all built with the Italian brand's consistent focus on durability, fit, and practical function. The modular Seac Modular Max and Modular are the standout designs, built for divers who want to customize and reconfigure their buoyancy setup across different dives without buying multiple complete systems.
At DiveCatalog.com, we carry the current SEAC BCD lineup as an authorized dealer.
The SEAC BCD Range
Seac Smart — Accessible Jacket-Style Entry
The Smart is SEAC's compact, travel-friendly entry BCD — a traditional jacket-style buoyancy compensator with a reinforced bladder, quick-release weight system, and separate pockets on both sides for weights and accessories. Built for beginner divers and frequent travelers who want dependable, straightforward gear without excess bulk. Outer bladder is PU-coated Cordura 1000 with a PU-coated Cordura 500 inner for durability.
SEAC EGO — Rugged Traditional BCD
The EGO uses 1000 Denier Cordura for high abrasion resistance and long-term durability. Four stainless steel D-rings (two on shoulder straps, two under side pockets) provide gear attachment points throughout the dive. Three dump valves with pull commands support buoyancy control from multiple body positions, and external size labels make quick identification easy for dive shops and rental operations.
SEAC EQ-PRO — Harness-Style, Body-Mapped Fit
The EQ-PRO's Frame to Back system starts shoulder strap adjustments at the backpack, keeping weight distributed evenly and preventing harness warping across body types. A single center buckle provides quick on/off, and 3D mesh inserts reduce rubbing for both men and women across a wide range of body shapes. An independent bladder design reduces abdominal squeeze for extended comfort on long dives, and the low-drag silhouette improves hydrodynamic performance underwater.
Seac Modular — The Customizable Rear-Bladder BCD
The Modular is SEAC's flagship BCD, built for demanding divers who want to configure their setup for different dives rather than buying separate BCDs. Cordura 1000 and 3D mesh harness, Frame-to-Back shoulder strap system, aluminum D-ring and belly buckle, trim pockets for up to 2kg with Velcro quick-release, removable crotch strap, and a donut bladder with piston inflator. Every part of the Modular is interchangeable — pockets, bladders, backpacks, and trim configurations can all be adjusted and replaced independently as your diving evolves.
Seac Modular Max — Dual-Tank Expedition Configuration
The Modular Max extends the Modular platform specifically for dual-tank use, with a 44 lb donut bladder in 1680 Denier Ballistic Nylon and an internal air chamber in polyurethane, two quick discharge valves positioned for fast dump from any body position, two ditchable weight pockets, and four anodized aluminum D-rings. Standard gauge eyelets allow the backpack to accommodate different bladder and harness configurations using standard straps and fasteners. At 6.8 lbs, it disassembles quickly for compact packing — genuinely practical for dive vacation travel with a properly configured technical rig.

Frequently Asked Questions — SEAC BCDs
What does "modular" mean in the context of the Seac Modular BCD?
Every component of the Modular BCD is interchangeable — harness, bladder, backpack, pockets, and trim pockets can all be adjusted, replaced, or reconfigured independently. This means the same harness and backpack can support different bladder capacities for different diving configurations, without needing to buy an entirely separate BCD.
What is the Frame to Back system on the EQ-PRO?
It's a harness design that starts shoulder strap adjustments at the backpack rather than the shoulder, distributing weight more evenly and preventing the harness from warping or shifting out of position across different body shapes.
Can the Modular Max be used for single-tank diving?
The Modular Max is designed specifically for dual-tank configurations, with a backpack and bladder system built around that use case. The standard Seac Modular is the more appropriate choice for single-tank setups.
