The Halcyon Eclipse buoyancy compensator is establishing a new standard
for single-tank diving while creating unprecedented streamlining and
eliminating the many useless “features” that clutter traditional
buoyancy compensators. The Eclipse wing has a long, narrow profile that
supports the diver’s single tank along his or her entire length,
preventing unnecessary drag and minimizing in-water effort. Meanwhile,
the infinitely adjustable harness prevents the frustrating lack of
control found with typical buoyancy compensators. This added stability
reduces drag by encouraging a streamlined position — these changes
result in less effort and more diving fun.
