An underwater collection vacuum with custom aeration technology, size sorting capabilities, and an ergonomic friendly user interface.

Over 95% of the California’s bull kelp population has died off in the past decade. This can be attributed to the 10000% increase in purple sea urchin numbers. We decided to make an underwater vacuum with custom aeration technology and size sorting capabilities. The ergonomic device has a collection rate 6x higher than any other urchin removal method & will aid divers in clearing the urchin barrens.
