Multiple units can be towed behind a single boat. Seas should be 3-4 feet or less. Recommended towing speed is 2-3 knots, but techniques are available to attain 5 knots for long hauls. Artificial reefs function better when they mimic nature. The balls which create holes are inflated to different pressures to vary hole sizes.
Interconnected holes are possible by inflating the balls until they touch.
Additional casting techniques are taught by our trainers so users can customize to fit any need. A variety of surface textures that enhance the settlement of marine life are available. A popular surface texture is made by spraying sugar water onto the surfaces of the mold before casting. A rough stony surface is exposed by rinsing the module with a garden hose. All surfaces are enhanced by the use of an air entrainment admixture.
