An excellent alternative to glass sphere flotation, DeepWater Buoyancy’s Hardball® Floats provide subsea buoyancy for a wide variety of oceanographic applications. Made for the demands of subsea moorings, as well as the rigors of handling on the decks of vessels, HardBall® Floats are built of strong solid materials for years of reliable service.
No need for a protective covering. No need to handle carefully. No need for regular inspection and maintenance. No danger of implosions at depth. Just rugged, versatile subsea buoyancy – The Solid Choice.
Available in a wide range of sizes and depth ratings the HardBall® Float lives up to its name. The buoyant core of the float is made of only the highest strength, epoxy-based DeepTec® solid syntactic foam – no macrospheres or other high-risk fillers are used. Thick-walled, high-density polyethylene exterior for maximum impact and abrasion resistance. This durable shell also provides resistance to biofouling.
