Package Content:\n1x 2\" double ball mount arm 2x free replacement O-rings Upgrade your\nunderwater photography with the buoyancy floating arm. Designed as an\nessential part of any scuba diving camera system, it serves as a light arm and\nbalances the weight of your equipment underwater, reducing strain on your arms\nand wrists. To calculate the buoyancy needed for your camera system, determine\nthe weight of your underwater set by using a hanging scale when it is\nsubmerged in water. Make sure to keep the scale above water as most models are\nnot waterproof. Then, choose floating arms or floaters with sufficient\npositive floating capacity based on the weight of your set. Ensure that you\nhave a balanced setup on both sides.

The surface of the buoyancy floating arm is black, giving it a simple appearance with an inner diameter of 1 inch. 1pcs of floating block provides -175g buoyancy. Package includes: 4x buoyancy kits, 1x storage bag, 2* 4\" double 1\" ball extension arm, 2* free replacement O-rings.\u003c\/li\u003e\n         \u003cli\u003eHigh Quality Material: Arm made by corrosion resistant anodized CNC aluminum alloy, Anti-corrosion. The hollow design makes it lighter and reduces resistance when used underwater. Made from premium polymeric materials, the buoyancy floating arm can withstand the harsh underwater environment, ensuring long-term use.\u003c\/li\u003e\n         \u003cli\u003eSuperior Buoyancy: Our underwater buoyancy kits are engineered to provide high buoyancy, thanks to its high-density, high-hardness, and strong compressive strength properties. It can withstand up to 5 bars of water pressure, less than 2% deformation at 41 meters underwater without deformation, and maximum depth 50m\/164ft.\u003c\/li\u003e\n         \u003cli\u003eFree Extension: 4\" Double 1 inch Ball Arm supports to connect strobe or video light, Freely adjust the angle to get the best lights angles to take the best photo you want. Float block is compatible with various YS\/double ball light arms and underwater tray on the market, including Seafrogs, nitescuba, Starbea strobe arms. More easy storage you can either put on your arm or store in air mesh bag.\u003c\/li\u003e\n         \u003cli\u003eMore Efficient: More light weight and cheap compare to a traditional carbon float arm, 51g self-weight buoyancy block provides -175g buoyancy and you need a 155g carbon fiber float arm can provides 300g float. The float block will not flood and affordable. Allowing you to add or remove floats to achieve the perfect amount of buoyancy for your camera system, depending on shooting style and conditions.\u003c\/li\u003e\n  \u003c\/ul\u003e","brand":"MINIFOCUS","offers":[{"title":"Default Title","offer_id":44381786570932,"sku":"B0CDH426RQ","price":271.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0595\/9906\/1172\/files\/B0CDH426RQ.jpg?v=1789135941","url":"https:\/\/auspowers.com\/products\/minifocus-4pcs-underwater-camera-buoyancy-kits-4-double-ball-aluminum-alloy-extension-arm","provider":"AusPower Australia","version":"1.0","type":"link"}
