{"title":"Atolls","description":"\u003ch2\u003eAtolls: Safety and freediving\u003c\/h2\u003e\n\u003cp\u003eIn freediving, line training requires a \u003cstrong\u003efixed, stable, and highly visible surface reference point\u003c\/strong\u003e that the freediver can hold onto before the dive, use to recover energy between breath-holds, and attach ballast for FIM (Free Immersion). This role is fulfilled by the freediving atoll: a storage buoy designed to withstand intensive use in open water and in the pool, with clearly defined structural features that distinguish it from simple diver-down marker buoys intended for spearfishing.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003eAtolls\u003c\/strong\u003e category at Deep Blue includes complete atolls, replacement inner tubes, and accessories such as lines, bottom plates, flags, and flag holders.

They allow the atoll to be inflated immediately and put in the water without purchasing additional components. This type includes the Apneautic models, available in Standard and Large versions, and the C4 Tavolara Buoy, a storage atoll with a construction approach focused on high-quality materials.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAtolls without inner tube and replacement inner tubes:\u003c\/strong\u003e the structures are sold separately. This configuration is intended for users who already own a compatible shell or inner tube and want to replace or add only one of the two parts, or for those who prefer to choose the inner tube independently based on the desired volume and valve.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAtoll accessories:\u003c\/strong\u003e the catalog includes removable diver-down flags in short and long versions (Best Divers) and flag holders compatible with Mares atolls, ropes, and bottom plates. These components allow users to maintain and customize the atolls they already own.\u003c\/p\u003e\n\u003ch3\u003eRopes and bottom line systems for freediving\u003c\/h3\u003e\n\u003cp\u003eBottom lines are among the most technical products in the category. The \u003cstrong\u003eStar Rope\u003c\/strong\u003e and the \u003cstrong\u003eProrope Rope\u003c\/strong\u003e, produced by Deep Blue, are lines designed to withstand the stresses typical of repeated underwater use. Available in multiple length options, they pair with the \u003cstrong\u003eMares bottom line plate\u003c\/strong\u003e and the \u003cstrong\u003eApneautic bottom line ballast strap\u003c\/strong\u003e, components that stabilize and weight the line in its vertical position during depth dives. These systems are used in depth training and guided freediving disciplines, where the straightness of the descent and the stability of the vertical path depend on the quality and correct ballasting of the rope.\u003c\/p\u003e\n\u003ch2\u003eHow to choose a freediving atoll\u003c\/h2\u003e\n\u003cp\u003eThe choice of atoll depends on several technical parameters and the intended use. Here are the main criteria to consider.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSize and buoyancy:\u003c\/strong\u003e the Standard version (600 mm diameter, 45 liters internal volume) is suitable for a single freediver training in FIM or STA (static apnea) without the need to load very heavy ballast. The Large version (700 mm, 70 liters) offers greater buoyancy, suitable for those using significant ballast for neck weight or dynamic ballasting, or for group sessions where several people hold onto the same surface buoy.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStorage compartment:\u003c\/strong\u003e all Apneautic atolls and the C4 Tavolara Buoy are equipped with a central compartment with lid. The compartment volume (10 liters for the Standard version, 16 liters for the Large) determines how much rope can be stored inside: Apneautic atolls are designed to accommodate 10 and 12 mm diameter ropes up to 100 m long. This aspect is important for open-water training at considerable depths.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInflation valve:\u003c\/strong\u003e the Apneautic inner tube with included valve is compatible with its own atolls, while the Omer inner tube is specific to that brand’s Boa Atoll model. Checking compatibility before purchase is essential to ensure proper sealing and correct inflation pressure.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePortability and transport:\u003c\/strong\u003e the C4 Tavolara Buoy comes with a polyester carry bag, which makes transport easier and protects the buoy between sessions. Once deflated, Apneautic atolls can be folded, but the rigidity of the PVC requires adequate storage space.\u003c\/p\u003e\n\u003ch2\u003eMaterials and technical features\u003c\/h2\u003e\n\u003cp\u003eThe products in this category feature construction solutions specifically designed for use in marine environments and in the pool.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMain fabric – PVC-coated polyester:\u003c\/strong\u003e this is the dominant material in Apneautic atolls and in the C4 Tavolara Buoy. The polyester structure provides mechanical strength and dimensional stability, while the PVC coating ensures waterproofing and fast drying of the outer surface. The material does not absorb water, a feature that reduces weight during recovery and transport.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eImpregnated nylon reinforcement bands – C4 Tavolara Buoy:\u003c\/strong\u003e the Tavolara incorporates reinforcement bands made of woven nylon impregnated with water-repellent material. These bands absorb mechanical stress at attachment and load-distribution points, such as the D-rings and handle connections.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePES straps and handles:\u003c\/strong\u003e on Apneautic atolls, the side straps and lower strap are made of PES (high-tenacity polyester). These serve as handles for the freediver at the surface, while the lower one is equipped with stainless steel D-rings for connecting ballast.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eYKK zippers: \u003c\/strong\u003eYKK zippers are recognized in the industry for their resistance to prolonged use in wet and salty environments.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDrain holes:\u003c\/strong\u003e two circular holes in the lower part of Apneautic atolls allow any water that may have entered the structure to drain quickly, maintaining stable trim and reducing the overall weight of the buoy in the water.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTelescopic diver-down flag:\u003c\/strong\u003e atolls in complete versions or with a specific accessory are compatible with removable diver-down flags. The telescopic system on the C4 Tavolara and the side housing on Apneautic atolls allow the flag to be mounted and removed quickly. The Best Divers flags available in this category are offered in short and long versions, with a removable pole for transport.\u003c\/p\u003e\n\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003e\u003cstrong\u003eBottom lines:\u003c\/strong\u003e Star Rope and Prorope Rope are built with multi-filament structures specifically selected to resist wear from contact with salt water and to maintain vertical tension without excessive twisting. The line ballast—made with lead elements or strap systems—must ensure the rope remains perpendicular to the surface, a necessary condition for proper free-descent training.\u003c\/p\u003e\n\u003ch2\u003ePractical use\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eOpen-water line training:\u003c\/strong\u003e the atoll is anchored to the bottom using a rope and ballast. The freediver holds onto the side handles at the surface to perform recovery breathing and pre-dive preparation, and the descent takes place vertically along the line. The storage compartment holds the coiled rope, which pays out progressively during the descent. This system eliminates the need to hold the rope by hand or rely on external structures, allowing the freediver to focus on the dive.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFIM – Free Immersion:\u003c\/strong\u003e in FIM, the freediver pulls along the line using the hands, both during descent and ascent. The atoll must provide a solid attachment point and enough buoyancy to compensate for the freediver’s weight during recovery. Large models, with internal volume up to 70 liters, are particularly suitable for this type of dive.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGroup sessions and freediving schools:\u003c\/strong\u003e in freediving schools and clubs, atolls are used to manage multiple freedivers around the same dive station. Stability in the water and the visibility provided by the diver-down flag are critical factors for group safety.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePool sessions:\u003c\/strong\u003e some atolls are also used in the pool for DNF (Dynamic No Fins) or DYN training, attaching the buoy to a lane as a reference and recovery point. In this context, zipper durability and stable trim in flat water are key.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSurface signaling:\u003c\/strong\u003e the diver-down flag mounted on the atoll signals the presence of people in the water to surface navigation. The Best Divers flags available as separate accessories allow users to upgrade or replace the flag on atolls from different brands.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch2\u003eAvailable brands\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eApneautic\u003c\/strong\u003e is the most represented brand in this category, with four main references: atolls in \u003cmeta charset=\"utf-8\"\u003eStandard versions (600 mm diameter, 200 mm height, 45 liters internal volume, 10 liters storage compartment) and Large versions (700 mm diameter, 230 mm height, 70 liters internal volume, 16 liters storage compartment), available in yellow and red, both complete with inner tube and in shell-only versions.
