The Big Scare (Bat Islands)
深度范围指从潜点顶部到通常最大深度；"建议认证等级"是运营商通常要求的主流机构等级，并非法律规定。水流和能见度每天都会变化，请将这里的所有信息视为规划参考范围。
The Big Scare is Costa Rica's most honest adrenaline dive: no cage, no bait, just bull sharks on their own terms. Divers descend quickly to the sand at 25-30 m off the Bat Islands, settle low with hands folded, and wait while heavy females - some visibly pregnant in season - materialize out of the green-blue and make deliberate, unhurried passes, sometimes close enough to count scars. Guides run the protocol strictly: grouped divers, no reaching, controlled ascents. Between shark passes, devil rays and eagle rays work overhead and big cubera snapper loiter. The season runs roughly May to November, when seas allow the long run north from Playas del Coco.
您此行的高光时刻: Unbaited bull sharks at depth, disciplined small-group protocol, wild northern-corner setting
地形地貌: Volcanic rock and sand flats around the Bat Islands' outer pinnacle
水流: Exposed volcanic rock off the Santa Elena Peninsula; surge and current are part of the package.
入水前须知
危险因素: Depth with short no-deco windows, current and surge, large predators requiring strict compliance with the briefing.
保育: Within Santa Rosa National Park's marine sector; operators carry park permissions and follow encounter rules.
高氧（Nitrox）: 在此值得使用：这些潜点的深度范围内，富氧空气（nitrox）能有效延长免减压停留时间，前提是您已接受相关培训。
