Featuring a high-contrast backlit display with normal and large-text screen views, it provides clear readings of real-time depth and No-Decompression Limits (NDL). Powered by the Bühlmann ZH-L16C 16-tissue model, it provides audible and vibration alarms to assist underwater dive time and safety stop monitoring without relying on worn rental gear. 【賣點 / Key Features】 - 個人專屬裝備與日誌：自備專屬電腦手錶能建立高度的操作熟練度與安全默契，告別潛店租借手錶按鍵老化與型號混亂的痛點，完整記錄個人考證以來的連續下潛日誌。 / Personal equipment and dive logging. Owning a dedicated dive computer builds operational familiarity, avoids worn or inconsistent rental units, and maintains a continuous log from your very first training dive. - 大字清晰易讀介面：高對比度背光螢幕支援大畫面顯示切換，大字體讓新手在水下緊張或低能見度環境中，一眼即能精確判讀水深、水溫、免減壓時間及 5 米安全停留倒數。 / High-contrast display with large digits. The switchable large-text interface ensures beginners can instantly read depth, temperature, NDL, and 5m safety stops even in low visibility or stressful moments. - 支援進階與高氧訓練：採用 Bühlmann ZH-L16C 16 組織減壓模型，支援 21% 至 56% 單一高氧氣體調節，考獲 OW 後若繼續報讀 AOW 或高氧專長課程無須換錶，流暢銜接進階學習。 / Seamless AOW and Nitrox progression. Powered by the Bühlmann ZH-L16C algorithm supporting 21%–56% Nitrox, fully accommodating your transition from Open Water to Advanced and Nitrox Specialty courses without requiring a hardware upgrade. - 專業教練諮詢支援：MobiDealerHK 創辦人兼具 SDI 水肺潛水教練資格，提供新手選購、手錶操作及設定諮詢，並設有獨立之水肺考證課程諮詢通道。 / Technical consulting by a certified SDI diving instructor.

【產品概覽 / Product Overview】
CREST CR-4 水下電腦腕錶專為準備學潛水、正在考取證照或剛完成 OW / AOW 的休閒水肺潛水員設計。核心採用國際通用的 Bühlmann ZH-L16C 16 組織減壓演算法，能持續追蹤體內餘氮排放 M 值與氧分壓曝露狀態，並具備三段保守度等級（CF1/CF2/CF3）調節功能。手錶在水下提供即時水深、潛水時間、上升速度指示及 5 米安全停留自動倒數，幫助新手建立良好的潛水安全習慣。手錶內建約1000+筆日誌容量，每次出水後可透過藍牙連線 Dive Story App 檢視深度剖面與各項數據，方便考證學員隨時複盤潛水歷程。手冊明確載明本裝置出廠耐壓測試為 100 米（符合 EN 13319 規範），設計用途僅供休閒潛水性質使用，強烈建議休閒空氣潛水不應超過 40 米深度，且嚴禁用於商業或職業潛水。潛水電腦錶演算法為理論模型估算，無法直接測量個人生理即時狀態；潛水員在下潛前必須依實際氣瓶實測數值親自完成設定，並配合備用儀表與潛水計劃保守進行。

The CREST CR-4 is an intuitive wrist computer designed for student divers, newly certified Open Water (OW), and Advanced Open Water (AOW) recreational divers. Powered by the established Bühlmann ZH-L16C 16-tissue algorithm, it monitors nitrogen M-values and oxygen toxicity exposure with three adjustable conservatism levels (CF1/CF2/CF3). It displays real-time depth, bottom time, ascent-rate bars, and an automatic 5m safety-stop timer to help new divers build solid dive-safety habits. Storing approximately 1000+ dive logs, it pairs via Bluetooth with the Dive Story App to review depth profiles and dive metrics upon surfacing. The manual states the device is pressure-tested to 100m (EN 13319 compliant) for recreational use only, with a recommended maximum depth of 40m for air diving, and is strictly prohibited for commercial or industrial diving. Decompression algorithms are mathematical models and cannot account for individual physiological variations; divers must verify actual tank oxygen contents and configure settings before every dive.

【適合對象 / Who Is This For】

  • 剛考獲或正在報讀 OW（Open Water）的新手潛水員：不想每次出海都花錢租用被別人踩過、按鍵生鏽的老舊電腦手錶，想要一隻操作直覺、大字易讀的專屬手錶，在水下建立安心感與穩定默契。 / New divers training for or holding an Open Water certification who want a dedicated, reliable, and intuitive computer with large digits instead of using worn, unfamiliar rental gear.
  • 正在進修 AOW 或休閒水肺愛好者：主要進行 40 米以內的休閒觀光下潛，需要具備單一高氧氣體（Nitrox 21%–56%）調節、上升速度警示與手機 App 自動同步日誌功能，無須因升級課程而重複換錶。 / Recreational scuba divers advancing to AOW who explore within 40m limits and require Nitrox programmability (21%–56%), ascent rate monitoring, and automated smartphone dive logging without needing a hardware upgrade.

【常見問題 / FAQ】

Q：我剛學完 O 仔（初級開放水域），需要一隻潛水電腦錶嗎？用潛水店借的可以嗎？ / I just finished my Open Water course; do I need my own dive computer? Can I just rent one from the dive shop?
A：非常建議自備專屬電腦手錶以確保操作熟練與安全。租借手錶往往型號不一、按鍵老化，新手在水下若不熟悉借來的錶極易因慌亂而忽略安全停留；自備 Crest CR-4 介面直觀大字，出海前由自己親自確認電量、警示與設定，下水安心感完全不同，更能持續累積個人潛水日誌。 / Highly recommended for familiarity, hygiene, and dive safety. Rental computers often feature worn buttons or unfamiliar interfaces, which can confuse critical stops. Having your own CR-4 ensures clear readability, pre-dive configuration control, and consistent personal log accumulation.

Q：如果我之後考進階（AOW）或學高氧潛水，CR-4 還能用嗎？ / Can I still use the CR-4 if I advance to AOW or Nitrox courses?
A：完全足夠應對，無須更換手錶。CR-4 支援 21% 至 56% 的高氧比例調節（涵蓋休閒高氧最常用的 EAN32 與 EAN36）；只要在下潛前親自量度氣瓶並輸入氧濃度數值，手錶就會自動依 Bühlmann 模型重新計算免減壓時間，完全配合進階課程與專長培訓。 / Fully capable without needing a new watch. Supporting Nitrox programmability from 21% up to 56%, the CR-4 easily accommodates standard recreational blends (EAN32/EAN36) for your Advanced Open Water and Specialty training.

Q：每次在海水中使用 CREST CR-4 後，原廠建議的清潔保養步驟是什麼？ / What is the manufacturer-recommended post-dive cleaning procedure after saltwater use?
A：依原廠手冊指示，請將手錶整支浸入清水約三至五分鐘並輕輕晃動以溶解細縫鹽份。請勿在水中大力敲打撞擊、請勿使用強力水柱沖洗、請勿使用清水以外溶劑；清洗後置於陰涼處自然風乾，並確保充電孔完全乾燥後方可充電。 / Soak the watch fully in fresh water for 3 to 5 minutes and shake gently to clear salt deposits per the manual instructions. Do not strike the device, use high-pressure water jets, or apply cleaning solvents. Air dry naturally and ensure the charging port is completely dry before charging.
