My suggestions for a safer dive with emphasis on the solo freediver
are:
- just prior to surfacing always lean back and then proceed to lay on
your back at the surface. Idea is that if you do BO or LMC there is a
better chance your airway will remain out of the water and you can
maintain floating at the surface safely.
- ensure your snorkel is not in your mouth throughout the whole dive
especially upon surfacing.
- practice and make routine a solid recovery sequence with focus on
breathing and minimal exertion.
- based upon an aggressive dynamic and your breathup sequence for such
a dive, ventilate significantly less, thus inducing nasty CO2 feeling
earlier and it encouraging/forcing yourself to surface early. To have
a longer dive, you have to be more efficient in your technique and
dive style.
- be well hydrated long before the dive.
- reflect on how much activity you participated in for the past two
days prior to the dive and if significant exhaustion occurred overall
or specifically in the legs/torso, limit your dive depth well above an
aggressive recreational dive depth for yourself. This applies as well
if you have recently been sick.
- limit your dive time significantly in reference to your PB dynamic
or aggressive recreational dive. Limit further if you have recently
been sick, exhausted, or dehydrated. Also limit dive time if you begin
shivering.
- attempt to be consistent with regards to your breathup, recovery,
exertion vs. time, pre-dive preparation (ie. diet, body temperature,
hydration, flexibility, metabolic state, etc.).
- do not let yourself overheat. Flush your suit to maintain
temperature.
- take a break, limit dive time and depth, and put extra emphasis on a
solid breathup and relaxation if you undergo a stressful dive due to
circumstances such as panic, narcosis, unforeseen exertion, etc.
- be aware of differences from the normal in your body and adjust your
approach to play it safe.
- always surface with your hands over your head or look up to ensure
you are not going to smash your head into an object.
- always focus on relaxing even if you find concern about your
circumstances. Anxiety will only work against you.
- do not swim underneath things.

將較重的配重 配在後方 若發生昏迷或者因為極度缺氧而失去運動能力 你將會有比較大的可能 仰躺在水面上 提高自救的機率 (我發現配重重的在後方還
又一個好處 那就是腰比較不會酸)

在水下潛水時 請確保你的呼吸管沒有繼續咬著 放開你的呼吸管並且養成習慣 閉著嘴吧 當你因為過度的閉氣而失去運動能力或昏迷時 這可以保護你肺部的
乾燥 禁止海水輕易進入你的呼吸系統 提高生存機率 (放開咬嘴可以放鬆臉部肌肉 增長閉氣的時間喔)

閉氣的時間要自我約束 而每個人的能力都不同 所以請依照你平日練習時最好的閉氣時間來做估計
如果你在水下純粹靜態 沒有動作 那閉氣時間應該是你最佳成績的一半
如果你是緩慢的巡航移動 閉氣時間應該是最佳時間的三分之一
如果你在水下衝刺或者受到驚嚇 請約束自己的閉氣時間為四分之一
假如你下水前的幾天有點生病或者身體狀況比較差 請再保守一點 以利安全

不要讓自己的體溫過高 如果發現太熱 請拉一下領口讓冷海水灌入 調節體溫
過高的體溫將會急速的消耗氧氣 而間接發生危險 並請穿著適當的防寒衣
因為過冷的水溫將容易導致抽筋等意外

巡航時請盡可能將你的手放在你的頭前方 這樣可以確保你的頭不會撞到銳利的岩石 當你在海底往上升時 若對於是否可以清醒回到水面有疑慮時 請將你的手
舉過你的頭 一方面可以使身體姿勢較為流線 更重要的是可以增加腦部的血壓 延後昏迷的發生

不要鑽入洞裡 或者在某一個物體的下方尋遊

注意身體的狀態 按照不同的身體狀態選用適當的呼吸法(這一點必須從平日紮實的練習培養起來) 水面上的呼吸準備改選用什麼樣的方式 完全按照當時的身
體狀態而定 不可勉強 通常而言身體狀態再怎麼好 都不要超呼吸超過五次
