使用高氧潜水的好处：
1减少体内氮气含量，
2降低减压病产生
3有更多滞底时间
4潜水后疲劳感降低，每天可以潜得更多。
使用高氧潜水是一门进阶的专长,必须学习才能取得使用高氧的资格，EANX潜水并不能让你潜的更深更久,对EANX潜水不了解，茂然使用反而更增加危险，您要是对EANX潜水有兴趣,应向你的教练或具有高氧资格的教练询问

BOXFISH，建议你学到对水没有恐惧感就可以了，其实我自己是PADI的DIVE MASTER，根据PADI Open Water Diver 课程，应该是理论15课时 潜水技巧31个课时 开放式水域4次装备潜水/分2天进行 （建议1次浮潜） ，这是针对所有学员的标准，也就是说，如果你的培训中心或教练遵循以上所规定的课时数完全没有偷工减料的话，你考试时不及格，那就是你学得不好，否则，你有权向培训中心或教练提出质疑，又或者可以向PADI总部投诉。

我在水下深呼吸到胸腔感到微微不适，有问题吗？我自己觉得我呼气太快。
应该只是压力的问题。不要杯弓蛇影。 |

既然各位老大都没反映，可能系统不同的关系，就我来回答你的问题，其实课程顺序不重要，一般学习的顺序是理论-徒手-装备-开放水域，但我认为你的教练非常没有职业道德，其实考试的内容都包含在学习的范围里面，也就是说你水面漂浮10分钟不过关而导致你拿不到OW的资格，应该在训练过程里教练专门为你这个弱项给你训练的时间和教你技巧，教练教练，意思就是教你练习嘛，事实上水面漂浮10分钟无要求一定要什么姿势的，我们小时候玩的浮冬瓜也可以的............所以真是为你感到不值，潜水那么多年，潜友认识不下七、八十，我还是第一次听到水面漂浮10分钟不过关而导致你拿不到OW的资格。你的这个教练明摆着就是坑人。

“Scuba Diver，不是OWD？”你考的是NAUI还是PADI的？如果你考PADI OW 而因为没有通过十分钟的Floating拿了Scuba Diver的证，那就太冤了，那意味着你还是要回到那里再补考一次，我有个朋友也是不听我说，说是将就假期，跑到澳洲学OW，谁知道时间不够，还差3个DIVE没有出海，拿了Scuba Diver的证，回来后没有PADI的教练肯接手，所以又花了冤枉钱在别的教练处补考，哈哈
没有通过十分钟的Floating？你在哪里考的？讲来让大家知道一下.........

轻松流畅上网你是否注意到你的电脑系统磁盘的可用空间正在一天天在减少呢？是不是像老去的猴王一样动作一天比一天迟缓呢？
没错！在Windows在安装和使用过程中都会产生相当多的垃圾文件，包括临时文件（如：*.tmp、*._mp）日志文件（*.log）、临时帮助文件（*.gid）、磁盘检查文件（*.chk）、临时备份文件（如：*.old、*.bak）以及其他临时文件。特别是如果一段时间不清理IE的临时文件夹“Temporary Internet Files”，其中的缓存文件有时会占用上百MB的磁盘空间。这些LJ文件不仅仅浪费了宝贵的磁盘空间，严重时还会使系统运行慢如蜗牛。这点相信你肯定忍受不了吧！所以应及时清理系统的LJ文件的淤塞，保持系统的“苗条”身材，轻松流畅上网！朋友来吧，现在就让我们一起来快速清除系统垃圾吧！！
下面是步骤很简单就两步！
在桌面上点鼠标右键，选择新建一个“记事本”，把下面的字复制进去，点“另存为”，把文件名定为“清除系统LJ.bat”就完成，记住后缀名一定要是.bat，好ok了！你的垃圾清除器就这样制作成功了！双击它就能很快地清理垃圾文件，大约一分钟不到。
@echo off
echo 正在清除系统垃圾文件，请稍等......

echo. & pause
以后只要双击运行该文件，当屏幕提示“清除系统LJ完成！就还你一个“苗条”的系统了！！到时候再看看你的电脑，是不是急速如飞呢？可别忘了回帖喔！
注：LJ就是垃圾的意思！这招比那些所谓的优化大师好用！不会破坏系统文件！

至于潜点嘛，看这里：
1. Lion's Head

Average visibility : 20 - 25 meters, but visibility may reach up to 40 meters
Depth of reef : Average 15 - 20 meters. Maximum: 30 meters
Type of dive : Wall drift dive
"Lion's Head" is a protected marine park situated in a channel. Subject to strong currents, this deep wall reef boasts many exciting overhangs and forms the perfect environment for a large variety of fish, ranging from small basslets, red tooth triggers and fusiliers to the larger pelagic species such as tunas, napoleon wrasses, sharks and turtles. You will encounter beautiful nudibranchs on the underside of the overhangs, magnificent sponges and some very pretty hard and soft corals covering the reef.
2. Kuda Haa

Distance from Vabbinfaru : 45 minutes
Best time to dive : All year round
Average visibility : 20 - 25 meters

"Kudu" is a protected marine sanctuary shaped like a two-humped camel's back. Rising from 35 meters below the sea to six, this beautiful reef is covered in sponges and corals. The abundance of fish living here simply takes your breath away. Large schools of blue-striped snapper roam the deep; clouds of basslets, fusiliers and butterfly fish swim all over, while sharks hover in the shallow areas. You might also come across moray eels, cleaner shrimp and the rare scorpion and leaf fish. This is truly a dive you shouldn't miss when visiting the Maldives.
3. Girifushi Thila
Location : South East North Male Atoll
Distance from Vabbinfaru : One hour
Best time to dive : All year round during high and low tide
Average visibility : 20 - 30 meters
Depth of reef : 10 - 40 meters
Type of dive : Thila dive
"Girifushi Thila" is one of the best known and most beautiful dive sites on this island nation. Sandwiched between two outer atoll islands, strong currents are a permanent feature making diving here very exciting, while providing plenty of nutrients for both corals and fish. This protected reef enjoys overhangs, caves and crevices rising from 30 meters below the sea to ten at the top.
Most of the reef is completely covered in yellow, blue and orange soft hanging corals, as well as stunning sea fans. The current attracts an astonishing variety of small reef fish and large pelagic species such as gray reef sharks, eagle rays, tunas and barracudas. To really enjoy this dive you will need to be a confident and experienced diver.
4. Middle Point
Location : South East North Male Atoll
Distance from Vabbinfaru : One hour
Best time to dive : All year round on incoming current
Average visibility : 20 - 40 meters
Depth of reef : 10 - 50+ meters
Type of dive : Drift dive
"Middle Point" is situated in the middle of the Tamburudhu channel and offers a drift dive for the experienced and adventurous. It rises from 100 meters below the sea to ten. When commencing your dive you will jump into the deep blue of the ocean with nothing much around you until the current takes you to the front point of the reef, where you will observe a large school of gray reef, silver tip and white tip sharks circling the deeper waters. Looking up at the surface you will discover eagle rays dancing in the current accompanied by tunas and barracudas. After some time of underwater dreaming, you can let the current carry you along the reef and enjoy the other treasures it has to offer.
5. Nassimo Thila
Location : South East North Male Atoll
Distance from Vabbinfaru : One hour
Best time to dive : All year round
Average visibility : 20 - 30 meters
Depth of reef : 10 - 35 meters
Type of dive : Thila dive
This dive takes place in the spectacular Bodu Kalki channel. "Nassimo Thila" is a large reef with imposing reef pillars standing proudly at a height of 40 meters. You will wind in and out of this bizarre underwater landscape taking in its amazing beauty. The pillars are covered in blue, yellow, red and orange soft corals and large gorgonian fans. The large overhangs of the main reef also house hundreds of different coral species, colorful sponges and thousands of fish. Large tunas, barracudas and trevallies are often found chasing small reef fish like basslets, surgeon and butterfly fish, as well as entire schools of fusiliers. Turtles and friendly napoleon wrasses can be seen here regularly too.
6. Okobe Thila
Location : Inner South East North Male Atoll
Distance from Vabbinfaru : 40 minutes
Best time to dive : All year round
Average visibility : 15 - 30 meters
Depth of reef : 10 - 35 meters
Type of dive : Thila dive
The "Okobe" marine reserve is one of the most awe-inspiring dive sites in the Maldives, a small thila consisting of three large rock formations. A mooring line is attached to the front of your dhoni (Maldivian word for boat) for this dive. Once you reach the bottom of the line, you will be met by a friendly and curious napoleon wrasse welcoming you to his "home". Further down, it gets difficult to see the reef, as you are surrounded by hundreds of fish. If you believe you are in an aquarium, you will be forgiven. The reef is not large but requires more than one dive if you want to take in all the beautiful corals and fish. A "must see" dive in the North Male Atoll.
7. Rasfari
Location : Outer West North Male Atoll
Distance from Vabbinfaru : One hour
Best time to dive : All year round
Average visibility : 15 - 30 meters
Depth of reef : 8 - 40 meters
Type of dive : Deep dive
"Rasfari" is a spectacular outer reef in the North Male Atoll. Its large sloping wall falls from ten meters below the sea to 25, levels out and then ledges off again dropping down to 90 meters. You will follow the sloping wall some 30 meters down to the reef and marvel at gray reef sharks, silver tip and white tip reef sharks circling right in front of you, while a large family of eagle rays dances in the current. Completing this magnificent show of underwater magic are some giant barracudas, tunas and napoleon wrasses, as well as schools of fusiliers, blue-striped snappers and surgeonfish.
8. Sunlight Thila
Location : Inner South East North Male Atoll
Distance from Vabbinfaru : 40 minutes
Best time to dive : March to October
Average visibility : 10 - 15 meters
Depth of reef : 5 - 17 meters
Type of dive : Manta dive
"Sunlight Thila" is a formation of two small reefs that attract giant manta rays between March and October, when the winds from the south carry a large amount of plankton to this area. Between the reefs lies a 70-meter long sand bottom boasting small coral formations with plenty of cleaner wrasses. During your dive you will kneel on the sand whilst watching these majestic mantas circling above you waiting for their turn to be cleaned. As it is not uncommon to see ten or more manta rays at a time, this dive has become a big attraction for both beginners and experienced divers.
9. Banana Reef
Location : Inner South East North Male Atoll
Distance from Vabbinfaru : 45 minutes
Best time to dive : All year round
Average visibility : 20 - 35 meters
Depth of reef : 5 - 40 meters
Type of dive : Wall drift dive
"Banana Reef" is a very well known dive site in the Maldives - one of the first, one of the best and one of the more treacherous due to strong currents. On the eastern side of the banana-shaped reef, some rocks have broken away and created a perfect habitat for a surprising variety of schooling reef fish and large pelagic. Amongst the large overhangs resides an enormous school of blue-striped snapper. As you carry on along this banana-shaped dive, you will discover a pristine reef wall bursting with life, from different species of moray eels to fascinating corals and fish.
10. Maldives Victory
Location : Western side of Hulhule Airport Island
Distance from Vabbinfaru : One hour
Best time to dive : All year round. Due to strong currents, high or low tides are best
Average visibility : 15 - 25 meters
Depth of reef : 12 - 35 meters
Type of dive : Wreck dive
The "Maldives Victory" is a 110-meter long cargo vessel that sank in February 1981. Our dive takes you 12 meters down a rope to the ship's main deck, where you will be sheltered from the strong currents. Here you will be amazed by the colorful marine life that calls the Maldives Victory home, from large groupers and tunas to giant trevallies and schools of fusiliers. Come face to face with turtles guarding the bow of the vessel and its stunning corals, or step back in time and explore the ship's former accommodation quarters and bridge. On your ascent you will have a majestic bird's eye view of this beautiful vessel. This dive is best undertaken by experienced divers only.

以著名的Banyantree Resort为例，自带装备的潜水员的船潜，视乎潜点的远近，有65-90美元/dive.
课程方面：PADI Open Water Diver时间需要4-5天，包课本、证照费用、Diploma + Log Book=Price: US$ 640X7.8=RMB4992。哈哈，不要惊奇，因为Banyantree 是豪客住的，仅供参考而已，相对泰国、菲律宾、马拉，甚至国内学习Open Water 课程真是天价啊，不过由此证明，马尔代夫学习潜水代价不小啊。

我是想先在浅水的地方玩玩,有熟悉潜水的朋友带着,中毒深了再去考.
路过的........多事问一句，阁下这位潜水的朋友是否有领袖级潜水资格呢？因为带没有经过培训的人潜水是要以上资历的喔。 |
