Can get anyone that you feel is stylish and within your budget. They are somewhat similar. Just make sure its 3mm thick.

You practice skills in pool with your instructor during your open water course. He will guide you on multiple skills to do and complete. Of course the pool will be at least 2 meters at the deepest end.

Which dive center you are taking your course with? Going to which island? Have fun and enjoy the course!

if you get cold easily like me and have a little budget to splurge and do intend to make this a long term hobby id recommend the proteus 2 from fourth element x.D

Comfort, price, your legs muscles.
Oh fin size is also important because if you travel your bag needs to fit the fins

for open heels you should try the dive boots first, then the fin to see if it fits comfortably without muscle or squeeze cramping due to the foot pocket being small. that being said both should be purchased at the same time so that you can try them.

whats your shoe size? i have a spare pair of relatively new fins which im looking to let go as well (look up the mares x-stream fins)

Here you go

You from klang valley area ? Try check with other dive center, as I know suunto having big discount now, this price is kinda high than last time when I purchase with gst.

Have you tried the wetsuits that you've seen in the fitting room? What do you think so far?

seen and heard but have not tried, its not a common brand in asia, at least in japan or malaysia for my case, some brands are mostly sold in the US or EU region, although im a sucker for nice design and symetry but i try to avoid color because not every brand has the same color palette for a design i like....

if you cant or are unable to try because the local shops dont sell them you should try to read more reviews about it, although some less common brands has lesser reviews so opinions can be biased. personally you should set your expectation with budget first and compare prices across online stores and local stores which carry the brand to get the average pricing since i do know for example scubapro in malaysia is overpriced because of monopoly by sealantis

so far i havent seen any brands with a similar product in the neoprene category to fourth element especially the proteus 2 which i am using, since as mentioned the inside is fleece

y wishlist as well if in the future i want to try other brands 

i dont know much about singapore, but a quick search for the W3 shows 2 shops you can check, one is Waikiki DC and scubawarehouse SG branch, personally i think its much more expensive in singapore

Practice hovering.
When you do your safety stop make sure to deflate your bcd slowly as you go up. Watch your depth gauge or dive computer to know where to stop to hover.
Most situation like this happens when divers got their weighting wrong or didnt properly deflate their bcd. New divers find it difficult because they breath in too much due to nervousness.

Using Suunto d4i. No regrets so far. Looks good enough if u want to use it for daily wear too
