I've only dove a few times and am interested in doing it regularly. Though, this is probably a really expensive hobby.

You guys know of any way I can get certified (Advanced and rescue) for a cheaper price or even paid for? I know that my uni has a bit of a discounted rate but was wondering if there are any other options.

Maybe I can do a little marine surveying volunteering for a free cert idk.

My wife, a dub and I are all certified and I'm starting 2 more kids on certification this winter. I'm looking for an air integrated wrist computer that can monitor multiple wireless units (preferably at least 4). Anybody have any favorites or recommendations?

I found this super interesting!

Anyone have a recommendation of n a good dive shop in Cancun? Looking to do a cenote dive in early January and had looked into Chad Mool cenote but wondered if anyone has had an excellent experience somewhere else?

Pretty new diver here, about 40 dives, and looking for advice.

Just finished up a week of dives in Grenada, and made a point of paying attention to air consumption. Based on Internet advice, I focused on breathing deeply and exhaling completely, counting 4 seconds in, 6 seconds out. Doing this, my computer reported average SAC has dropped from about 0.8 to 0.5, and I'm not the one calling dives for gas anymore. This seems like a great improvement.

However, my buoyancy goes to shit when I'm doing this. Breathing more "normally", I can maintain a neutral depth with good trim. But with this more efficient breath control, I go up and down several feet with every breath. This actually makes it pretty easy to control when I ascend and descend, but obviously isn't great for most of the dive.

If I try to breathe normally-but-slow, I feel like I'm hyperventilating.

So what's the trick here? How do you both breathe efficiently and control your buoyancy?

I think I'm pretty well weighted, s

Seeing any one of these things during a dive would be a highlight of my life. Being able to experience all of it at once puts this at the top of my scuba bucket list. Maybe one day...

My current dive kit:

• XDEEP Ghost Deluxe with both back cargo pockets (one for backup mask, other for SMB+line)
• Apeks XTX50 with DIN DST and yoke converter for travel (at the moment, I’m diving with pretty standard length hoses, but may move to long hose in the future) I use a bungee necklace for my octo, so take a bit of a hybrid approach.
• Shearwater Perdix with AI sensor
• I have an old Oceanic watch dove computer as a backup
• Cressi Digi 2 as an in-line backup to my dive computer as well. I’m not afraid to have my pressure be digital. If that ever breaks, then I may change my mind. It’s nice to have the digital depth as well in case my dive computer ever malfunctions.
• Backup ScubaPro compass
• Fins are not pictured, but currently using Folding Fins. I really like them except the way that the boot holder clips into the ba
