Scuba Cylinders: Get INFORMED
Unless you are freediving, you'll have a hard time spending hours underwater without one of these metal cylinders. Cylinders come in a variety of sizes and materials to allow you to select the best equipment for your dive. Typically, cylinders are made from either Aluminum or Steel and are based on volume-- More volume = More Gas. Simple. There are carbon-fiber cylinders in use, but these are best served for rebreathers (CCR) and Self Controlled Breathing Apparatus (SCBA) used by firefighters, military, etc.
Steel Cylinders
Extremely durable and will easily last for decades as long as they are properly cared for. Steel is a denser metal than aluminum, and will typically have better buoyancy characteristics than aluminum cylinders. However, if you find yourself overweight (speaking to you warm water divers), you may find aluminum to be a better fit. Faber’s Cylinders are appreciated worldwide by scuba divers who choose steel tanks for their aqua-lung apparatus. To give you the lightest (and hence an optimum wall thickness) steel tanks (cylinders) with an ideal buoyancy, Faber’s scuba diving cylinders are diligently manufactured using high-quality steel plates. If you are already using steel cylinders when diving you don't need to be convinced about the advantages of steel. Besides the buoyancy attractions, it occupies a far lower volume for the same water capacity allowing you to enjoy greater space and freedom and free from any worries of developing any premature defects such as sustained load cracking (SLC) found in some aluminum-alloy cylinders such as those from alloys AA6351, AA6082.
Aluminum Tanks
Aluminum cylinders store gases for a wide variety of applications including ultra-high purity gases for electronics manufacturing, specialty and calibration gas, industrial gas, medical oxygen, food, and beverage grade CO2, SCUBA, fire & rescue, alternative fuel, and aerospace. They are the most economical means for dive operators as the cost of the cylinder is typically 40% less expensive--which is why you see aluminum 80cuft/11.1L cylinders in almost every destination around the world.
As mentioned above, aluminum is less dense than steel and does require a little more precaution when caring for them. They will still easily last for more than 20 years with proper visual inspections and hydro-static inspections. One thing to note is that all-aluminum cylinders, except for ones stamped with an “N,” are positively buoyant at the end of a dive. The “N” on some cylinders means they are ‘neutrally buoyant.’
In Technical, Cave, Self-Reliant [Solo] diving, aluminum cylinders are the go-to standard for stages, decompression cylinders, and other high oxygen mixtures. They are typically lighter than steel cylinders and are preferred when a person can’t handle the extra weight on their body. However, that comes at a cost in terms of volume as the lighter the cylinder, the less volume it can [generally] take.

X-Deep NX Aluminum Backplate
Great plate, and great service from Maddie. She had us fitted with new webbing an all clip offs in 15min.

NX Series Backplate with Standard (DIR) Harness
Travel bag
So far the bag is great. Good zipper. Holds my fins , bcd , regs ,masks , wetsuit ,computer ,save a dive kit perfectly . There is no extra room. Pack strategically . Complies with size requirements and fits in overhead compartment on planes easily. My equipment in the bag weighed in at 24 lps. Carries as a back pack or as a duffle bag. Comfortable straps. Holds water inside without any water leaking out when you have to load wet equipment in it and travel inside vehicles after diving to return to hotel ect . I cant say about its durability , this is my first trip with it from Florida to Mexico for several dives. I hope it holds up and lasts for several years. I would definitely recommend one if you fly and dive.

Hellacious Bag
I was skeptical. So I stuffed a paper towel into this bag, crammed the bag into a small pocket and took it to 43 feet while on a 2 hour drive. The paper towel was Absolutely dry at the end. So, I shoved an extra phone AT&T sent me, for no apparent reason, into this bag. The phone worked through this bag as it unlocked with facial recognition.
I beach dive a mile from shore with a DPV and no surface support- Solo. So, basically the Nautilus rescue beacon and my Garmin inReach mini are just there as "two is one and one is none. Not sure what three is. But now I do have three ways for coms due to this damn fine bag.

deep6 eddy SM black
light & stiff was the reason for my choice. Precise positioning is possible with this fin. Power, the other reason for my choice, is yet to be tested against stronger currency as blades are small. To an instructor, this fin is better than quattro as you can back and helicopter kick better. Requires slightly different kicking as well compared with quattro.

Cool breeze
Great dive boots. Cool looking kicks. Regardless of walking on loose rock and gravel gravel beaches , hot pavement, sand , walking on a boat deck they offer great protection and comfort. I like the laces over zippers because i live and dive off sand beaches and i dont have to fight sand in the zippers being stuck

Any Regulator I want
I have been blessed enough to be able to dive any regulator I want.
No regulator breathes better than an Atomic!
It is just a wee bit heavier than the pure titanium but with all the features and offers greater value.
It looks good and is everything I could ever desire in a regulator.
