    Tanks?

    In the process of purchasing my equipment and had a question on tanks. Its seems that if I was to rent any piece of equipment , a tank would be it. Is it better to buy or rent?. I'm sure all tanks that are rented are inspected on a regular basis,,, right?

    Yes,
    Purchasing tanks is a convenience because one is not dependant on the shop being open to pick-up or return. I got certified at college, so I had little money. I rented for about 6 months until they had a sale on tanks during the summer. You have to determine how often you go and how easy it is to get a tank from the dive shop. I got aluminum tanks (cheaper) initially then upgraded to steel (could not afford during college). My tanks must have a visual inspection every year and hydo every 5 years, plus the cost of the fill. The rental includes everything for the first fill.

    only a few reasons to purchase tanks.

    1.) You dive enough to justify the cost of the tank and savings over rented tanks. (don't forget to include your airfills in that math along with visuals and hydros).

    2.) Convience. - this is the real reason most people own tanks. They don't want to hassle with a 2nd trip to the dive shop to return it, or to have to bust-ass to get there before they close the night before a dive to rent one or return it within the allotted time.

    Convience also allows you to go get them filled on your schedule.

    Also with gas prices being as high as they are, not having to make a 2nd trip to the LDS to return a rented tank helps offset the cost of ownership. Consider time in that equation also. (which equates to convience).

    Another convient thing about owning is that you don't have to go to the LDS an hour or so early to pick up tanks before a boat dive and have to wait in line at 7am or 6:30am because of it.

    3.) The other main reason people own their own tanks is that they want a specific tank. For example a LP108 or a HP100 steel tank. Or they want a set of doubles. Or they want certain valves, such as DIN. most shops don't have these tanks in their "rental fleet", or if they do, the choices are very limited.



    If you're a "vacation diver" and typically use AL80 tanks, then purchasing tanks might not be the best idea for you. it's hard to take tanks with you on vacation as you load up a weeks worth of suitcases for the kids, condo stuff, dive gear, etc... not much room left for the tanks in the car. owning tanks might not be for you especially if you fly to your dive destination for your "vacation dives".

    Depends on how often yuo use it LOCALLY. You don't want to drag them with you.

    If you think you will be diving locally a lot, the tanks will pay off soon compared to renting. I am getting tanks these days too - I'm just waiting for a good used tank deal to pick them up.

    Joe, I would wait until you know how often you will be diving. When you dive will it be 2 cylinders per day or just one? Once you have this number you can do some simple math.

    Let's use a figure of 12 local dives per year.
    Rental $10-$15 per cylinder = $100 - $150 per year.

    Purchase $150 per cylinder. $15 per year for VIP. $5 per air fill. $6 per year hydro expenses (needs to be done every 5 years).

    The first year it will cost you (cylinder, fills and prorated hydro) 150 + 60 + 6 = $216
    The second year is when you start to see some savings (VIP + Fills + Hydro) 15 + 60 + 6 = $81

    If you will be doing 2 tank dives (charter?) you will need 2 cylinders.

    Another thing to look at is if you will be travelling to dive. Unless you are driving to the dive destination, it is impractical to take your own cylinders. you will be renting when you get there.

    The moral of the story is...You probably should not buy cylinders until you have been in the sport for a couple of years and can weight the benefits vs cost.

    I figured it out like this:

    I live relatively near the beach but about an hour from my LDS. Factoring in gas to and from the dive store the night before to get the tanks, then to return them after the dive, it was costing me a bunch (in time as well) to do a shore dive. $6 bucks there and $6 bucks back, so 24 dollars total round trip in addition to the rental fee (Did not include the fill). So it cost me about $36 dollars more for 2 rental tanks. I got two HP steel 80's (there are much less expensive tanks out there) for $500 from ST. 500/36 = 13.8 or 14 dives to make up the cost. This doesn't include any dives I may cancel after getting the tank and not being able to use it (sometimes the surf is just too rough). My wife goes past the LDS once a week anyway (Tuesdays) so she drops off the tanks to get filled and picks them up on the way back.

    I would say a tank is the last thing to get, but after you get all your other equipment, take a look at the numbers involved and figure out what tanks you want and how many dives it will take to make it up.

    Hey Joe L

    I'm new to the forum but I'll give you my opinion.
    It depends on the type of diving your going to do, if ocean diving is your thing then renting is fine though the price is really going up, (you may find that you will recoup the cost of Aluminum tanks in a short time if you dive a lot (50 to 100 times a year) on the other hand if you own tanks you can control how they're maintained and who fills them ( controlling the quality of the air that goes in them ) Then you need to decide steel or Aluminum. The Aluminum is cheaper and the steel will help eliminate some wait from you belt or BC if weight integrated. Then with steel you have high pressure or Low pressure, most steels are going to high pressure now just make sure if buying high pressure you leave them at the dive shop to fill so they can top them off after the cool a little or you'll end up with a short fill I personally own 4 tanks. Hope this helps

    Great example. Although, I think you can get away with cheaper tanks thank $150. Depending on the area you are in, I've seen 2 AL80s to go for $100 at craigslist (without current vis or hydro)

    This is the practical side of the story.

    The real side of the story of owning tanks is convience. that outweighs the extra yearly cost.


    But... if you factor in gas and time of having to pick up and return rental tanks on a "tight schedule" (when they are due), then that greatly offsets your cost.

    Especially when I might have to drive 20 minutes to return a rental tank. With gas being $4/gallon and driving that big SUV, it sure is nice not making repetitive trips that aren't needed.

    I dive a good bit (80-100 dives per year pace); I always drive to my destination; and charters on the NC coast do not include tanks. At half the cost of renting and much more convenience buying was a no-brainer for me. My tank costs are now running about $2.50 per dive.
