Equipment service / Repair
About our equipment services
Southern Maryland Divers takes equipment service and maintenance seriously. Many diving accidents and "close calls" are due to a lack of quality, routine maintenance and proper equipment care. Generally speaking, your gear should be inspected yearly or every 100 dives by a trained technician. Many manufacturers suggest yearly rebuilds, replacing most of the moving parts.
We service ALL makes and models of regulators and BCDs.

First Stage - $45.00 labor plus parts
Second Stage - $35.00 labor plus parts
Octopus Second Stage - $35.00 labor plus parts
Integrated Octopus - $35.00 labor plus parts

Typical turnaround time is 20-30 business days (excludes weekends and Holidays). We strive to have them done as quick as possible, and most are turned around quicker.
With the current state of supply chain issues, there is a chance your service may take longer if parts are on backorder. Please get your gear in for service as soon as possible before an upcoming trip to avoid any delays.
Front of line service is for those that come in right before vacation or service is needed. Although we cannot guarantee it will be done in time due to the condition of your regulator set or necessary parts, this does put your regulator repair at the front of the line. If repair is not completed in time for your trip, a rental set will be issued for your trip free of charge.
Tank and valve services
Tank and valve services we offer
Scuba tanks need a Visual Inspection every year and a Hydrostatic test every 5 years. Southern Maryland Divers can handle all of your tank inspection and cleaning needs. With a quick turnaround time, you will not be without your tanks for long. If needed, rental tanks are issued free of charge when your tanks are with us for service.
Southern Maryland Divers has a PSI/PCI certified cylinder inspector on staff to meet these needs. You can see his credentials at the links below.

Premium gas fills - Air / nitrox / trimix / oxygen
Premium Gas Fills
Clean, pure, accurate gas fills are guaranteed at Southern Maryland Divers. The key to what we do is not just an obsession with preventive maintenance and accuracy, but also the personal attention that your fills get from our blenders. All of our blending, from nitrox to trimix is performed by Gas Blender instructors.
Save Money!
Unlike other dive shops, for our technical fills and upon request, we take the time to analyze the gas that is left in your tank when you bring it in for a fill. We then use extremely accurate computer software to find out what we need to add or subtract to get you the fill you want. This enables us to add ONLY the amount of gas needed to "blend" your current gas to the new mix, saving you money on every fill! Nitrox fills have a max cap of $16.00 per fill up to 40% EAN.
Purity is important!
We use only the purest gas, from medical grade oxygen, to 99.99% pure helium, your'e sure to get the best air available. Our Mako 11 cubic ft / min, K14 compressor is meticulously maintained, following all manufacturer recommended maintenance schedules. We utilize Lawrence Factor high quality filtration to ensure OCA Grade E "hyper pure" air. We sample and analyze our air using Trace Analytics on a quarterly basis to make sure we are maintaining the highest quality gas. Click HERE to see our latest test results, or check it out in person, we have it hung on the wall next to the compressor!
Timely / Accurate Fills
We understand that your time is important, and being up all night waiting for your tanks to be filled can lead to a tired diver the next day. That's why we work hard to get your fills completed quickly. Air fills are usually same day and nitrox fills are usually two day turnaround. When you ask for 32%, you get 32%! We know divers want the fill they request, so we double check our fills and ensure you get what you want.
Nitrox Blending
We use the Nitrox Stik to blend each individual tank to your specification. This means you have less wait, and more accurate results. This also removes a lot of the hazards involved with partial pressure filling procedures. We can dial in your exact mix from 22% to 40% and if you bring us a partially filled tank, we can custom blend it to what you want without dumping your old mix.

***All tanks being used for mixes above 40% in oxygen content MUST be cleaned, certified, and current for oxygen service. It is at the sole discretion of the blender if they wish to accept another agencies oxygen service qualification of the tank. If external visual inspection reveals contamination that concerns the filler, they may require re-cleaning prior to filling the tank. These restrictions are in place for the safety of our blenders and our customers***
