Pinnacle Diving Company is capable of providing full inspection, maintenance, repair, and modification services for a wide range of diving equipment and Life Support Equipment (LSE), including regulators, BC's, Wetsuits, Drysuits, and more. We have 20+ years of inspection, maintenance, engineering, troubleshooting, testing, and evaluation experience, and if we can get parts, components, and service kits for your equipment, we can take care of it and get you back in the water safely.
Many divers send their regulators, drysuits, and other gear back to the manufacturer for service each year, and they are charged high rates for the servicing and shipping costs. Being an "independent" provider means we can potentially save you money on costs, ultimately making it more affordable for you to maintain the gear you love.

We can service Apeks, EDGE/HOG, DiveRite, and Aqualung regulators any time. We can also service nearly any other manufacturer as well, provided we can get servicing kits and parts for your specific model. From 1st stages to 2nd stages, HP/LP hoses, SPG's, and LPIH's, we can even do custom setups too.
All regulator servicing will be charged ¥15,000 for labor.
All regulator servicing will be charged for the cost of service kits for your model regulator. However, customers my purchase and supply service kits themselves if they want to.
If any parts need to be replaced due to corrosion or damage, we will discuss it with you prior for full transparency.




We can perform repairs and custom modifications on most wetsuits and drysuits, including both neoprene and trilaminate drysuits. We can do hole patches, tear repairs, changing seals and zippers, replacing valves, socks, and boots, and even custom modifications, such as valve relocations and installing ring systems.












All inspections, repairs, and modifications will incur a ¥15,000 labor cost in addition to the cost of parts, expendable items, and disposal / waste charges.
Total costs will depend on item costs (including any shipping required), and extent of work required beyond estimates. Initial costs may be billed up-front, with remainder due at time of pickup / delivery.
PDC can not guarantee timelines for completed work, but will do our best to assure the fastest turn-around times possible.
All drysuits are expected to be clean, both inside and outside, and free of any oder, dirt, or grim prior to acceptance. PDC may charge a cleaning fee for dirty or foul suits, and has the right to refuse service at any time.
