What Silent Diving does

Silent Diving is a privately held, founder-operated exclusive distributor of AP Diving closed-circuit rebreathers (CCRs) and related products for North, South, and Central America. Founded in 2003 and operating for nearly 20 years, the company is led by President and co-founder Mike Fowler (34 years of diving experience, 23 years on the AP Diving Inspiration, former AP Diving employee) and Operations Manager Jennifer Jennings (27 years diving, 2,000+ hours on the Inspiration, MBA). The company maintains offices in Port St. Lucie, Florida (US) and Brockville, Ontario (Canada), neither open to the public.

The core product portfolio centers on the AP Inspiration and Evolution CCR systems — configurable units from recreational through Trimix specifications featuring dual oxygen controllers for ppO2 monitoring, CO2 scrubber systems, Automatic Diluent Valves, configurable counter lung placement (OTS or BMCL), and software-upgradeable architecture. The 2020 Color Vision Display upgrade added an ultra-bright IPS full-color screen with integrated compass and Bluetooth PC connectivity. Beyond the rebreathers themselves, the catalog spans consumables (APD14/APD16 oxygen sensors, Sofnolime 797, lithium batteries), replacement parts (cylinders, DIN valves, service kits), dive computers (Garmin Descent, Shearwater Nerd 2/Perdix 2 Ti/Petrel 3), DPVs (BlackTip, Lefeet), dive lights, and a suite of hardware upgrades (ADV, BMCL, CO2 sensor, OCB bailout mouthpiece, 2020 Vision display).

The business model is direct-to-consumer e-commerce and direct sales, with personalized phone-based consultation guiding customers through configuration and ordering. Revenue streams are hardware sales (rebreathers, accessories, parts, upgrades) and professional services (in-house scheduled maintenance, repairs, and authorized servicing with electronics routed back to AP Diving's UK facility). Complementary partnerships with Analox, Dive Xtras, O'Three, and Kraken extend the AP Diving ecosystem. There are no disclosed funding rounds, no external institutional investment, and no headcount data — the company appears bootstrapped and run by its two principals. The market is a small, technically demanding niche of technical and advanced recreational divers across the Americas.
