Stormvogel has an unmanned outdoor fill station at Duikschool Oostvoorne, and nearby services may offer rental, repairs or specialty gas by prior arrangement. Confirm the exact gases, cylinder fittings, payment method and fill eligibility before travel. Flying divers should reserve sports baggage and follow airline and security rules for cylinders, which normally require complete depressurization and may require the valve to be removed. Renting cylinders and weights locally is usually simpler. Bring spares for drysuit seals, low-pressure inflator fittings, lights and cold-water regulators because the lake is not a resort campus with guaranteed stock at every entry.
