{"title":"Scuba Pressure Gauges (SPGs) – Easy, Reliable Gas Monitoring for Divers","description":"\u003cdiv class=\"sd-faq\"\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3\u003eDo I really need an SPG?\u003c\/h3\u003e\n\u003cp\u003eYes. Your SPG (Submersible Pressure Gauge 潛水壓力錶) shows how much air you have left. Every diver needs one, regardless of experience level.\u003c\/p\u003e\n\u003ch3\u003eWhat bar scale should I choose?\u003c\/h3\u003e\n\u003cp\u003eMost divers in Melbourne use 0–300 bar SPGs because almost all tanks are filled to 200–232 bar. If you are new to diving, this is the safe and standard option.\u003c\/p\u003e\n\u003ch3\u003eWill the SPG fit my regulator?\u003c\/h3\u003e\n\u003cp\u003eAll SPGs we stock use the standard HP (high-pressure) connection. They fit almost every regulator on the market, including rental and student gear.\u003c\/p\u003e\n\u003ch3\u003eWhat is the difference between brass and lightweight SPGs?\u003c\/h3\u003e\n\u003cp\u003eBrass SPGs are heavier and extremely durable. Lightweight SPGs are smaller and ideal for travel. Both work the same — it’s mostly a comfort and preference choice.\u003c\/p\u003e\n\u003ch3\u003eDo I need a glow-in-the-dark or luminous SPG?\u003c\/h3\u003e\n\u003cp\u003eLuminous markings help you read your gauge on low-light shore dives such as Mornington Peninsula or night dives around Black Rock.\u003c\/p\u003e\n\u003ch3\u003eHow often should an SPG be serviced?\u003c\/h3\u003e\n\u003cp\u003eMost divers replace the hose or O-rings every 1–2 years. Bring your SPG into Simple Dive and we can check hose condition and HP swivel safety during your regular servicing.\u003c\/p\u003e\n\u003ch3\u003eCan I replace the SPG hose myself?\u003c\/h3\u003e\n\u003cp\u003eIt’s recommended to have a technician do it to ensure no HP leaks. Incorrect installation can lead to rapid gas loss underwater.\u003c\/p\u003e\n\u003c\/div\u003e","products":[],"url":"https:\/\/www.simpledive.com.au\/collections\/scuba-pressure-gauges-for-divers.oembed","provider":"Simple Dive ","version":"1.0","type":"link"}
