The MK25T EVO is machined from a solid block of titanium which will not corrode, even in concentrated saltwater conditions, promising years of trouble-free use. It offers excellent resistance to freezing, superb inhalation sensitivity and instant delivery of air on demand. The new S620 X-Ti embraces the best features of SCUBAPRO's renowned S600 in an upgraded, state-of-the-art design. Smaller and lighter but using the same-sized diaphragm, the S620 X-Ti delivers effortless airflow under all dive conditions. The titanium inlet tube is super-efficient, the large purge button improves water circulation, and the new exhaust tee enhances overall performance.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch5\u003eFeatures\u003c\/h5\u003e\n\u003cdiv\u003e\n\u003cul\u003e\n\u003cli\u003eMachined titanium body is lightweight, highly resistant to
