The inhalation-effort knob can be adjusted to change the amount of effort required to initiate airflow, while the coaxial VIVA dive\/pre-dive lever controls Venturi assistance. Together, these controls allow the regulator to be tuned for comfortable breathing underwater while helping reduce unwanted free flow when the regulator is not being used.\n\u003c\/p\u003e\n\n\u003ch3\u003eCompact \u0026amp; Travel-Friendly Design\u003c\/h3\u003e\n\n\u003cp\u003e\nThe C370 uses a compact reinforced technopolymer casing to reduce size and weight without giving up diver-adjustable controls.

Its air-balanced design, inhalation-effort control, adjustable VIVA, lightweight casing, and Hi-Flow mouthpiece give it the features expected from a full-performance primary regulator while keeping the overall package small and travel friendly. The redesigned interchangeable frame system also makes it easy to personalize or identify your regulator without changing the second stage itself.\n\u003c\/p\u003e\n\n\u003c\/div\u003e","brand":"Scubapro","offers":[{"title":"Graphite","offer_id":67644919513302,"sku":"REG494 GRY","price":380.0,"currency_code":"USD","in_stock":true},{"title":"White","offer_id":67644919546070,"sku":"REG494 WHT","price":380.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0551\/8839\/0071\/files\/scubapro-c370-2026-second-stage-regulator-graphite-gray.webp?v=1792185668","url":"https:\/\/www.houseofscuba.com\/products\/scubapro-c370-second-stage-regulator-2026","provider":"House of Scuba","version":"1.0","type":"link"}
