Apeks DB4 First Stage for Apeks XL4 REVIEW

Apeks DB4 First Stage for XL4: https://www.deepbluedive.com/brands/a... The Apeks DB4 is a high-performing, lightweight, cold water ready 1st stage. Designed as a workhorse of UK diving it can handle extreme environments anywhere in the world. Featuring a tough over-moulded end cap and environmentally sealed diaphragm, the DB4 is nearly impervious to ice build-up. You don’t need to worry about your air supply freezing open in ice-cold water letting you focus the stuff that matters: enjoying your dive. This robust design also protects your DB4 from impact damage or wear. The heat exchanger diaphragm clamp’s large surface area increases the gas temperature within the first stage. This improves the cold water performance of the DB4 and helps warm the air up before being routed to your 2nd stage for breathing. The DB4 features an overbalanced diaphragm design. When you descend the water pressure build-up around you impedes the flow of air to your second stage, making breathing difficult. This design compensates for that ensuring you receive clear, consistent flow of air throughout your dive no matter how deep you go.
