Hollis DC7 / 500SE

$899.00 $1,050.00


A worthy combination that makes a great regulator: the Hollis DC7 first stage together with the 500SE second stage. The 500SE, which uses a servo controlled valve to provide precision airflow and unparalleled performance, perfectly complements the over-balanced diaphragm of the DC7.

With 2 high pressure and 4 low pressure ports, you can achieve your personal optimum hose routing for either back-mounted or sidemount systems.

Regardless of depth and remaining tank pressure, this reg combo delivers a great performance. The environmental seal further prevents internal corrosion, contaminants, and icing of the first stage. This way the Hollis DC7/500SE regulator set is also suitable for cold water diving!


  • High performance over-balanced first stage
  • 2 HP and 4 LP ports
  • Environmental seal
  • Pneumatically balanced servo valve system
