The H-Plate Mk III

My design single-tank SCUBA backplate in 3mm 316 Stainless Steel.

Finished dimensions: Length 390mm, Width 238mm, weight 2.24kg (5 lbs).

A full size SCUBA backplate optimised for, and dedicated to, single tank use, forming the most stable, lowest profile platform for DIR single tank diving.



Tank profile of the H-Plate Mk III (on left) compared to a Halcyon backplate with Highland single tank adapter (on right). For both of these, the backplate is flat against the floor, and both are using Oxycheq single tank wings with identical centre sections.

The Halcyon/Highland combo is not particularly high-profile compared to some other combinations available, however the H-Plate still places the tank about one inch (24mm) closer to your back.

My other backplate designs:

  • The original H-Plate (2003)
  • H-Plate Mk II (2007)
  • Aluminium twinset backplate (2008)
  • Stainless steel twinset backplate (2009)
