Dive computers are accurate to within one or two feet, however capillary gauges measure depth as "close enough".  Alec shows the evolution of capillary depth gauges using Boyle's Law of pressure and volume.

*** In this episode of Vintage Scuba ***  
- a 1953 US Divers square plastic capillary gauge
- a late 1950's "Bath-O-Meter"
- how to clean a capillary depth gauge
- Dacor LCG Professional Model depth gauge to 250 feet
- the first dial gauges used bourdon tubes but still had a backup capillary gauge around the dial
