Depth gauges

Four standalone mechanical depth gauges in two size classes: Mini 70m (SKU 513100) and Standard 80m (SKU 513000) in metric scale, plus the imperial equivalents Mini 200ft (SKU 513101) and Standard 230ft (SKU 513001). All use a bourdon-tube mechanism with a maximum-depth indicator needle that records the deepest point of the dive. These are analog instruments for use as standalone depth gauges or as the depth element within a console.

The Standard 80m (SKU 513000) is a full-size depth gauge with a 52mm or larger dial face reading to 80 metres, with a maximum-depth indicator needle that remains at the deepest recorded depth until manually reset by rotating a bezel or using a reset mechanism. The Mini 70m (SKU 513100) uses a compact dial in the same Mini form factor as the Mini 400bar pressure gauge — it is sized for use in Combo 2 mini consoles and as a compact standalone gauge. Imperial equivalents (SKU 513001 and 513101) use feet and feet/metres dual scale dials with identical mechanisms.

What to Look For

  • Standalone depth gauge for divers using a computer as primary. Divers who rely on a dive computer for depth and NDL data carry a depth gauge as a backup — if the computer fails mid-dive, an analog depth gauge allows the diver to track maximum depth for decompression planning purposes during the ascent. The Mini 70m is sufficient for this backup role; the compact form factor stores in a BCD pocket without bulk.
  • Maximum depth indicator for dive planning and logging. The maximum-depth indicator needle records the deepest point reached during the dive and holds that reading until reset. This allows the diver to record maximum depth for the dive log after surfacing even if they did not note it during the dive. Verify the reset mechanism on a new gauge before diving — the needle should hold firmly and reset cleanly without sticking.
  • Standard vs. Mini form factor for console integration. If the depth gauge is to be used in a Combo 2 mini or Combo 3 mini console, the Mini form factor is the correct choice. Standard gauges are incompatible with Mini console housings. Standalone use works with either size; the Standard offers better readability at the cost of slightly greater bulk.
