What Should I Check Before Each Dive? (Pre-Dive Inspection Checklist)

Quick Answer

Pre-dive checklist: 1) Inspect O-rings for damage, 2) Verify connector cleanliness, 3) Check mating surfaces, 4) Confirm locking mechanism, 5) Test electrical continuity. 5-minute inspection prevents costly failures.

Pre-Dive Inspection Checklist

Visual Inspection (2 minutes)

  • □ O-rings present and undamaged
  • □ No cracks or chips on housing
  • □ Pins straight and undamaged
  • □ Threads clean and undamaged
  • □ Locking mechanism functional

Cleanliness Check (1 minute)

  • □ No salt crystals or debris
  • □ Mating surfaces clean
  • □ O-ring groove clean

Functional Check (2 minutes)

  • □ Connector mates smoothly
  • □ Locking mechanism engages
  • □ Electrical continuity test passes

Red Flags – Do NOT Dive If:

  • ❌ O-ring damaged or missing
  • ❌ Pins bent or corroded
  • ❌ Housing cracked
  • ❌ Continuity test fails
