Penetration and safety
Wreck penetration demands training and equipment discipline. Enter only with a dive light and guideline awareness. Many sites allow limited penetrations; others suit external exploration entirely. Know your depth limits and gas reserves before descending.
Silt management matters on wreck dives. Avoid unnecessary movement inside holds or cabins. Buddy communication becomes critical in reduced visibility and confined spaces. Advanced training specific to wreck diving is strongly recommended before attempting deep or overhead environments.
