Remember, there is no recompression chamber in East Timor. The nearest are in Darwin and Bali and are expensive to get to and a long way away. Remember also we have no coast-guard. No one will come to save you. You are basically on your own. Plan your dives with this in mind and you should be OK.
Always dive within your limits. Let someone know where you are diving and an approximate time for your return. Always have a basic first aid kit in your vehicle. I also take a tyre inflator with me. This fixes to the low-pressure inflator hose on your reg. It will get you home in an emergency. Most tyre pressures are around the 30psi mark. 10 bar in your empty tank is equivalent to 150psi.
