Scuba Diving Trip

(continuation)

On the seventh day of our scuba diving trip to Sulu for refloating a sunken ship, the sky is dark but it's not raining. As you expect its a bit wavy but not too much but enough to confuse the sonar. We have to repeat the scanning 3 times before we got the exact position. Our captain anchored down and we inspect the current underneath. Water is darker than we expected. We thought it's going to be clear since it is a province and only few ships passed by within the area.

We dropped our bathymetry or sounders; our pre-measured rope tied with a heavy u-clamps. First is to measure depth of the sunken ship. Second purpose of our sounder is for our decompression guide as we ascend. We drop it thrice to make sure since the current is strong. On the third time we put heavier metals to stabilize descension. Some commercial divers or professional divers use computerized bathymetry but since we dont have budget for other gadget.
