This is a two-step multicache that involves underwater searching. The underwater visibility might be poor so search with patience.
The first part of the cache is in the given coordinates. The cache is on a few meters depth, so it is achievable even without a scuba gear. There is a piece of plastic that has a hint to find the final step. Note, that you do not need to move the plastic to read the hint. If you cannot find this hint the encrypted hint might be helpful.
The second step is a micro-size cache box, where you can log your visit. Reaching this cache doesn't require diving but there is still a risk of falling into water. Both steps are rated T5.
- A diving mask or swim goggles
- A rope
- A waterproof flashlight
