Directional & Non-directional Markers

Most of the times, wrongly promoted as “CAVE” markers (only), those little pieces of diving tool are very important for WRECK diving as well, because in fact, are designed for OVERHEAD ENVIRONMENT DIVING!

So, whatever penetration is made, CAVES or WRECKS, the markers are there to be used accordingly, as per your training  protocols. Don’t used them without a proper training, this could lead in miscommunication or even fatal accidents of you, your buddy team or other participants in diving activities in that area!

A (vary) basic information about markers can be found here on  TDI blog.
