Apart from single points records, the SEAYOS enables continuous routes recordings at the surface: it's the "tracking" function. During the "tracking", the SEAYOS remains at the surface and is towed by the diver (contrary to punctual points records for which the SEAYOS remains only a few seconds at the surface), like the buoys towed during drift dives.


Background maps:

They enable divers to locate themselves in relation to pre-identified zones. Background maps are specific favourites composed of lines or/and polygons imported from the SEAYOS PC interface. They can also be trackings from previous dives, converted into favourites directly from the SEAYOS.



Annotations allow to associate a symbol with the recorded points to facilitate their post-dive use.

Multi-point guiding mode:

It's a point-to-point guiding function without intermediate position records at the surface.
