MNemo • Cave Survey Data Acquisition
Do you want to do fast and accurate cave survey ?While you swim in the cave and you want to do cave survey data acquisition, simply clip MNemo on the line. Stabilize a couple of second, swim at normal pace until the next tie-off. Stabilize again a couple of seconds, unclip and re-clip after the tie off, repeat ... MNemo records the length of the line you just swam along, the depth/tilt angle at start, at the end, as well as the heading. These data get directly integrated in your favorite 3D cave mapping software: Ariane.

Without exception, Ariane's line and the Mnemo offer the most sophisticated, efficient and practical means to survey and process underwater cave data.
It's an incredibly easy and accessible system with a lot of options and capabilities. One of the many features that is excellent is being able to overlap it with google maps and show in real time where the cave is located. Cuts the survey time and effort in half.

Skanda Coffield –
Ariane’s Line is the best and most user-friendly of all cave mapping programs available. It’s features make it super usable and there are so many other capabilities in there that you can grow into using. The Mnemo makes cave survey far more efficient and safe. The ease of data entry alone makes it worth its weight in gold!!!
Max Ardizzoni –
I can’t imagine myself collecting data during a cave dive without my Mnemo. An invaluable aid to speed up data collection, especially in the presence of strong percolation and halocline
