FYI : This is obviously not a mass consumer electronic product, but rather a tool aimed at serious cave explorers. Don't expect a fancy/shinny/stylish smartphone-like device. This is a rugged assembly of Delrin around poted state of the art electronic circuitry, some Teflon where necessary and plastic screws to lower magnetic disturbance. It won't even look brand new when you unbox it as all devices will be tested and calibrated both on surface and in water before shipping. That being said it's serving its purpose pretty well.

What our clients say

Don't just take our word for it. Hear what our customers have to say!

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.

  3. 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!!!
