While diving my favorite watering hole today, I thought how helpful it would be to download my dive and have a "map" of sorts, to diagram WHERE I dove, not just depth (my computer already does a depth graph). I currently have an Oceanic Pro Plus 2.

Is there a dive computer that can diagram direction?

You would have depth and direction but no length to the vectors. You would need to assume a constant velocity (or enter something). Towing a GPS in a surface buoy has been done.

Indeed; you'll need a static reference point to have vectors & relative acceleration calculations

Hi,

I have a compass integrated divecomputer (suunto D9) but that doesn't solve your requirement, because, as stated in the other replies, you don't get distance vectors. It'll only let you mark headings. As far as I know the only thing that could do what you want is GPS, but that doesn't work underwater (so far).

Greetz,
D.

There are under water navigation systems devloped(a simple for recreational diving was Uwatec Neverlost), but I don't know if they are available for recreational diving. Due to the properties of water one can forget systems based on electrical signals and what then remains is ultra sound. The Z vector is handled with a pressure sensor and the rest with two tranmitters, simple triangulation.
