New Palm OS device

PDA32 Aceeca, a New Zealand company that specialises in rugged PDAs, offers in Fall 2010 the PDA32. 199$ for this Palm TX equivalent (179$ + IR and Bluetooth options), but with a double capacity battery. Read my trial report.


Conduit 0.31 adds GH Topo support, a Windows software that uses Toporobot's data format. We now seek a programmer to adapt and compile the conduit for the Mac and thus support Toporobot/Mac.


Auriga now offers Bluetooth support of the DistoX, a 3-in-1 survey device (distance, azimuth and slope). A Palm OS DistoX calibration program is also downloadable.

Auriga on TV

On October 13, 2008 at 20:00, Télé-Québec's Le Code Chastenay scientific magazine featured a 5-minute report on Auriga and cave surveying we shot in June in Saint-Casimir Cave.

Pit Sounder

Pit Sounder

On May 10, 2007, we tested Auriga's Pit Sounder at Sima de Cabra (Córdoba, Southern Spain) by throwing 10-15-cm rocks into this 116-m open-air pit. By measuring the fall time (about 5 s), Auriga estimated a depth varying between 114 and 117 m!
