I think a more apt description would be that the DistoX has killed the SAP.
It is absolutely true.
Note: for DistoX use primary Lithium AAA cells from Energizer. They have the highest capacity from all AAA cells, they work from -40 to +60 Celsius without significant loss of capacity, they will not discharge 15 years (!!!!!). They are not cheap
Imagine next workflow:
1. From station 1.0 (you must follow the Toporobot logic of station numbering, series, etc. -
http://www.geo.unizh.ch/~heller/toporobot/ ) you start measure the splay shots - it means you measure the important points and objects around the station 1.0.
2. You measure the surveying leg from station 1.0 to station 1.1 three times.
3. On your PocketPC in EasyTopo program you check the shots and draw the map, extended elevation and profile (optionaly) based on real measurements - splay shots and leg in map and elevation editor.
4. Go to station 1.1 and repeat.
You should receive in scale drawn map and elevation of surveyed part of cave at the end of your surveying trip.
At base camp, or at home you export data from EasyTopo and import both data and sketches into Therion. You redraw the map, elevation and profiles in Therion to receive the final map. Or you may export from Therion only the sketches to PDF and print them too.
Calibration is question of 15-20 minutes.
