iPhone Theodolite Question

?ÿ?ÿ?ÿ?ÿ?ÿ?ÿ?ÿ?ÿ?ÿ Iƒ??m not an RPLS; I work the gun on a two-man crew. Iƒ??ve had prior experience with staking jobs where a shot was blocked by a tree and no other options on the staking sheet. When the i41CX+ (HP41 emulator) iPhone app came out I developed a suite of programs that compute angle/distance data for alternatives to test out that I can email to the boss for validation while weƒ??re still at the job. I even wrote a simple program to display the difference (stake sheet ƒ?? shot distance) along with ƒ??to meƒ? or ƒ??go awayƒ? prompts so I tell the rod man the correct direction to move. He gets annoyed with me when I tell him the wrong direction.

So Iƒ??m always looking for ways to improve. While browsing ƒ??Surveying & Geomatics Topicsƒ? I came across one comment about the iPhone app Theodolite that intrigued me enough to take a look and then download it.?ÿ Iƒ??m trying to understand how it can be used for survey work given the low resolution of iPhone sensors relative to even the elderly 5ƒ? total stations I work with. Recent deep snow has kept me from trying it outside so far. Iƒ??d appreciate descriptions of what uses have been found. Questions: Dr. Hunter recommends having the phone solidly mounted when doing the calibration procedure. What phone mounting has been found that works in the field? Is that mount also needed for other purposes or does handheld give acceptable results? Can Theodolite assist with recon work? Even a tape would give more precise and accurate distances?
