TSD Rally Split vs N.S.A.T.

The TSD Rally Split consists of two clocks with different purposes. Master•Time on the left is the rally time-of-day clock. This clock can be adjusted to synchronize with the Official Rally Time clock. Also, the Master•Time clock can be split/stopped by touching the button on the left side. Retouching the button will cause the split time display to disappear. 
Monte•Carlo on the right is a stopwatch with two buttons: one starts and resumes the stopwatch and the other records each lap. When the stopwatch has been stopped, there are three options for resetting it to zero for another start available when you click the Stopwatch Reset Options button below the stopwatch. One option (To Zero Now) is to reset to zero and await pressing the Start button. A second option (Next Minute) is to have the stopwatch reset when the time-of-day clock reaches the next full minute. A third option (Preset Time) allows you to select any time in either minutes:seconds or minutes:cents using the four sets of green or red buttons to increment to the time desired. In order for any of these three options to take affect, you must touch the Apply button on the Stopwatch Reset Options popup. Touching the "Adjust" button opens a popup that allows you to synchronize the Master•Time to the Official Rally Time by making adjustments in increments of +/– 0.1 seconds to account for total errors of as much as + or – 10 seconds. Touch the Lock button to make clock adjustments. Adjust time ahead or behind as needed and, when finished, touch the Unlock button to prevent unintended adjustments. Touch the double Arrows singly or continuously to make adjustments in +/– 0.1 second increments. When unlocked, a chime will sound at 0 seconds and 30 seconds. This audible cue is helpful when synching with an Official Clock. When the Official Rally Clock’s second hand reaches zero, the start of a new minute, estimate the error by which your clock is behind or ahead of the Official time and add or subtract 0.1 second increments. On the clockface displays, time can be measured in either seconds or decimal minutes. Additionally, there are two levels of time precision. One displays two digits for seconds or two digits for hundredths of a minute. For more precision, the other measures and displays seconds as two digits plus tenths of a second or three digits for thousandths of a minute. There are three watch face styles: black, yellow, and white.

Neal's Sorta Accurate Timer (NSAT) is an application designed to help assist with attaining a time closest to the "perfect" time based on a target average speed over a predetermined rally race course. This is accomplished by utilizing a RaceBox GPS device to automatically start the timing based on a preselected time. The course name, distance and finish longitude / latitude are configured and saved in advance. The timer will automatically stop when the finish latitude and longitude are reached. Results of each rally course are stored in a log file. Typical events where this application is used include: Silver State Classic Challenge, NORC, Big Bend Open Road Rally and similar rallies. The app includes preconfigured courses for Nevada and Texas events, but you should always confirm finish line latitude and longitude since race officials may change these without notice. This app also supports "red flag restarts" for the Nevada events. You can also edit courses or even add your own courses for practice at legal speeds. Please note that this app REQUIRES the use of a RaceBox Mini device and is not designed to work with GPS from any other manufacturers. I am not affiliated with RaceBox, but chose their device because it is my personal preference. Understand that this is a FREE app and may not be perfect. I built this app as a way to give back to the open road race community that I love and to provide a reasonably simple solution for those who would like to try GPS timing. Now, just have fun and be safe.
