Introduction:
The intention of the software is to provide the marine search and rescue community with some handy calculators that can be used on SAR missions. The App is optimized for portrait orientation on a phone and has not been tested on a tablet.

Feature Summary Overview:

- Direct Twitter Feed from @RCM_SAR posts

- Speed, Distance, Time Calculator. Enter any two parameters and it calculates the third.

- Find Lat / Long functionality allows you to quickly enter a lat / long and the App will calculate your distance along with bearing and also show your current location. You can also automatically map the lat / long entered on google maps.

- Sector Search Timer and Calculator. Can run two full circuits of 9 legs with a 30 degree course change to start the second circuit. User enters search speed and search radius, and everything else is calculated automatically. Timer defaults to 0 degrees for the first leg but any value can be entered. Once timer is started it signals when to turn with the appropriate heading. Timer must be reset when you pass back through datum. Total search time and area are also shown for one circuit. Start time is logged so that it can be transferred to a log book later.

- Expanding Square Search Timer and Calculator. Runs a full expanding square search with 18 legs. User enters search speed and search radius Timer defaults to 0 degrees for the first leg, but any value can be entered. Once timer is started it signals when to turn with the appropriate heading. Search can be paused and then restarted at the beginning of the last leg you were on. Total search time and area are also shown for the search. Start time is logged so it can be transferred to a log book later.

- Night Mode. Sector and Expanding Square Search Calculators have a night mode to preserve night vision.

- Search Log automatically keeps record of all the parameters of your searches and allows you to email the log file to anyone you choose.

- Vibrate. Timers vibrate in the hand when it is time to turn.

- Help. Help is available for Sector and Expanding Square Search Calculators.

KNOWN ISSUE: Entering data in fields (which causes the keyboard to appear) will leave a black bar obscuring the bottom navigation bar on Android 8.0. Working to find a fix. To clear the black bar you need to re-start the App. Navigation is still possible with the black bar showing.
