+Design Goals;
+<br><br>
+- Complete safety when used in the correct manner. i.e. NO surprise ignitions.<br>
+- Single battery design.<br>
+- Uses only single pole switches for reliability and safety. <br>
+- Parts availability from chain store local outlets that also have internet ordering.<br>
+- Low cost and minimal parts count without sacrificing either reliability or ruggedness.<br>
+- LOW CURRENT igniter (continuity) testing; less than 10ma with a 12 volt battery.<br>
+- Continuity sounders at both the pad and launch units.<br>
+- Full diagnostics of both units AND the cabling without the need for additional test equipment.<br>
+- High current paths are direct with only the relay contacts and a high-current safety switch between the battery and the igniter.<br>
+- Sounders at both ends warn about incorrect operation, including launch key insertion, in a direct and easy to understand manner.<br>
+- Operational range of 750-1000 feet is possible using 16 gauge 3 conductor power cable. Longer range with simple range extenders.<br>
+- Either of the two units may be used standalone for low power launches. (Requires cable adapters.)<br>
