+# Products #
+
+These products are available for purchase:
+
+* [TeleMetrum](TeleMetrum/)
+was our original (and still our most popular!) product, a dual-deploy rocketry
+altimeter with GPS and RF telemetry link.
+
+* [TeleMega](TeleMega/)
+is a high-end flight computer with 6 pyro channels, tilt limits, more and
+better sensors, GPS, and RF telemetry link.
