Anti-Anxiety Machine

Do you worry about your boat when you’re not aboard? Boatsense Solutions’s KISS-principle monitoring system is an easily programmable GSM cellular modem that’s potted in epoxy. Drawing only 130 milliamps, it stands perpetual watch, ready to send text messages wherever GPRS data service is available (which is along much of the world’s coastlines). It automatically monitors battery levels, plus has inputs for a bilge-level alarm and three other sensors of your choice. $499 for the unit; $180 per year for up to 20 messages a month.
