The GOST Phantom M is designed for boat owners who want to monitor certain conditions on board the vessel. This version of the system will monitor the shore power, high water in the bilge, low battery voltage and smoke detection. When an event occurs the GOST Phantom will call and/or text up to 8 phone numbers alerting recipients to the incident onboard the vessel. Additional monitoring sensors are available which help protect against thousands of dollars in losses like the freezer temperature sensor, which alerts you if problems occur with bait, food or ice storage freezers.
