Sea-Tag - Man Overboard Wristband. Ref17: MZ-47101
The Sea-Tags wristbands continuously send a signal to one or more on-board smartphones supporting the Sea-Tag app. When the wristband is immersed in water or out of range, communication is lost and the phones monitoring it trigger an audible alarm and record their GPS position.
Sea-Tags use a proprietary version of Bluetooth with superior range and low batter consumption. The wristband uses a standard coin battery and will last 600 hours in continuous operation. Bluetooth does not require a phone signal but for single handed sailors within phone range the Sea-Tag app can be configured to send a test message when activated.
After an alarm is triggered, the Sea-Tags app displays the boat position with the direction and distance to the location where the app was first activated.
Sea-Tag provides an immediate man overboard alarm; it facilitates a swift turnaround to reduce man-overboard drift and aid recovery.
