• A personal transmitter or radio beacon which is worn conveniently on the body. This transmitter may be manually activated or automatically activated when a person falls in the water.
• A receiver which is connected to an antenna and may be mounted on a boat or in a land base station (such as Coast Guard).
• An ‘omni-directional’ antenna which is connected to the receiver and receives a distress signal from any Seasafe transmitter within 360 degrees and activates a visual and audible alarm on the receiver. This antenna is permanently mounted on the vessel or on an antenna tower at a base station.
• A fold-up directional antenna. This is connected to the receiver after an alarm signal has been received. This antenna provides an indication of the direction from which a distress signal has been received. By following this direction, the victim’s location will be identified

• The transmitter may be manually or automatically activated
• Once activated the transmitter may continue to transmit for up to seven days
• Use of a very hi-bright light emitting diode provides good visual contact over distance at night or in poor weather
• A number of mounting options are offered. The device may be worn on the upper arm using an ergonomic arm band or attached to a pocket or webbing using a custom belt-clip
• A unique coded signal is transmitted whereby no interference is caused to other equipment and no interference is received by other equipment
• The Seasafe transmitter is a personal device worn by each person on board a vessel
• Use of the optional “dive-cap” allows Seasafe to be used by divers. Removal of the dive-cap by a diver in distress will result in immediate activation of the transmitter. Divers surfacing out of sight of the dive boat or getting left behind, can easily be tracked and retrieved by the skipper of the dive boat using the Seasafe receiver. No more “Open Water’ experiences!

• The receiver is able to operate via the 12 volt DC supply on a boat, via five rechargeable NiMH batteries which are continually charged whilst connected to the boat power. The receiver is also able to operate in a base station via a 240 V AC to 12 VDC adapter.
• Full use has been made of discreet switching controls via a fully waterproof membrane keypad. There is no ‘mechanical’ switching or instrument adjustments.
• Adjustable ‘audible’ signal strength indication which has volume level control. Receiver is supplied with a set of head phones for audible signal strength indication under high ‘ambient’ noise conditions. Audible tone frequency and pitch increases when antenna is pointed towards victim.
• Visual signal strength indication via 10 colour coded LED’s.
• Standard auxilliary output which may be interfaced to via an external relay to engine cut-out, GPS , klaxon alarm or flashing on-board light.
• Optional rubber protection holster and neck strap for portable use.
• Receiver may be used as a portable device when disconnected from the vessel with battery life up to 12 hours.
• Dashboard mount receiver bracket.
• Signal transmission and receiving ranges:
  • Up to 30 km from boat to victim
  • Up to 45 km from victim to base station (antenna at 15 metres)
  • Up to 100 km from aircraft or helicopter to victim (flying at 1500m)
• The receiver is only capable of receiving the specifically coded signal from a Seasafe transmitter. This means it is not susceptible to any interference from other sources.

• The Seasafe antennae system comprises two individual antennae
• An ‘omni-directional’ antenna and a ‘directional’ antenna
• The omni-directional antenna is a marine grade fibreglass antenna which is permanently attached to the vessel. Preferably mounted as high as possible as increased height results in increased distance from which a distress signal may be received. This antenna is connected to the receiver at all times and will receive an instant distress signal from a Seasafe transmitter within 360 degrees.
• Once an alarm is received and the receiver is switched over to ‘search’ mode, this antenna is disconnected and the ‘directional’ antenna is connected.
• The directional antenna is collapsible and may be folded up for easy stowage on a vessel when not in use.
• When connected to the receiver in ‘search’ mode, this antenna will indicate in which direction the strongest signal is being received. The vessel will head in this direction in order to locate the victim.
• Optional directional-antenna mast-mount adapter
