ENOS is the guide for a quick rescue with Technical Readiness Level 9
Pro
Ranges up to 28 nautical miles!
In order to receive the alarm over very long distances, the successful ENOS system was further developed in ENOSpro.
It consists of the ENOSpro transmitter ETXpro and various models of the ENOSpro receiver – which meet all requirements of the respective mission and the boats or ships used. Of course, the ENOSpro mobile system can also be used in inflatables.
If desired, the ENOSpro transmitter ETXpro can also be combined with any “normal” ENOS receiver.
Depending on the radio receiving antenna and the height at which it is installed, the signals are transmitted up to 17 nautical miles. With the special antenna EF5pro-S even a range of up to 28 nautical miles is possible.
ENOS receiver ERXpro: Individual, for all uses and requirements
The ENOS receiver ERXpro is available in different variations, ready for every use.
- Mobile – for use in rubber dinghies or permanently installed in the ship’s steering position
- Additional external radio receiving antenna increases the transmission range
- Reception, evaluation and display of several signals at the same time
- Available with encrypted radio frequency on request
Light in weight, easy to use
The ENOSpro transmitter ETXpro has very compact dimensions: 200 x 35 mm (L x D) and weighs only 160 grams with batteries.
It is very easy and versatile to attach to the equipment.
It is only switched on in an emergency.
Its switch is easy to operate, even with cold fingers and thick gloves: just turn it 180 ° – that’s it.
So it can be switched on unmistakably even in the dark!
The ENOS transmitter ETXpro is the result of consistent engineering
The antennas are protected inside the housing = maximum protection against antenna breakage
An update is sent every 15 seconds = the crew is always informed about the current position of the comrade
Permanent transmission of the actual position in real time
Pressure-tight tested up to 150 meters, extendable if required
ENOSpro is available in individual (company) colors and camouflage
Principle
The Ship
The ENOS receiver on the ship uses the GPS satellites to determine its position [A].
The Divers
After surfacing, the divers switch on their ENOS transmitter, which sends its signals directly to the ENOS receiver.
Without detours! That is why ENOS is self-sufficient.
GPS-Position
Immediately after the ENOS transmitter has issued the 1st alarm, it determines its GPS position [B] via the GPS satellite.
As soon as he has this data, he also sends it directly to the ENOS receiver.
ENOS-Screen
From its own position [A] and the GPS position [B] of the ENOS transmitters, the receiver calculates the exact distance and direction to the aborted divers.
He displays this life-saving data in an easy-to-understand graphic on his screen.
Speedy Rescue
ENOS-Screen:
Warning window with sender identification and ID
The alarm and the GPS position are transmitted by the ENOS transmitter on a license-free radio frequency.
The ENOS emergency call is toll-free and free of charge and does not interfere with the GMDSS (Global Maritime Distress and Safety System).
After only 5 seconds, the ENOS receiver receives the 1st alarm:
A high frequency alarm sounds and a warning window appears on the screen with the message “NEW ALARM!”
If the divers are still in sight, they can now initiate the rescue, otherwise the crew only has to wait a few minutes for the ENOS receiver to display the divers’ exact GPS positions.
Beacon
Handy and compact
The ENOS transmitter is only 20 cm long, has a diameter of only 3.5 cm and weighs only 165 grams with batteries!
It has no influence on buoyancy.
With the help of its bag, it can be conveniently attached to diving equipment in various ways.
Permanent updates, LEDs that can be seen from afar
The ENOS transmitter sends its signal every 20 seconds and the crew always knows the current position of the diver.
These short transmission intervals ensure reliable emergency call transmission even in heavy swell:
If the diver is in a trough of waves while the ENOS transmitter is transmitting, it is very unlikely that his signal will be received because the water wave absorbs (“swallows”) radio waves.
30 or 60 seconds later, however, the diver is on the crest of the wave and the ENOS signal can be received again.
30 or 60 seconds later, however, the diver is on the crest of the wave and the ENOS signal can be received again.
There is an LED on his head that flashes regularly when in use and is visible from afar. This also increases security.
It also shows the battery status and the function mode during operation.
Robust housing, robust workmanship
As light as the ENOS transmitter is, its housing is robust: no water ingress!
The antennas are also located there, which prevents antenna breakage – this is unique in the world!

Easy to use
To switch on the ENOS transmitter, its red foot is rotated 180 ° – that’s it.
No confusing buttons that are difficult to operate with neoprene gloves (if at all) … That is why the ENOS transmitter is easy to use even with cold, clammy fingers and even with thick dry / diving gloves.
After switching on, the asymmetrical switch position clearly shows “ON” (picture on the right) – important and reassuring in this stressful situation!
Then it just has to be held up (photos above).
This is important so that the emergency call is transmitted without interference, because the water wave “swallows” / absorbs the radio wave.
Transmission range up to 28 nautical miles
Depending on how high the radio receiving antenna is mounted on board, the ENOS emergency call can reach up to 28 nautical miles.
Why batteries instead of rechargeable batteries?
The ENOS transmitter is powered by lithium AAA batteries, which are available all over the world. You can change the battery yourself, it is not necessary to return it to us!
The use of batteries has unbeatable advantages over rechargeable batteries:
- Batteries lose performance over time, even if they are not used
- Batteries have to be charged regularly and permanently
- An unnoticed power failure at night has negative effects on the capacity of the battery
Our world record: Outstanding power management
The running time of the ENOS transmitters is 170 hours = one week!
This is the world record among emergency transmitters, set by our development engineers.
This means that he always has enough energy, even after several rescue operations, because ENOS missions usually only take a few minutes.
When the batteries should be changed can be easily recognized by the flashing signals of the LED and is described in the operating instructions.

For your safety
The idea that a diver is floating in the open sea with a transmitter whose battery does not have 100% performance – although it has been charged all night – is a horror …!
That is why we will never install rechargeable batteries in our rescue transmitters – for your safety!
The ENOS transmitters are supplied with lithium batteries that have a capacity guarantee of 18 years!
This means that the batteries will reliably deliver full performance even after many years.
There is no need to fear a loss of performance and the charging capacity does not have to be constantly monitored.

Immediate alarm
Immediately after switching on, the ENOS transmitter sends a 1st alarm to the ENOS receiver.
A short time later it has determined its exact GPS position, which it also sends directly to the receiver ⇒ ENOS PRINCIPLE
Now the crew knows where the diver is drifting – just a few minutes after he surfaced ⇒ ENOS SCREEN
Receiver
The perfect combination of fixed installation and high mobility
ERX-P
Always in the captain’s eye:
The ENOS receiver with touchscreen installed permanently in the helm.
ERX-S
The permanently installed receiving station receives the emergency call from the drifting divers and evaluates it.
This data is sent via Bluetooth to a tablet that serves as a portable screen.
Screen
The ENOS screen can also be clearly understood under stress and does not require any knowledge of navigation.
The + in the middle of the circle is the ship, the arrow at the top points in the direction of travel.
The numbers 1 and 2 show drifting divers in relation to the boat.
Their sequence is determined by the receipt of the emergency calls.
The radius of the circle automatically adjusts to the distant emergency call.
The table next to the circle gives precise information about:
- Number of emergency calls received (No)
- Identification / identification of the sender (ID)
- Distance and
- Direction to the divers (bearing)
The ship data can be seen at the top right of the ENOS screen:
- Date and Time
- Speed
- Course
- GPS information valid
- Number of GPS satellites (one green bar per satellite)
