Marine Corrosion CAUSE Stopped. 100%. Permanently. In 3 easy steps.

Photograph proof SeaBis Master System stops marine corrosion CAUSE.  Permanently. So rely on SeaBis:

Corrosion CAUSE prevented, permanently
Marine electrolysis corrosion CAUSE prevention

Reading time to a point where we will take responsibility is one minute.

Guarantee, warranty and support:

We know SeaBis Master will prevent the CAUSE of marine corrosion.  Therefore, we guarantee (the equipment) and warranty (the function- SeaBis Master System) for 8 years. Experience has taught us CAUSE/s may reoccur.  So, we provide free support for 8 years. Contact us

Verify that which we state is true:  

At Wikipedia: Important, note that the Wikipedia equipment power supply is red and black.  Therefore, direct current (DC) or battery power.  Additionally, confirmed in the first text as DC.  It is not shore power (AC).  So, why use a device in shore power such as a transformer or “Blocker”?  Verify, click:  Wikipedia – electrolysis.

The reason we provide an 8-year guarantee and warranty is we are 100% correct.

HINT:  weed growth common CAUSE is a rough surface. Often, the CAUSE of rough surface is electrolysis and easily stopped.

Procedure to stop marine corrosion:  To prevent all cause/s is easy:


Connect brown wire to battery positive.  Blue wire to battery negative.  Green/yellow (current sense) wire to metal hull or metal engine body.

Stopping corrosive current:

Step 1 of 3. 
Identify the types of corrosion SeaBis Master System prevents

Identified in the photos in the above carousel.

Step 2 of 3.
Understand the CAUSE, stray current:

Where there is a battery and leakage to the Earth, stray current flows.  Above all, stray current is the ONLY cause of marine electrolysis corrosion.

External proof:  Wikipedia electrolysis.  Wikipedia specifically states DC – battery power.  NOT AC – shore power. Do not waste your money on AC “fixes” while corrosion attacks.

Therefore, when we prevent the DC that is the ONLY CAUSE of stray current, we prevent the corrosion. That is why we 100% succeed. Link: Guarantee and warranty.

Step 3 of 3. 
Prevent the CAUSE, stray current, permanently:

Switch off equipment until SeaBis Master LED is Normal (green). Turn on all that cause Normal. – not Caution, Serious or Critical

Consequently, the equipment that is a CAUSE now has no power. So, is easy to identify.  

In conclusion, to repair the CAUSE, follow How to Prevent Corrosion.  Or contact us:

Just selling SeaBis Master System is not good enough for us.  We want you to succeed.  New causes will occur. Therefore, we provide 8 years free support.

Multi-meters, will not help and will risk your life:

SeaBis Master responds to 10 millionths of an amp of current.  Corrosion starts to 20 millionths of an amp of current.  SeaBis Master measures current as current. Multi-meters, apart from being in the wrong circuit and risking your life, have a response of 200 millionths of an amp.  In current modes, multi meters measure voltage, not current.  Multi-meters worsen the situation.  SeaBis Master System responds to current as current. SeaBis Master System prevents the CAUSE of corrosion: current.

External proof:  Wikipedia electrolysis.  Wikipedia specifically states DC – battery power.  NOT AC – shore power. Therefore, do not waste your money on AC “fixes” while corrosion attacks.

Marine corrosion CAUSE prevention:

* SeaBis becomes portable by fitting battery clips:

One SeaBis Master with battery clips when moved battery bank to battery bank or boat to boat and will monitor that connected to.  All wires will extend hundreds of meters.   Stray current flowing in the circuit SeaBis is connected is displayed.  Therefore, not on battery banks while moved elsewhere – connected elsewhere.  Intermittent or new causes MAY occur while connected elsewhere, so require permanent connection.

*  How to increase the number of battery banks connected to SeaBis:

By using (link): Portable SeaBis Master or Battery Switches “Both” or “Emergency”.  Therefore, paralleling battery banks. ONE SeaBis Master will monitor all parallel battery banks.  Contact us with SeaBis Master results for a wiring diagram and support.

How to Prevent Marine Corrosion, understand the CAUSE:

Voltage versus current – critical importance. 

Voltage is the POTENTIAL for current to flow. Multimeters measure voltage in voltage and also in current modes. Multimeters measure the cumulative voltage of everything within at least a kilo meter.
Current is the ACTUAL energy flowing.  SeaBis Master measurers CURRENT through your boat ONLY.  To an accuracy 10 parts in one millionth of one amp.

Multi meters on current ranges actually measure voltage.  Therefore, using a multimeter, probe etcetera MUST fail.  That failure WILL cost you increased corrosion in an *exponential manner. 


Using SeaBis Master so measuring CURRENT with absolute accuracy then disconnecting until that current ceases WILL prevent the CAUSE100%, permanently.

* Exponential tipping point where corrosion is self-increasing:

Corrosion roughens the surface.  As the surface is roughened so stray current increases, so corrosion increases …. Prevent the CAUSE with SeaBis Master System as soon as possible.

SeaBis Master System prevents the CAUSE of electrolysis corrosion.

ALL Battery positive LED’s – contact us immediately. Especially if you have both 12 and 24 volts. Fire risk is stopped.

SeaBis Master LED’s explanation:

Your work is reduced by 50%: SeaBis Master displays battery side causing the fault/s.  “Battery positive red” or “Battery negative black”.

1:  Normal, either (green) = the stray current is far too low to cause corrosion.
2:  Caution (amber) = very low current.  There is risk a fault can become serious

3:  Serious (red) = visible corrosion in 6 months

4: Critical (flashing red) = visible corrosion in 3 months

5:  AC Only (flashing red) = your batteries, electronics, and you are at risk.  Excessive AC (110/240) on top of DC (battery). Common cause is power supply Active, Neutral or Earth reversed so your life is at risk. AC is in excess of 2.0 volts.  Correct AC is 0.02 volt.  So, at least 100 times the correct AC.

All battery positive LED’s then contact us immediately.  There is a fire risk that is stopped.
Real life movie follows.  Made, to say thank you, by the yacht Owner:
An extremely complex commercial yacht.  In conclusion, ALL causes of marine corrosion are prevented. Permanently.
In addition, most vessels need only one SeaBis Master.

Busy? There is no need to read any further.  

We will, step by step, guide you or another through permanent prevention of all stray current.  That is the ONLY  CAUSE of 97 % of all corrosion, prevented.
