Buy SeaBis Portable Master System. Consequently, 100% prevent marine corrosion CAUSE, permanently.  NOTE:

* SeaBis may be made portable by fitting battery clips:

One SeaBis Master with battery clips can be moved battery bank to battery bank or boat to boat. All wires, including Current Sense, – green/yellow, may be extended hundreds of meters.  NoteSeaBis indicates current on the circuit it is connected to.  Therefore, not on battery banks while moved elsewhere – connected elsewhere. Intermittent or new causes MAY occur while connected elsewhere, so require permanent installation.

Also: the number of battery banks being monitored by SeaBis Master may be increased by using Battery Switches “Both” or “Emergency”. So paralleling battery banks.  *** ONE SeaBis Master will monitor them all. ***

In addition, in 3 easy steps.  Above all, we will guide you through preventing the ONLY cause.  That cause is stray current.  Similarly, stray current is 97% of ALL corrosion.  The remaining 3% is galvanic (very close proximity of different metals).  Galvanic is easily prevented after Marine Electrolysis is prevented. In conclusion, the reason we supply an 8-year money-back guarantee and warranty is we are 100% correct. Similarly, we supply 8 years free support because causes, moisture, carbon dust, new equipment, impact damage, will reoccur.
