Today, Pro Mariner is the industry leader in marine and mobile battery charging, trusted by recreational boaters, tournament anglers, and professional marine operators worldwide. Now part of Navico Group, the brand continues to innovate advanced power management solutions that keep vessels energized and ready for adventure.</p><h3>Comprehensive Marine Electrical Solutions</h3><p>At the heart of Pro Mariner's product lineup are their <a href="/7504-pro-mariner-battery-chargers-200141">battery chargers</a>, which range from compact waterproof models to sophisticated multi-bank systems with digital controls. Pro Mariner chargers can sense increased demand from auxiliary batteries and divert up to 100% of available power to that battery, while being fully temperature controlled and microprocessor controlled to prevent overcharging. These chargers are specialized for all marine battery chemistries including flooded, AGM, gel, and lithium (LiFePO4), using digital multi-stage charging technology that ensures efficiency and longer battery life.</p><p>Beyond charging, Pro Mariner offers critical electrical components including <a href="/7504-pro-mariner-inverters-200588">inverters</a> that deliver pure sine wave AC power for sensitive electronics and high-demand appliances. The ProMariner True Power Inverter Chargers can switch near instantaneously to backup power when AC power is interrupted, making them ideal for backup systems running sensitive equipment like computers and printers. The brand's <a href="/7504-pro-mariner-battery-isolators-voltage-sensitive-relays-200144">battery isolators and voltage sensitive relays</a> ensure proper power distribution across multiple battery banks, while their <a href="/7504-pro-mariner-galvanic-isolators-200465">galvanic isolators</a> protect against corrosion caused by stray electrical currents in marina environments.</p><h3>Built for the Marine Environment</h3><p>Pro Mariner products feature IP-rated waterproof construction, corrosion-resistant components, and robust design engineered specifically for harsh marine environments. The ProSport and ProNautic series exemplify this commitment, offering distributed on-demand charging technology that intelligently allocates power where it's needed most. Pro Mariner won the 2010 IBEX Innovation Award, recognition that underscores their position at the forefront of marine electrical innovation.</p><h3>Why Marine Professionals Choose Pro Mariner</h3><p>Whether you're maintaining a fishing boat's trolling motor batteries, powering a yacht's house bank, or managing electrical systems on a commercial vessel, Pro Mariner delivers reliable performance.

The Pro Mariner 12072 is a high-performance battery isolator designed to manage dual battery systems with dual alternator capability. This 70-amp isolator ensures that each battery bank charges independently while preventing discharge between batteries when the engine is off, making it ideal for marine vessels, RVs, and emergency vehicles that require separate starting and house battery systems.
Key Features:
This battery isolator is engineered for applications requiring independent charging of multiple battery banks without the risk of cross-discharge. The gold-plated terminals provide superior conductivity and long-term durability, while the efficient design ensures maximum charging performance from your alternator system. Suitable for boats, motorhomes, work trucks, and any vehicle requiring battery isolation and management.
