vhbw 10FT ECM30 Extension Cable for Humminbird Transducer

vhbw’s 10-foot ECM30 extension cable replaces Humminbird 720096-2 to extend or reroute your transducer without signal loss.

This heavy-duty extension is designed for anglers and boaters who need extra reach for Humminbird HELIX series units and many PiranhaMAX models. It mirrors the original ECM30 (part 720096-2) performance so your sonar readings remain steady while giving you flexibility in mounting and cable routing. The cable resists corrosion and weather exposure, and plugs in with no tools required, making it a straightforward upgrade or replacement on most vessels.

Will this extension work with my Humminbird HELIX or PiranhaMAX unit?

Yes — the vhbw 10FT ECM30 extension is built to be fully compatible with Humminbird HELIX models (5 through 15) and PiranhaMAX units produced after 2001. It uses the same connector type and pinout as the original factory cable so the fishfinder recognizes the transducer correctly.

• Compatible: HELIX 5, 7, 8, 9, 10, 12, 15 series
• Compatible: PiranhaMAX models manufactured after 2001
• Not compatible: APEX, SOLIX, ONIX, ION series
• OEM-style connector prevents handshake issues and signal drop

How does the 10-foot length help my boat setup?

Ten feet of extra cable gives you more freedom to relocate the transducer, hide wiring, or move the display without stretching or splicing factory cords. This length is useful for larger boats, console reconfigurations, or when routing around obstacles under the deck.

• Allows transducer repositioning for better sonar coverage
• Eliminates need for extension splices that weaken signals
• Provides slack for future upgrades or relocations
• Helps tidy cable runs and secure connections away from interference

What build features protect the cable in marine environments?

vhbw engineered the cable for long service life on the water: a robust outer jacket shields internal conductors, and corrosion-resistant connectors keep contacts clean in salt or freshwater. The thick insulation and precise connector fit help maintain a reliable signal even when exposed to vibration and moisture.

• Thick outer jacket resists abrasion and UV exposure
• Corrosion-resistant metal connectors prevent contact loss
• Secure plug-fit minimizes moisture ingress and vibration issues
• Designed to match OEM electrical performance for accurate sonar

Is installation difficult — will I need tools or programming?

Installation is plug-and-play; no soldering, crimping, or programming is required. Simply unplug the existing transducer cable from the display or junction and insert the vhbw extension between the transducer and the chartplotter, then route and secure the cable as needed.

• No special tools required — plug in and power on
• Maintains the factory wiring scheme and signal integrity
• Ideal for DIY anglers and quick field replacements
• Reduce downtime with a direct OEM-style swap

Who is this for: This 10-foot vhbw ECM30 extension cable is aimed at fishermen, boating enthusiasts, and marine technicians who use Humminbird HELIX series displays or compatible PiranhaMAX units and need additional cable length without compromising sonar performance. It’s especially useful for those relocating transducers, running neat cable routes, or replacing a worn factory extension with a weather-resistant, OEM-quality alternative.
