Light Monkey E/O cord 9mm

An E/O cord (Electro-Oceanic cord) is a specialized, wet-matable electrical cable designed for technical diving. It allows divers to connect or disconnect electrical devices—such as primary light heads, battery canisters, and heated drysuit undergarments—underwater without flooding the connection or shorting out the battery. The 9mm heavy-duty cable option features a thicker, reinforced jacket compared to standard thin cords (like 5.75mm), making it far more resistant to abrasion, pinching, and harsh overhead environments like caves and wrecks.

Light Monkey 4' E/O Cord (9mm)

Upgrade or replace your technical diving power setup with the heavy-duty Light Monkey 9mm E/O Cord. Engineered for extreme technical, cave, and wreck environments, this wet-pluggable cable provides reliable electrical connection between your battery canister, primary light head, or drysuit heating system—even when connected or disconnected underwater.

Featuring a heavy-gauge 9mm outer jacket, this cord delivers maximum durability against abrasion, tight squeezes, and sharp edges. Whether you are building a custom lighting rig, powering a heated vest, or swapping out a damaged cable, Light Monkey's gold-plated contacts ensure low resistance and leak-free power delivery dive after dive.
