    Equipment Note: Replacing Our ROV Tether

    March 11, 2026 admin

    Our ROV’s main tether reached end-of-life this quarter after five years and roughly 900 dive-hours, showing enough insulation wear on inspection that we grounded it rather than risk a mid-dive failure at depth.

    Replacement tether and connector work is one of our largest single maintenance costs, and not a glamorous one to fundraise around — but it’s the difference between a safe dive program and a lucky one.
