  • @bob · Jul 9, 2026 · 2024 Tioga cruises

    Three v2 deployments off the R/V Tioga. The new seal stack held; the external LED is genuinely useful.

  • @alice · Jul 9, 2026 · 2023 lab benchmark

    Used the v1 on a quick lab benchmark before committing to the v2 redesign. Power draw matched the spec within 8%.

  • @bob · Jul 9, 2026 · 2023 Vineyard Sound mooring

    We deployed two v1 units on a coastal mooring for six weeks. Both pulled clean samples; one had the known seal leak above 200 m.
