    As a guy who once came perilously close to pumping a lot of diesel into the wonderful upper North Carolina section of the ICW, I think that this switch looks terrific. I also like how they’ve used Bluetooth for configuration and direct monitoring, and hope we see a lot more of that in used-to-quite-dumb system components like this.

    If you do get diesel in the bilge, maybe you’ll be able to use this one day

      Thanks, David. I guess it’s matter of manufacturing cost versus potential market, but I sure wouldn’t mind floating a plank of oil and diesel absorbing balsa in my bilge.

    Cool idea. But I saw that from Spearman Marine in Campbell River BC Canada back in 1986. This is not new.

    • Ben Ellison Ben Ellison says:

      Thanks, Julian. Spearman still exists, and references a “Liquid Selective Bilge Pump Control system” they worked on in the 80’s:

      But judging from what they sell now, plus the huge evolution of general tech like microprocessors, I doubt that the BG-One has much resemblance except in purpose.

      Incidentally, I recently bought and installed a BG-One, and am quite pleased so far.

        Sure, the Panbo unit has way more functionality, but to claim to be the worlds first oil detecting switch is categorically false.

        • Ben Stein Ben Stein says:

          I don’t see anywhere the claim is made that it’s the first oil detecting switch. Blue Guard Innovations does refer to it as the world’s first SMART bilge pump switch with integrated oil/fuel detector. I don’t think they’re claiming to be the first oil detecting float switch rather their claim is about smart bilge pump switches. Smart is a somewhat overused term and while I personally wouldn’t choose to make claims like that I don’t think it’s at all categorically false.

          The “Panbo unit”? Panbo has nothing to do with developing or manufacturing the BG-One. But Panbo is the first, best, and maybe last marine electronics blog!
