I’ve been meaning to add a gas detector to Blue Opal’s bilge area for a few years now, and finally got it done. I opted for a Pilot Mini via SVB, and wiring it in was trivially easy (though I need to re-site it due to the power cabling I had not being long enough).
The unit itself.. well, it’s pretty cheap plastic, and I think if I had a 3D printer I could probably create a much better case for it. It’s a pain to take apart to get the wires on to the terminals, and it’s an even bigger pain to put back together. However, I only have to do that every two years, so the next time will be in 2026.
