This is a Loos sensor, what else do you need to know. I had just moved a stay and wanted to write down all the charges. Glad I did, a couple of the lower shrouds weren't tight enough and I had the riggers adjust them. (Yes. I could have customized them, but they got it wrong!) Even if you don't plan on customizing your own rig, it costs money to keep things in check. One note: I didn't buy the 'right one', I should have bought those in the next step below as some shrouds are a bit small. However I can still use it as they are within the scale and my next boat will be larger so I think I made the right choice.
