protection cover, for your box or the coil?? I have one for my BOX, an "rain/dust cover"..., hard to use, as it inhibits finding pinpoint/ground bal button, and knobs with glove on, but does the job on dust and sprinkles, but not sure in any downpour, if it would be protected - I later went to a clear vegetable bag from grocery store, and a big rubber band, then I can provide slack enough to move knobs and find pinpoint easily - even can see battery charge icon, whereas the rain/dust cover hides that icon. For the store-bought packcloth and plastic cover, ask Teknetics as they have one for their wannabe version of the G-Bug-Pro, same size and shape..., probably cheaper. Hope I helped. hey, I'll sell you mine.....
