Someone posted that covering the holes results in the release of a toxin....don't remember what exactly but scared me a bit. I used to cover my DSE901b hole for a fraction of a second to get better hits (as was recommended in the other post), but since reading that about the toxin being released I stopped. The guys sounded like he knew what he was talking about.
Anyone know what I'm talking about?
I have never heard of that, I sure hope not as I do that every so often.
