Quick Tip: Be Careful With Shot Bags On A Slider
When using a slider right on the ground the grips will often put a shot bag on either side of it so it doesn’t move around. Newer (and likely all) shot bags are now filled with metal shot as opposed to sand. There is a round magnet built into most of these sliders that, when it comes close to the opposite magnet at the end of the slider, it is repelled.
Well, when you put a metal filled sand bag over that, and move the slider towards the shot bag, it will actually act as a magnet and pull the slider into the bag (I don’t actually understand why but someone much smarter than I can explain this) so that slow move to the side, suddenly ends abruptly and you’re stuck. So ask for an actual sandbag or find out how to hold the slider in place in some other way. You’ll be happy you did.
