Location: SE, WI. | Depth raiders have several chambers. You will have to find the right chamber that has the rattles. Either hold up to light, or if you have access, x-ray the thing. Drill a small hole, start dropping super glue in. Let sit overnight. If still rattles, drop more in till solidified. Or, you could spray in spray foam. Then seal up hole. Not sure why you would want to subtract sonics. I do the exact opposite! JD |
