I am upgrading my bino harness. I know that debate is never ending on here. I like the forward opening harness system and I am leaning toward the sitka bino bivy for various reasons. That said I want to add on a rangefinder pouch and I am thinking I will add a marsupial. My concern is I know the marsupial harness magnets are powerful enough to throw off a compass or GPS. Has anyone had issues with the rangefinder pouch doing the same or are they small enough and far enough away on the harness to avoid this?
