and remember it will also depend on the water depth you are in; the FF can ping faster in shallower water. it takes 10x as long for the sound to travel down and back in 200' as it does in 20'

So scroll speed is critical... I wasn't aware of that.. I think I keep the scroll set slower.. Typically I am jigging at around 70 feet, but am often in 90-100 as well.. depends on time of year and time of day...
