When my field was new I would leave it up over night and had little problems, but after time and normal wear and tear on the field, the bungee cords will break down, so one night a sudden wind storm came through and blow them away and the next morning my team and I had to go on a bunker finding mission, 8 of them blow over a half mile away over a barb wire fence across a corn field over a pond and got caught in some woods and every one got holes in them. It wasn't a fun way to start practice. Now we drop bunkers every night. We have 4 leaf bowers now and it takes us less then 20 minutes to blow up an entire xball field, it's worth it for us to take them down every night
We run 2 bulk tanks with a 10 CFM compressor and never run out of air with over 30 people filling.
Hope that may help
