I had a box for years but found it to be not great when sitting in a boat in a flat calm with spooky fish all around and you need to retrieve something at the bottom of the box,just watch the fish disappear and daggers from your boat partner
I have tried a couple of bags since then but find them hard to organise and not great on a wet day.The ideal solution in my opinion is a box and put some kind of sound proofing on the base.
