I don't bother with the helmet on lakes and ponds. Wouldn't wear it in a swamp either. Falling on flat water where the pole reaches the bottom isn't a real concern to me. You can always catch your balance with a pole plant. You might be surprised that you can do a weak rendition of a brace in deep water with a pole too. If you are just learning to pole and not used to standing in the canoe, I can see where the brain bucket might be a good idea though. But when I pole around the perimeter of the local lake, I just wear a nice shade hat.
