It isn't a must have, but a "be sweet if it could fit in a bucket". Haha. The 5 gallon bucket is a universal ice fishing tool, and would be helpful if the flasher accommodated it.
I am looking to be more efficient going from hole to hole. Would love a sonic ice hopper, but it isn't compatible with the 7. The bucket serves as my seat and means of holding my catch. There are times its a struggle to carry my gear from hole to hole in one trip. Be nice to have the option of putting the flasher in the bucket on top of my catch to help handle the load. I don't like to drag my sled from hole to hole, b/c of the noise created. I use a Jet Sled Jr late season to be a minimalist. Some spots are remote access, or I have to walk a LONG WAYS to get to prime spots. Freeing up area in the sled by being able to put my flasher in a bucket, on top of other gear, or on top of my catch at the end of the day would be nice. Most of the time I am fishing out of my portable and the LX7 soft pack is perfectly fine, its just the hole hopping situation I would like to improve upon.
