I came across a situation in my campaign where our druid used a Sleet Storm to obstruct the view of some bandit archers. As a summoner, I decided to send my eidolon in and start summoning Earth Elementals to enter the storm and bash the bandits to death, as Earth Elementals and my eidolon have tremorsense.
Our GM accepted this as reasonable, based on the tremorsense description.
However, our druid wanted to then summon dire bats, which have blindsense. According to the pathfinder definition, blindsense would work in a sleet storm, but we all know that bats use echolocation, and not "blindsense".
It doesn't make sense for Paizo to create a million types of "visions" and "senses" in their books (as every creature is slightly different), so should dire bats be able to see in a sleetstorm (knowing bats truly have echolocation, and not blindsense)?
