I prefer results to be as close to accurate as possible. I use a dedicated device, not a phone, when I put out game cameras or traps. The more accurate the results, the quicker they are to check.

I guess I'd reverse the question. Why wouldn't you want the greatest level of accuracy you can get? Maybe you want to track your property lines? Maybe you want to accurately mark where your access point is for your septic tank? Maybe you just want to hide Easter eggs or buried treasure?

I'm not sure why anyone would want a tool that is less accurate than it can be, assuming it is also reasonably affordable.

Lane detection, self driving cars, drone delivery and of course meeting your Tinder date in the middle of a rock concert.

Where signal strength is low (in the mountains or a building).

When moving slowly (walking).

When precise coordinates are needed (self driving vehicles).

When precise altitude is needed (airplanes and drones).

When tracking smallish things on a person (head tracking for augmented reality).

When performing certain scientific measurements (continental drift).

Finally, so that when I'm sitting at a stop light my navigation doesn't freak out and suddenly think I'm moving in the opposite direction.

I'm sure there are tons more.

For locating things accurately? Imagine I found a fossil in a rock field and wanted to share its location with you - you'd want more than ±5m accuracy to find it.

Accurate geotagging of photographs for starters. From my experience the results can be wildly off and at times my phone doesn't even get a GPS signal.

Better Pokemon Go.
