400m is the maximum distance.
What is the minimum distance?
How accurate?

Range 15 to 400m at 0.02%. I do not know of a way.
GPS will never make 15m+/- 0.02%. The 400m is no problem.

LIDAR probably but quite a difficult DIY project

0.02% is looking for incredible accuracy

I would imagine a commercial system would be struggling for that accuracy?, and certainly not a prayer for under $100

Here's a sample from a manufacturers website:

https://www.lasertech.com/TruPulse-200X-Laser-Rangefinder.aspx

This one looks pretty good:

But it's no where near $100

Or this one for less than half:

I had a golf rangefinder which does this. It was accurate to 2-3 meters and lot more than $100. The accuracy was much better on courses where they use reflective marks on the pins.

What's on the other end? Just any object or an electronic device that you can talk to?
