A little game of range estimation

[Rumblingdwarf]

How far away do you think these people are?

Spotter is a Bushnell T-Series 15-45. Reticle subtensions are half and full mil.

Spotted on top of a mountain behind my house.

 

[Tokay444]

I come up with 9,000m-12,000m.
It’s tough, because of the course subtensions, and the reticle being nowhere near them.

 

[ForgeValley]

I'll go with ~7000 yards.

 

[ForgeValley]

I come up with 9,000m-12,000m.
It’s tough, because of the course subtensions, and the reticle being nowhere near them.

And we don't know how tall the person is and I don't think we are seeing all of the guy standing. I estimated 6' and .28 mils.

 

[rtB]

Out of range.

 

[Choid]

I have him at 1.7m and .15 mil. So 11k or so. Meters.

 

[Rerun7]

Pfttt.. that guy is clearly 9,267.4 meters..

 

[Rumblingdwarf]

Pretty impressive for a $500 spotter

 

[opeagle]

Lots of light helps. Oh and 10,000 yards give or take a few.

 

[rhsc]

I'm guessing he's about .1 mil tall, so a little under 20k yards or 11.36 miles.

Pull out Google earth and do a map measurement. It'd be more accurate.

 

[TriggerJerk!]

Too far! With lots of measurement error and height assumptions.

So ~0.125 mils (1/8 mil) for a ~1.73m average human.... = 13.8 km. Is that Snowbird?

 

[Pbgt]

ya might want to lead them just a bit, probably hiking @ 1.5 mph on that terrain.

 

[nutation]

Low range estimate: 5'9" tall, 0.25 mil subtension -> 7,000 yards
Medium range estimate: 6'0" tall, 0.2 mil subtension -> 10,000 yards
High range estimate: 6'3" tall, 0.15 mil subtension -> 15,000 yards

 

[aamity]

Far enough that I'm not worried about him shooting back. Time to call for indirect fire.

this...
use a topo or GPS
right tool for the job
they are on identifiable landmark

 

[Steel head]

9134 meters

 

[Hesperidins]

They are clearly from here to there.

 

[Rumblingdwarf]

Doing my best to find that main peak on Google maps I came up with 5.8 miles. Looks like the estimates closer to 10k yards were more accurate.

 

[FLIGHT762]

They are clearly from here to there.

And somewhere in between.

Doh...I was kinda close...I came up with 7.6 miles trying to mil it a week or so ago shortly after it was first posted...I mean hey...what's plus or minus a mile and a half lol

 

[AKMarty]

16.6k yards

Well, I was way off. My original estimate was based on simply eyeballing the close-up shot of the climber on top of the peak. Just now, I copied that image, doubled its size, rotated it slightly to get the reticle stadia closer to true vertical, then measured everything in pixels. Still having to guess at the height of the person standing, but my new calculation (based on the person being 0.196765 mils tall) comes to @ 9,879 yards or 5.6 miles which is a lot closer to what you determined using Google Earth. Taking careful measurements definitely yields better results.

So my guess on the low end was within a few yards. Wonder what my danger space is out there.
