What is the average distance between the the eyes ( center to center ) of adult rats from the front?
Question for bulk rat shooters
- Thread starter WildKata
- Start date
The need to eradicate rats on my permission is how I got into air guns. Wouldn't call myself a bulk rat shooter, but I've probably destroyed upwards of 60 so far this year, and I would estimate:
Young rat (up to 7" body) approx 1"
Adult rat (up to 9" body) approx 1.25"
Mega rat (up to 12" body) approx 1.75"
Mine are all brown rats, and distance will probably vary by species.
Curious to know why you ask!

I have an idea percolating for an auto-ranging rat scope including DVR. Might have problems with one eyed rats though 
Percolation has reached the point of ordering a couple hundred dollars worth of parts and illuminators.

Oh, I see - image processing? Something like an Odroid XU4 sampling images via a little 1/3" CCD camera, driving servos on zoom and parallax until you're sampling reasonably dense clusters (focused eyes?), within a certain distance from centre to centre?
Sound like a lot of work!

It's been done and is on the market for $700. I hope a cruder, no servos approach will be suffiicent.

On further study I think I should have put the $200 in a jar toward buying the commercial scope

What else could you build with the parts you've purchased? I often embark on little build projects that end up morphing into completely different things!

On reading the manual the rangefinder in the commercial scope is not automatic - and needs the game to be measured in feet.

I haven't seen one in years, but Norwegian rats get as big as a house cat. I suspect their eyes are a bit wider apart.

Once they look my way; the nite site wolf and my .25 Bobcat do the rest. I use a caldwell stable table in back of my pickup like the prairie dog hunters but at night on brown rats at the grain silos. It's great outdoor night fun.
