Dave King and the "THING"

Had a really great conversation with Dave today at the harrisburg show. I also got to see the "thing" in action... way to cool!!!
This is definitly the slickest thing for a long range shooter. Basically if you don't have it you don't have all the toys and gadgets that go with this sport. I would say within 2 - 3 min ( time taken for data imput ) you have your clicks ( or mils ) as well as windage adjustments you need to aim and shoot

Dave if ya get a min. shoot me an e-mail on how and where I can get one. Also gimme an e-mail address for your buddy that was along with ya.

Great talking to ya.

Re: Dave King and the "THING"

How about some more information on the "thing". It sounds interesting, what exactly is it, who makes it, what's the cost, and where can we find them?

Re: Dave King and the "THING"

Prime time,

What I do know is that it is like a hand held mini computer that you can carry around with a ballistics program in it. I was kinda busy at the show so I don't know all the details. I hope Dave gets home soon so I too can get ALL the details

Re: Dave King and the "THING"


Here's a link to a previous post about "The Thing". (Down the page a bit)

I originally found Peter Cronhelm's website and downloaded an Excel spreadsheet for ballistics. Peter and I got hooked up we modified it into something it was not. (Peter and I e-mail "The Thing" back and forth many times during the development stage (a never ending process). I don't think Peter had any idea of what he was letting himself in for when he agreed to test the critter each time I changed it.) [img]images/icons/grin.gif[/img]

It's hard to visualize the layout from the little Cassiopea screen you saw at the show but once you've seen it on a proper computer you can easily understand where things are located.

I does a lot of "magic" stuff.

There's the basic data entry section:
bullet weight
zero range
wind speed and direction
slope/angle value
range increments for the ballistics page
mover speed
MOA value
MIL value

(One thing we discovered at the show was that if you set the MOA value to the "click" value .262 for .25 MOA clicks the readout can be used directly as "clicks" rather than MOA. I think in MOA, some shooters think in "Clicks")

It determines:
Range based on GPS fixes
Range based on MIL value and target size
Windage and Elevation based on range, wind and slope, either hand entered distance or GPS. (Yes, the wind is calculated for the full wind distance while the elevation is based on "horizontal" distance.)
Elevation and windage correction based on "miss" value(s).

Lot's of little things.

On the main Ballistic data page there is also a section for entering known distance values and an immediate return of the MOA elevation adjustment from the zero setting, wind adjustment and mover hold-off in MILs.

This particular section also has a "Miss" section that allows the spotter to get a MOA correction by entering the vertical and/or horizontal distance in inches for the "miss"
The program will calculate the extra adjustment needed for a second round hit.

The other distance determination on the main Ballistic data page is to calculate distance based on MIL reading, supply the MIL value and the target size in inches and the program computes the distance and MOA adjustments for elevation and windage.

There a page for the standard Ballistics Table, good for creating a "click chart" when used on a standard computer. The increments for the page are controlled from the main Ballistic data page.

There's a Target Reference Point(s) (TRP) page the allows a shooter to input multiple target sites and one Firing Position. The computer will provide scope adjustments in elevation and windage for all the target sites. On the GPS determined position page, one TRP is designated the primary site and the computer "knowns" the wind values for all the other sites. I haven't worked a geographic elevation value nto this page yet and when I do the computer will calculate slope for all the sites also.


The Ranging Ballistic Computer spreadsheet is free. It requires Microsoft's Excel to run on a home PC. The Cassiopea and other handheld computers that have "Pocket Excel" will run the software also.

I'm going to develop a Visual Basic version that's stand-alone when I get a little more time.

ONE SIGNIFICANT DRAWBACK for the little handheld computers is that in bright sunlight the screen is nearly impossible to read unless you get the "backlit" version.


We can't guarantee first round hits.
We can't guarantee your batteries won't fail.
We can't guarantee your wife will be happy with you spending more money on another shooting thing. [img]images/icons/grin.gif[/img]
We can't guarantee the shed you'll be sleeping in will be big enough for comfort. [img]images/icons/grin.gif[/img]

This program is NOT as sophisticated as some others on the market or others that may be in development.

Re: Dave King and the "THING"

The THING is available free on my web page
Choose the Ballistics link. You can then download a zipped file called "Ranging Ballistic Computer" which includes the THING and a small instruction page. This file was saved as an Excel 97 file so any older excel versions may not be able to read this file.

The THING works great at home or in the field. My first deer kill was done from Thing data and I have used the THING in the varmint fields.

I tested the THING extensively in the field even though it was hard to keep up with all the changes Dave made to it. This thing works and it is really fun to use.

Dave, if you ever make any substantial changes, send me a revised version and I'll put it on my website.

I would argue that the THING is, in many ways, more sophistocated than many current ballistic computers.

For best results in the field, make sure to get a handheld computer (capable of running pocket excel) with an LCD screen so it is visible in bright sunlight.

Re: Dave King and the "THING"

That's a cool little hard working program you got there. I just used a few minutes ago and compared it to what I have been using. Looks great. I've been using Pejsa's program and that works great also.
I like all the other feature you have on yours. Like gps and mil. And multiple target ranges. Cool, Way cool.
