I'll take that beast and the ABS test cannon. I'll be fun to compare them side by side with golf balls and paper towel wadding in the 2 inch barrels. Yes, I'll be taking the large one, the ABS cannon and the Marshmallow cannon. I'm also taking a GPS. I'll mark all the shots with the GPS. I'm heading to the hardware store now for sprinkler flags. 2500 feet of clear field for testing. I already know the range of water bottles and tennis balls. Time to find out how far golf balls go.

Sounds awsome, can't wait for the results... my video might have to wait until tomorrow, because I can't find a camera man yet, but there is still a chance... if not tonight, then definitely tomorrow. Good lighting in the morning!

New video for you guys. The 471 yard shot was done at 60 psi.

Nice job. Great Video. Do you have a capture of the launch and landing site from Google Satelite view?

I still have some GPS stuff to work out as my GPS went from feet to miles as we started measuring shots. I do have a collection of photos for now until I get the distances ironed out in feet on the laptop TOPO map.

We had a nice morning at the farm and then got rained out.

We did a golfball shot at 50 PSI to see if we could find it before it started raining hard and steady. GPS marked it at .227 miles. The rain also killed shooting the ABS cannon and higher golf ball shots. I am very certain that the cannon shoots golf balls well over 1/4 mile at 100 PSI. How far, I still do not know.

The field is .45 miles from the launch point to the fence at the far end of the field.

Ahhhh that stinks, you could totally clear a quarter mile at 100 psi! Too bad you couldn't shoot anymore. I didn't have a compressor at the lake, otherwise I would have gone higher. When I get my new pump and rebuild the new chamber for mobile shooting I will do some 120 psi shots.

I took the time to post the GPS coordinates of each shot and take a screen cap, then with a photo editor I copied each marker onto one screen shot aligning the background of each edit for precise location. The composite photo is below.

The numbers are random spuds and apples from both the Marshmallow cannon and large cannon with the 2 inch barrel. The kids got turns shooting the marshmallow cannon at lower pressure. Not all shots were measured.
A whole apple was launched from the 3 inch barrel at 100 PSI to see if it would fly better uncut. It did and was the farthest shot of the day. No wadding was used and it was loose in the barrel.

A golf ball was launched from the 2 inch barrel with a paper towel at 50 PSI and one was launched from the marshmallow cannon at 100 PSI. That was the only two golf balls launched before we got rained out. I still need to find all distances in feet. I am checking my various GPS programs and settings to get this. So far, they convert to miles at 0.1 miles.

If the OP is getting 471 yards on 60 PSI and I am getting just short of 400 yards at 50 PSI, a quarter mile at 100 PSI should be no problem. I think the 471 yard shot had a tailwind. That did clear 1/4 mile.

The wind was to the west, and I was firing to the north. That's why it landed in the campground instead of in the water It had a nasty curve in the air though! It was awsome. Pretty impressive results there, especially the golf ball from the marshmallow cannon. 200 yards on that little beast? Nice job! I wish I'd put some other barrels on Superna, just to see what kind of range I'd get with some other vegetation
Can google maps or Earth calculate distance between points by itself?

"Can google maps or Earth calculate distance between points by itself?"

Sadly, no. It tries to give driving distances on nearby roads.

I'm using Back Roads Explorer on another computer to measure distances between points.. It is a Windows program. I'm running Ubuntu on this one.

Er - what? Google Earth has a ruler tool. (I don't think Google Maps has though.)

Select the thing that looks like a little ruler (just to the right of the mini planet symbol on the version I'm using - which I think is current, but not sure), click in one place, click in the other, and it'll tell you the "as the crow flies" distance between the two points.

Just beat me to it..(I use Google earth's ruler tool all the time) And lol, I'm getting jealous of these 1/4 mile shots, my pneumatic is only sending a battery around 150 meters.

Hmm, I'm going to have to install Google Earth. Can you get feet instead of miles?

In the meantime, I'm going to try meters and Km and see if that works better.

Feet, yards, miles (nautical miles too, if you want), metres, kilometres... even, questionably, centimetres and inches.

You probably won't be wanting for choice of units.

Here is what I came up with using Google Earth.

356 yards for golfball at 50PSI. (.20 mile)
424 yards for apple at 100PSI. (.24 mile)

I'll PM you the numbers right from the GPS. The launch site is the next big tree to the south near the gap between the trees.

But here is what you sent me. Updated!
