Tennis Ball Cannon - 2.0 Piezo Launching System

Wow! I like it. I decided to use Arrid Extra-Extra dry deodorant for the propellant instead of hair spray because 2-1 second sprays is perfect and it only leaves a powder residue instead of glue behind.I added a open fishing reel with 50lb test fishing line. I also modified 3 of my tennis balls by adding a cable to them and adding 3oz of weight so I now launch a 5oz tennis ball over tree limbs so I can erect Ham radio antennas.Another thing it is useful now that it is modified to go over trees is I can now cut high tree limbs. Just fire the weighted ball over the limb you want to cut, then attach a rope to the ball and pull it back over to the ground. Remove ball and attach a chain cutterhttps://smile.amazon.com/gp/aw/d/B096GBJQ25?ref=ppx_pt2_mob_b_prod_imageAnd trim any limb you want. LolReally, it works great!

If You've never shot off a potato gun, this is as close as it's going to get without using an actual potato. With a little dry deodorant, it can clear tennis balls over my 5 acre field. But it also sounds like someone's shooting a gun every time I do so. Also do not advise this if your dogs are scared of loud noises, because like I said this thing is definitely loud. Aside from that, it's a freaking blast. No pun intended

This unit works well and really launches a tennis ball far. Just be sure to clean the threads for the end cap when you are done using it. Hairspray will make it hard to get the end off the next time you use it if not cleaned. Great product!

Came with igniter in pieces… fixed it, but could never get it to shoot (tried many of these and that’s a personal problem for us), but the igniter keeps falling apart… pretty risky to use cheap stuff with something that causes an explosion to fire tennis balls…

This thing is legit! I've always wanted to build a potato cannon as a kid, but never got around to it. And now I get to enjoy something from my childhood with my son (and I don't have to clean up potatoes, since I opted for the tennis ball cannon). It's built solidly, it shoots really far and it's a blast. While I was playing with it in the park with my son some people walking their dogs asked about it, makes sense since dogs love playing catch with balls. My wife wasn't crazy about it at first, but after a while she asked to shoot it and had a blast. This inspired me to try and build a potato cannon with my son, since I like to use my hands. After we built it we'll have a competition to see how they compare.

Works as advertised. This cannon is excellent if you have at least a medium size yard. Mine is 5 acres so my Golden Retriever and Whipador are in fabulous condition from chasing tennis balls at roughly 250 feet.Warning: Don't "poke" the trigger/button with your finger as I did. I suffered a significant thumb sprain from the kick.

You have to be exact on hair spray for maximum height. More is not better

Dog loves this and so do the kids. Great quality and product. Works well.
