Check out my home made coin plugger

[BADBAJA]

This thing leaves such a professional look after you pop a coin from 6+ inches. I used to have a cheaper caulking gun but this new caulking gun is smooth and very powerful. Pumping is easier also with the nicer gun. I checked the ones at the park I did last week and they look clean. No dry spots. It rains here often.

Hope I'm not infringing on any patents.

materials;

1 caulking gun. Use quality unit $8 or more
1 3in aluminized exhaust with serrated teeth on one end
1 rear axle from bicycle with stunt pegs. (piece of pipe will be my next step)
1 big washer to push plug out.

Assembly will vary so have fun

Note teeth

Plug put back

Not sure what WTO means.

It's really smooth. Been plugging a while now. Bulky though

nice invention!

I made one a little smaller than that a couple years ago. It is a great tool for planting a coin test patch. The down side of it for hunting is you really need the a nice turfed area with fairly moist soil underneath in order for it to work and your pinpointing needs to be accurate. Does not work well when the ground gets dry or there are a lot of rocks. I still have it and use it once in a while, but my preferred extraction tool is my trusty screw driver.

Very nice setup, I like your inventiveness. The caulking gun is a nice touch. Sometimes those plugs can be a bear to push out of the plugger. I bet that setup makes it pretty easy.

This is one I made many years ago. I used SS photo devolping tank for the barrel. I think it is 4 inches in diameter.

Nice. 4" in is a monster

You have to pump some iron to get through the dry stuff. Used it today even in some dry rooty soil and it's a beast. I even double plugged it about 8 inches of dry and it struggled but if I released it then pumped again it pushed it slow but it worked. I also hit up a really well manicured lawn and you could not even tell I was there. Thats hard for me with a screwdriver in a park. If anyone asks I am going to tell them I got the idea from the golf coarse plugged. Might even make a putting green out back. Lol

I've seen a couple of the caulking gun pluggers now and yours looks to be the better of them.

I made a long handled one and like others have said in REALLY dry hard soil these diggers get hard to use. Case in point, this past summer my brothers and I were hunting a site and the ground was REALLY bad, dry and hard. I had already used my digger a couple of times on other hunts and it worked like a dream! I could get the coin depth plunge the digger in the ground, give it a twist and on a good number of digs the target would be right on the end of the plug or laying loss in the bottom of the hole

So, I thought this would be a good place to use the new digger! Wrong! I couldn't plunge it more than a 1/2" so I got the bright idea to lean over it with my weight and just twist it back and forth and let it cut a plug! that worked great! but it became impossible to get the plug out if the digger. The digger has a 1/2" stainless guild rod in it, the ram is a full 1/4" thick solid plate! I pushed on the foot peg so hard that I bent the guild rod
Later I had to chip the plug out of the digger. So, I finished the hunt with my hand held digger but even with it some targets had to be chipped out of the ground. So, a digger like this works, but not everywhere, or not if the ground is really hard. Just tonight I managed to take a long 3/8" drive extension and put the end of it in the ram's center hole and pry it back straight, man was that hard to bend.
And it has already been determine that long handled tools like this should not ever be used in parks! But for some places this tool is a very NICE tool.
Notice how when you look down through the top you can see the center hole in the ram? that was a plan. When I use this tool I use a bright colored golf tee as a pin point marker, take the digger and set in over the marker with the tee through the sight hole and bingo! perfect!

These are really cool. I can see where, in the right soil, they would be great to have. Now, something else to build What's life without goals!

My long handled plugger works in MOST soil! but if its mid summer, Hard and packed the kind that you really can't dig with anything then these just won't work! With my soil knife I could chip and scratch my way down to the target, the plugger needs to plug!

I have two brothers that detect so I've made more than one!.

Markcz I seen your foot powered unit and really like it and even thought of doing a foot-caulking gun hybrid. Thank you for the pics of that unit. The caulking gun is working flawless. I just have mine barely threaded in to hold the gun. They make a larger gun just like mine for just under $20. The action is so smooth it is a very solid gun. I have had 8 inches of dirt in that badboy and it just pushed right out. My 9 year old boy can get most of the plugs out of the pipe with the gun. Gonna have a you tube vid soon.

That's a great design Marc!!
