Just above nickels in the pull-tab range. The stock coil covers the ground well.  

I try and show all that in every video I make.  I'm not taking away from anyone making videos.  It takes a lot of time, money and effort.  Sometimes I come home with 8 hours of video and I then have to watch the whole thing to put the best clips into a 10 minute video. 

I envy the sites this crew are able to secure. All seem like pretty darn good hunters as well.  But I couldn't get any feel for the machine with so little live digs.   I like more machine and less coins on plugs. Probably just me?  Nice videos nonetheless. 

Great news!! This is Whites best kept secret.  It's a great machine,  Now 100$ less!  Sweet.

I got that Coin Popper at O'Reilly Auto Parts. It's the Titan brand gasket scraper with a square shank. I then ground a radius on the edge then sharpened it.  $7.00   But there are other brands of scrapers that will work.  Ebay has the exact Titan gasket scrapers too.

Thanks Steve for showcasing my video!  I never knew my gasket scraper would get so much praise! LOL. 

It's a Johnson 4000 GPH pump.  There are no pressure specs.

I have some fittings in hand for a mock up.  I have yet to buy the pump as I'm undecided on how to tote the battery around?  I first though a light weight li-ion battery in a back pack?  But the cost is too high.  I then thought a sealed lead lawn mower battery?  Those are about 24 to 30 amp/hour and 25 pounds. I think too heavy for a backpack?  So now I think I'll float the battery and use that to suspend and support the collection box?  Also if I float a battery it might as well be a larger marine battery that will run the machine a long time? So now my thoughts are on the power supply.....  I don't want to depend on a Kayak or Boat to bear the weight of the battery either.  I'm open to suggestions...............................................................................Oh the pump is 12 volts and rated at 15 amps. 

Thanks for the link.  I see that they have clear hose too.

I like the shop vac hose idea!  I can easily get that in 2 inch.  Plus as stated there are adapters already made. I would have to make some type of rigid arm to hold the hose. Maybe 1 inch PVC?

It doesn't look like that dredge has enough power to suck a bullet?   But gives me some hope.....

Let's talk about hose, and nozzle size?  I would think there must be a good ratio of nozzle inlet to pipe size to reduce clogs?  My target size is bullets.  Here is a .69 and a smashed canister ball.  These would be about the biggest lead pieces I'll suck.  Now it's got me thinking about coins!!  Yikes! Should I make the nozzle big enough for a Half?  I haven't found a half in the water though...... I first though this was going to be a simple project - now it's grown bigger than expected!

I just wonder if it will have enough power to suck big lead? 

Cheap is good especially if you don't know it will work! LOL  

I need flexibility between the wand jet.  Is this the type of tube I can use for this application?

I would have the wand in sections so I can add or remove enough to keep it all under water.  The shallow bullets can be grabed by hand mostly except for the ones stuck deep in a crack.  I'm after bullets too deep for most detectorists.  I just wonder if it will have enough power to bring a .69 of from the depths?  I was thinking about using a 1-1/4 wand with the end contoured inward to 1 inch.  Is that enough difference in size as not to plug often with rocks?  Should I bump to a 1-1/2 inch wand with a 1 or 1-1/4 inch entrance?  Do you think it would be better to run one 4000 gph pump or have dual 2000 gph pumps feeding the jet from opposing sides?

I can make a better version of this out of plastic.  It would seem this would work better putting the pressure feed in the end at an angle as to swirl the water? Yes? No? 

That's what I was hoping for - to have a long plastic wand to suck in unison with my wiggling coil.

OK.  If the whole unit is underwater and everything equal would it be better to put the jet down in the head or up toward the box? 

I could have the catch basket just under the surface.  I'll have to do some figuring on battery consumption.........

Some of the lead I find are a lot smaller than a dime.  Was thinking 1/4 mesh to catch 32 cals.  I would like to catch ALL the lead so I'm not just re-finding the same piece.  Maybe just run to to a floating basket?  At a slight angle I figure the total length to be 7 feet?

I ran into this system.  Looks like you could use pipe instead of a box and end it in a simple mesh wire catch box.

I see your suction jet is mounted at the upper end of your rig.  That is what I was wanting to do with my electric machine.  I know if I went with a gas dredge my issues would be solved but want a quiet running machine. I would entertain buying belt drive pump and slapping a 12 volt permanent magnet motor on it.  But I haven't seen any "dredge type" stand alone pumps?  Have you?
