I am unable to take a photo of my “prod” as it is at home and I am in the office right now. I might attempt to draw one out and see if I can convert the drawing to a file that can be shown on here if I can figure out how to do it. I can make PDF files of anything but converting a PDF to a jpg?????????
All I did was take a heavy gauge steel wire somewhere areound 1/8″ to 3/16″ diameter. Actually it was the wire frame from one of those stupid political signs somebody tossed in my front yard. I just took the wire out and straightened it. Then I took an old plastic handle from an old Minnkota trolling motor that had broken off, filled it full of hot glue and stuck one end of the wire into the handle. A wood handle will work just fine or any other non-conducting material you can think of. Then I took the plug and wires off an old fan that had died. Then I took the hot wire and soldered it to the rod right below the handle. Then I wrapped the connection with black electrical tape snubbing off the ground wire. You will only have one wire (hot) connected to the rod. When you push the rod in the ground you will feel a buzzing or slight vibration in the rod. That way you’ll know you have the right wire connected. My prod is somewhere around 36″ long including the handle. Sometimes I only have to push it down a foot or so and other times, when it is dryer, I push it down as far as possible. You can use any steel rod to make a prod. One of the guys I work with used a length of 1/2″ rerod. I think that might be difficult to push down in dry conditions.
You do not have to unplug or pull the rod out to pick up crawlers. Just make sure you are wearing shoes and it is not pouring down rain. I got a feel of it once or twice while picking them up wearing sandles in the wet grass when my toes got a good contact with the ground.
I try not to leave the prod in any one spot for longer than 10 minutes. Usually most crawlers that are going to come up will be up inside of 10 minutes. If you leave it in longer you can damage the crawlers still in the ground. I’d say I get about a 3′ diameter area covered every time I move my prod.
