I'll be watching this post because I plan on building one soon as well.

is it getting that hard to catch sand bass? wow! I like the serenity, you must like the noise? fish the bridges, they thump

I like the serenity also. I like catching a lot of fish more though. Some of us put our Thumper's in a compartment below deck where we can barely hear it while it's running. Win win.

Jbobo, sent you a PM

Could you just record it on your phone then play it on a waterproof microphone dropped over the side? I've never heard of such a device before this thread.

Hydrawave has a thump module, I don't know if anyone here has used it.

I had a Hydrowave with the thumper chip. That was not even close to the thumper.

Can i get a list of the items you bought so i can attempt to copy you ?

I just built a thumper after going with an awesome white bass guide in central Texas. He swears it helps concentrate the fish under his boat when he spot locks ontop of a school or is off a little bit. It "picks up the slack" so to speak by drawing them in by curiosity of their lateral lines sensing the rhythmic vibrations of the thumper.

Supplies:
I bought an orange storage container from Academy (the bigger taller of the two containers). Costs $14.

On Amazon i got the motor and control knob for under $30. Look up "190 rpm 12Vdc" and it should bring up a generic car seat motor. It's about $17. Then get a RioRand motor speed controller. This will allow you to control the speed.

You can make the thumper with a hammer like a dead blow hammer or if you have some tools like I do you can make a heavy rod go up and down in a pipe.

I attempted to make a short youtube video to give you some ideas.

Scientists have researched fish sounds since 1st world war. Many fish make a thump sound when feeding. Other fish hear the sound and know to go to the sound to get a bite. Just FYI

Thank you!

I would be very appreciative for this information as I am interested in building a thumper. Bob Bevill mbbevill@att.net.
Thanks

Ooops sorry, I got better at YouTube and went back and added pics of supplies and few key pieces and it changed the whole web address.
