Or, it really doesn't matter. Anything attached that makes "some sound" will work well.

Those inline rattles from Whisker Seeker and others work great.

Oh good question Holzer definitely following this post!!

I just ordered some from Whisker Seeker. I got the 5 pack. Gonna see if it helps

The versa 2 is junk. They leak and fill with water which makes the beads rust and quit rattling. Take a look at yours after running em for a month and I bet half of not all are rusted and not working. They were designed for guys that fish current in rivers.

OK, so far I've heard about Whisker Seeker tackle. Others?
But anyone make a rattle, or modify a lure for the purpose of creating noise on your rig?

I used glass beads before rattles were a thing. I rigged em like a popping cork. You can use the cheap rattles designed to put on a bass jig. I used to get Zara spooks and torpedos at garage sales and rig em as my rattling floats and those got slot of laughs back in the day . Now they call em Demon Dragons and nobody is laughing at em now. Fire water Marine and drift stix make a rattling dragging weight too.

I thought they improved them to be better
It was less than 4 bucks so if they stink that is ok

WS sent replacement versa 2s and they did the exact same thing. Takes a considerable amount of time to tie up 10 rigs and then half don’t work. When you fish with them Bentman, check em out closely after fishing with them. If they have water inside the rattle they aren’t rattling at all while fishing and are useless. If they leak they rust. If they rust they are useless. The regular Versas work good though.

I buy a ton of Whisker Seeker and I’ve had some issues with several different products but they always stand behind their products and make it right.

Live rattlesnakes..............

The versa two aren't really made for drifting for catfish anyway, unless you're in heavy current. In a reservoir the originals are what you should be using.

All I buy, for catfishing. Never had a problem, and their triple threat hooks are outstanding. Their shipping time is impossible to beat. Always ship out the day of or after, and I have it two days later. Just using standard usps.

Your lucky Z. I’ve been using them since they were a fledgling company and I can tell you from first hand experience they have had some quality control issues with gen 1 products. The first gen versas I bought 5 yrs ago came apart at the seems. Gen 2 versas resolved the issue. The first gen scales had a magnet on the battery door to hold the hook. Magnets and batteries don’t mix and it would drain your battery quick. Gen 2 scale no magnet. I’ve had eyes pop out of the gen 1 rods and I’ve had the skin come off one of the rods first time I fished with it. Versa 2 issue I gave up on after I realized they don’t work. All issues resolved quick and easy by their great customer service though. I’m still a satisfied customer.

I've only been using them a little over a year now, and I only get terminal tackle from them......and their mono line.
