I have no idea if I am describing this properly, the only thing I know to describe it is a caddy for the pole on on the seat pole underneath the butt seat on the front of a bass boat.  Here are two examples:

These are really the only two I can find on the market however I have seen two WAY better examples in person.  The one I liked the best was kind of a 3/4 circle that held two drinks, had a notch for pliers, hooks for misc stuff, a retracting cable for a golf towel, recessions to organize tackle, etc.  Both times I asked the fisherman where they got it and they both said they had gotten them a long time ago and could not remember where.

These two on bass pro are okay but the reviews say they are flimsy and/or too small for practical use.  Both the ones I saw in real life looked to be designed by a bass fisherman for bass fisherman.

Anyone know where a better version of this is available?

Thank you.

Thats pritty kool.

I just bought the Handie Hold-It Supply Caddy.  It will not hold a Gatorade bottle, so it is of limited use for me.  I'm still in the market too.

I know someone on here has a better solution.

The one I saw in person was the mac daddy of seat caddies.  It was definatly manufactured and not homemade.  I have googled for it to no avail.  I am probably just searching the wrong term...I don't know to call it other than a drink holder or caddy.

I bought the arm shaped one shown in the first ad.  It was very flimsy until I bolted an aluminum plate underneath the section nearest the seat pole.

I was actually thinking about the handi holdit but will mark that off the list given the reviews from others so far.  

guys this ain't that complicated,make your own out of a nice piece of oak like 10x4 ,you can drill or cut for cup holders and so on for the pliers and a hole for a tray and use a glad tray that you buy sandwich meat in stain it,paint it,varnish it or what ever then screw it to the bottom of the seat here an example and i think im making one for myself
