What's the longest thumb driven syringe pole you can get and where can you get one

The ones that I make are 4 foot. Plenty long, make them too long it is more difficult to make an accurate delivery. I make a 2 foot break down model one also that I carry on my ATV. I put it a pvc tube to carry it and components.

I built mine out of one of those expandable paint poles.

Tomahawk traps sells one that is 72" for $100.00.

Im a journey man toolmaker. I couldnt find exactly what I was looking for so, I ordered material to make my own take down model. May make a few to sell.
3,6,9' model or a 4,8 ' . Not sure which yet. But thanks guys for the suggestions.

Keep in mind the length limits on shipping UPS and USPS is 4'.

I was at the Fur Takers convention in Iowa a couple years ago. A father and son had a skunk pole that consisted of two 3/8-inch Fiberglas rods held together with what I’d call a couple plastic figure 8 clips. A syringe was glued to the end. They wanted ~$25 for it. The material cost looked to be <$10. I didn’t buy one but I remember the design in case I need to build my own

I have never used one but understand the concept. Couldn't I simply epoxy the syringe plunger to the end of a pole or fiberglass rod? Sort of a "jab stick"?
Load the syringe itself, insert the plunger, then stick the animal?

I've loaded a syringe and duct taped it to the end of a rod many times. Knock on wood, I have never been sprayed.
