A Push Pole is what a pole for punting is called.
Push poles in the US are usually sold in sporting goods catalogs for duck hunters.
I couldn't find one for a reasonable price online - the better ones were over 100 dollars.
So after looking at what was available online, I figured I could make my own first and see if it did the job.
I looked at all the extension handles available at Home Depot and settled on
a 6' to 11' handle from Mr Long Arm. they make many different types and lengths, the one I choose was 6 foot of heavy yellow fiberglass with an aluminum extension which LOCKS using a positive latching method instead of a tension screw. I had a hard time loosening the screw type in the store...out in the boat with wet hands I don't have a chance.
Push Poles need a 'foot', most commonly they look like a Y or a T, like a polo mallet.
I planned to make it from PVC of a similar diameter to the rest of the pole.
I also got some Stretch and Seal Silicone sealing tape (which has no adhesive of its own) because my T section doesn't fit snuggly on the butt end of my pole and I don't want it to fill with mud and water.
