So how do I make one or where do I buy one and how much does it cost?
OK- I know that they're illegal in public waters in Texas. Having worked for TPWD for a few years back when, I've seen them in the Game Warden's evidence bag. Still, for a private pond, it should be fine I suppose and for taking a census, it would be a useful tool.
I don't even know what they're called officially so I can't do a proper web search. Can anybody direct me to a source or at least give me a name?
