Amanda to set nets up over water so you don't have to get wet, I use a version of the swinging nets Terry Reardon taught me. It works really well.
Basically you need pole holders you can hammer into the ground. Terry has special custom made ones but I just use 45cm star pickets with black poly pipe lengths wired into them.
The aim is you put your net up over the water, with 2 pole holders, but one end of the net can swing. When you set up the net, pick the swinging end and walk the pole and net taut until it's accessible from the bank. Then you hammer another extra pole holder in there. Then whenever you get a bat in the net you can grab that end swing the whole net up onto dry land secure it in the pole holder and extract the bat/s. And swing it back over the water to reset... Make sense?
Works even better with two nets both swinging.
I've attached some dodgy sketches which I hope help explain rather than confuse.
Cheers
