I had the opportunity today to throw a $63 Betts 16' diameter cast net. I liked it better and caught just as many bunker as I do in my $210 Percy 20' diameter net. It was easier to load and throw.
Also since I had the Percy I had blue chew holes through it and almost lost it when I got it snagged on the bottom and broke several brail lines getting it un-snagged. I have been able to fix it, but would rather be have these problems with a cheaper net.
So I may suggest save the money and buy the Betts net, you can replace it three times and still be a head of the game.
It was Banana Boat Dan's net and he is going to send me the exact description of the Betts net and I will post it.
To be fair maybe if the bunker are deep the Percy may sink fast and thus do a better job.
