yeah, gotta be careful using regular nets, even on the smaller guys. it's no fun when the stinger gets caught in the net. the more they move, they more it gets tangled.
scroll down to the fishing net section and theres tons to choose from. I got mine from the retail store, but they ship worldwide as well if you order online.
I tried a rubber net today to catch my humerosa.
Had not much room to move around, but i caught him
in 15 seconds and 10seconds later he was in a transport bag.
Great way to catch and handle a ray.
Thanks vamptrev for the info
