I've got 2 carp landing nets: a Fox Warrior net which has had the mesh replaced a few times and a Rod Hutchinson Sceptre net, both in 42inch.
I've spent more replacing the meshes over the years than the landing net originally cost.
For years I lived with just one, but a few years ago came up with the idea of one on each side of the swim, so I could always reach one without, in theory of stepping around the rods to grab it.
The 2 faults, they don't match, not that I really worry, and the second is many runs now seem to come on the middle rod...
I can't remember who it was by, but the original Springlock mechanism landing net I do miss. I borrowed one for a while back in the early 2000's when I had a load of gear stolen.
