Neatly, thanks for asking...
Maclean weight net. Pair of strong magnets, and a coiled lanyard
Each magnet on a split ring. One half of the pair is attached to the D-ring on the rear shoulders of fishing vest.
Other half of magnet attached, with cable tie, to the hoop of the landing net. Magnets come together, and net hangs handle down from my back. One end of the coiled lanyard is attached to the handle of the net; the other end clips onto the left side of my vest. after releasing a trout, i can drop the net and it'll float around.
it's all neat and works well. Slight fiddle lining up the magnets behind me after using the net, but do-able.
used to my net hanging handle UP and net down - man, that would get tangled on everything!!!
