Part of the routine on my Game Boats has been to check everything that involves catching fish. That includes checking lure rigs regardless of whether a shop, mate, or you make them. It also includes checking rigs such as pre-made ones on the new range of Pakula Lures. It's better to find the problems if any before you hook-up rather than after.
01: The Full set-up to check a rig
02: A snap should be attached to something solid and then snap on the leader.
03 : The hook should ALWAYS face away from you (or anyone else) to minimise the chances of getting hit by the hook if the snap loop fails. Here we are using a set of scales to check the rig. You can also use your index finger around the hooks or anything else you want to.
04: Pull on the rig to make sure that it will hold together under the pressures you expect to use on the rig.
