Flour gold 7 seconds, Grains (5) 20 seconds, 14K gold Wedding Ring 14 seconds, 1/4 oz Gold Coin 60 seconds, etc. Not sure I agree with these times, I found much longer times so test yourself.

It is best to practice counting lock times with a visible target at first. Your rods might be sticky and may require you to wiggle them a bit to break loose the friction. Typically for me the rods rachet open, one step at a time. It is tempting to try and hold them closed so the practice can help you avoid this problem. Once you get this to work you can try it on a hidden target. Dell Winders said nine out of ten targets are insignificant size so this one is quite important to learn.
