Yes mate of course, The easiest way for me is to explain the fishing situation.
Fishing at 120-130yds with 15lb line straight through and 3.5oz leads, helicopter setup on tubing with 4" braid hooklinks.
Line tight but not bowstring, using Solar Quiverlock indicators.
I had already had one fish from the area and lost 2, the runs being a bit of a funny lift and drop, lift and drop, developing into a run by the time I got to the rod. I was stood next to my rods chatting with a mate who was fishing the next swim, and he looked down at my tip and said, "You have a take" so I looked at the indicator and it was juddering slightly while the line at the rod tip was lifting and dropping slightly.
There were no bleeps from the alarm yet the indicator and the line was moving slightly and also vibrating and juddering. After watching for a few seconds I picked up the rod, wound down and struck, nothing.
The next morning this happened again as I was sat over the rods watching, and I struck immediately and was into a fish.
I'm convinced that had I been using vibration alarms I would have had an audible indication and I'm just as convinced that the fish was just sitting, trying to get rid of the hook. This was in France on a very pressured lake with big fish, I had 7 takes (That I knew about at least!) and landed 3 fish all over 40lb, so we are not talking about pasties that can't move a lead!
