sensitive and durable
Thingamabobbers are more sensitive for strike detection than a lot of other indicators because their round shape allows them to move easily at the slightest bump or strike. These stay on your line better than most indicators and are much more durable. These things last a long time and are virtually unpoppable. Its the best and easiest system I've found yet which is why they are the only indicators I use while fishing for myself or guiding.
