A Bottom contact sensor that is mounted on a weight suspended by a rope skips along uneven ground. A Scanmar Bottom Contact sensor, on the other hand, has stable bottom contact. Yet we have learned little by little that this is not the most important thing. Yes, bottom gear having good contact with the ground is crucial to good catches of bottom fish. Obvious, you say? Yes, but what is good contact? Well, it can vary.
To give a rough description, we can say that it is appropriate to have hard contact on the bottom when it is hard, uneven ground with a lot of noise. Conversely, it is appropriate to go easy on the bottom when bottom conditions are such that the gear can dig into the surface. But not even this explanation is complete. Demersal species are different, some stay well above the bottom while others burrow down. Moreover, fuel is an item that should not be forgotten. The harder the bottom contact, the greater the towing resistance and fuel consumption.
What makes Scanmar's Bottom Contact sensor so useful is the precise angle measurement it provides. The sensor measures the angle in the same way as Door Angle sensor. It is therefore easy to detect how hard the gear goes in the bottom and when it has lost bottom contact. This makes it easy to fine tune the gear and adjust how hard the bottom contact is based on the species you fish.
