When fishing for carp, you may at times have quite a wait between bites. This means that you may get distracted and be looking around at what else is going on, perhaps checking your phone, reading a book or even having a snooze. It could be that you have several lines set up to keep an eye on. Either way, you may miss a bite when it comes along and therefore you could find a bite alarm very useful. They will let you know if a fish is interested in your bait and you will be able to get ready to see if you can reel it in.
