BUDGET. It is a shame that we always have to talk about the BUDGET. The price of bite alarms could range from several dollars to several hundred dollars. And the function and quality are very different with this price range.
Stability. If something goes wrong with the bite alarms, it is the electronic part. Therefore, the stability of the electronics is very important. It has to withstand the hot & cold weather and don’t fail. No one can afford miss a fish or loose an expensive rod.
Waterproof. For serious carp anglers, it is often to go fishing for more than one week. It is normal to encounter a rainfall. And it is very likely to catch a carp in the rain. So, a qualified bite alarm has to withstand a rainfall and moisture in air. Normal, the experienced manufacturers use a rubber seal at the plastic seam part and apply a layer of glue on the electronics. The water proof of battery lid is also very important.
Low battery drain. It is not good to change the battery of bite alarms 4 AM in the morning. The worst is the fish bite the hook, but the alarm does not make a sound due to low battery, thus the fish take the rod away. So, it is important when there is no bite, the alarm will go to the sleeping mode and minimize the power consumption. It is also good that the bite alarm can give a low battery warning.
Remote range. Modern bite alarms are all equipment with If the fishing site is cliffy, the carpers have go to sometimes more than 50 meters away to erect the bivvy. In this case, it is difficulty for the angler to hear the sound of bite alarm even when it is on its highest volume. So, it is very important to have a wireless receiver. When there is a bite on the alarm, the alarm will send the signal to the receiver. The wireless distance could vary due to different obstacles. Normally the anglers can not go to far, because they are not sure if they are still within the wireless operation range. In this case, it is important to have a receiver with range test function.
