Having a decent alarm can make fishing much easier. This is a set with remote control. There are four alarms and you can change the volume, tone and sensitivity using the controller. They are sensitive and can work in a low power mode so they will last a long tone. They have a nice range of tones that you can choose from so that you can set it to your requirements. They have a long-range as well which means that you do not have to worry about how far away you are. They all come in a handy storage box.
