The Duo Alert is a combination of two very effective signalling devices, one for underwater use to get your buddies or your dive group's attention, the other for surface use to signal where you are (for example to boats or people on shore).
The unit is light weight and compact (so great for travelling) and has a volume of up to 125 decibels!
