How loud is the underwater signalling device? We do survey dives where we can be up to 15m apart; right now we use the Scub Alert, which is sufficient for that distance and then attach a separate Dive Alert for above water, but that's too bulky so we wanted something more streamlined. But it needs to be loud enough underwater.-
Sorry for the delay but I was on vacationes.
This device works very good and the soun is very strong for me, and definitely is one of the best I ever used, you wont be dissapointed
It's load enough but you have to let others know what sounds like when you start diving because most people won't know the the sound is, their are use to tank bangers and it takes time for them to respond.
I've used this at distances of 20-25 feet without a problem hearing it. However, have not have the opportunity to need to use it for longer distances. Seems like I should test at longer distances next time I'm diving.
Sadly, it's not that loud. We have difficulty hearing it beyond 5m.
I think its pretty loud but I'm never that far from my dive buddy. If u already have the dive alert I would suggest just trying it and see. Sorry I wasn't more help.
If people are in tune and know to listen for the sound it can easily be heard 5-10 meters away, likely up to 20 meters. It is about half the volume of a tank bang with a knife. Sounds like a duck quack. Above water its super load and can be heard on a boat a half mile away with its diesel engines running.
Hope this helps.
This unit sound identical to the Scub Alert - easily heard at 15m.
It's just as good underwater as the one you have now.
