Underwater signal okay. Works better at depth (with less ambient noise).

Have to hold button down for over 10 seconds with surface signal to clear out water before a moderate whistle is heard - not great for panic situation.

Better than banging on a tank or an ordinary whistle

I bought this so as to combine the underwater "quacking" of my Aquatec Scub Alert with the ear splitting safety signal of my Dive Alert Signaling Device in on convenient package.

Well the "quacker" works great but the surface horn is a feeble joke. I put on hearing protectors and threw the dogs outside. When I triggered it I had to take off my earmuffs to make sure it was working. The volume is much less than a regular whistle.

I was excited to see this product because the previous attempt to combine surface and underwater signaling "the Dive Alert Plus" was also a bust. It had a great surface horn but a useless underwater signal.

This dog is going back to Leisure Pro.

Sure wish Dive Alert and Aquatec would build a joint product
