However, the not-so-recent case of divers going missing of Tioman waters actually prompted me to get it soon. The issue with these safety devices is that it's always too late by the time you need them. So getting it sooner actually gives me better utility since I will get to use it sooner (and hopefully more often!)
By the way, if you are interested in how it works, head over to http://www.nautiluslifeline.com/
With the Nautilus Lifeline, even if you lose sight of the boat you still can communicate with them!
I gave it a try during my last dive trip. The diveboat, Tinggi Harapan, was monitoring channel 09. It worked straight away after setting the correct channel. The most useful purpose during the trip was when we used it to comms the boat from Aur, during their night dive, to find out their status. The dive boat was out of sight, but we could hear them loud and clear over the radio, and even chit chat with them. I guess this radio can serve as a land based station instead of just being an emergency device. No more wondering when the dive boat will be back if you didn't go out with them. Just give them a comms over the radio. How wonderful! hahah..
