Hi. You won;t regret getting the leak sentinal. To be honest I prefer the leak sentinal over the Nauticam unit (I currently use Nauticam as it came with my new gear) - primarily because it can be set well before the dive and put into standby and turned back off without opening the housing. With the nauticam you must open the housing to turn off the switch which can mean the unit stays on longer than you want.
I am more than happy to recommend the creator of leak sentibal --- Miso --- and his product, I live in remote Vanuatu and frankly Miso has been terrific to deal with ! Cheers John
