I dove earlier this year with a guy for week that had a sealife. It took pretty good pictures, but comparing side by side with my Sea and Sea, it appeared the biggest difference was the strobe. We were able to fit my stobe to his and it made a big difference for a dive. The advice my dive shop gave me was, buy the best you can afford and make sure that you get the accessory’s you want. Good advice, since the discontinued mine 8 months after launch.
Good luck in your choice.
