Having seen the sentinel in action in the flesh, it looks a nice bit of kit and i wish Kevin all the best with it.
Is it any better than my inspo vision?? IMHO no but as i have not dived it myself i cant really compare the 2 units for inwater use, other than on physical appernace and on paper specs, but does provide an alternate product for consumers which can only be a good thing.
Call me old fashioned but those 2 big 7ltr's each over the shoulder counterlungs on the inspo that everyone seems to slag do have some good potential ususes, just ask the kiss owners
