Light Weight and Comfortable too ...
Oct 31, 2019
Light Weight and Comfortable to wear. I am having a blast with my Mk Se7en so far. I ordered the Tec+ package with a couple customizations to get exactly what I wanted. The sales team is great about a custom package for what you want in your rebreather. Entire system was assembled in just over an hour ( I took my time and actually followed the manual). The paddle that comes with the unit is the same paddle as we had on the MkVI and works just as well. I chose to pair mine with the new M28 computer and boy is it a welcome addition. The menu allows you total control of your unit, all the tools you need to plan your system. With the upgraded CanBus attachment you can do all your pre-dive testing, pre-dive planning, in dive management and post dive reviews. The included GPS actually works, though I've not yet attempted to change the map on the computer. I find this unit to be lighter than the Mk VI making it easier to get on and off, and it's alot more comfortable even when wearing a light wetsuit. Great adjustability and plenty of Dring locations for all your accessories. Cleaning is about the same, all the same components and just as much need to disinfect the unit after your dives. I won't say theres a change in the actual daily tear down and cleaning from the MkVI but then even that wasn't that bad. This system is the right price, the right ease-of-use, and ready for fun. I played around with the idea of moving to a different unit this year, but in the end I stayed loyal to my favorite and I have no regrets. I love the mk Se7en and I'm sure you will too.
