Love my Mk3i

Bought for scuba diving but died so much more. The health monitoring and scabs computer will be used a lot. So many features was overwhelming at first but learn a new one every day, it gets easier. Started using for multiple other exercises and sleep monitoring.

Great features but no connectivity to SSI app

I purchased this mainly due to the smartwatch + dive computer capabilities. Its hard to forget your dive computer when its already on your wrist! I also love the connectivity with the InReach Mini! This produces an added safety feature for ocean dives! As i swim and do other exercises, the other sports/workout features are an added plus. I love the air integration with the transmitter as well! The only thing that disappoints me is thr lack of connectivity with the SSI dive app. Other brands have easy bluetooth uploading into the SSI app, which makes logging your dives for SSI certifications and awards a breeze. I ended up buying a cheap extra dive computer to accomplish the uploads to the SSI app. In my opinion, this is not something you should have to do after spending so much on the MK3i. I have not yet used the underwater communication or maps yet on this watch but am excited to test out those capabilitiee on an upcoming boat dive trip!

A dive computer that I wear everyday

This is a good looking dive computer that I can I wear everyday. It offers significantly more capabilities than my other bulky dive computer. Battery life is very good.
