Hi, I am considering upgrading my dive computer. I have the i300c and it works fine. I have dived with buddys who have the shearwater perdrix ai and i770. The display, ease of reading in low viz and at night, the extra options all seem pretty sweet to me. I do like better the shearwater of the two. I am wondering if it’s really worth the money to upgrade to this level of dive computer for a recreationnal diver? I’m hesitant to buy anything right now thinking that maybe something new will come out with 2020 .. any advice would be great!
