Dual Algorithm
DOUBLE THE BENEFITS

Choose the Right Algorithm for Your Dive.
Pelagic Z+ offers a conservative approach to recreational diving or maximized bottom time for deep and decompression dives, maximizing dive times at depth without excessive penalties. Pelagic DSAT safely maximizes dive times for repetitive, multi-level recreational diving.

Dive in Sync with Any Buddy, Anywhere.
Dual Algorithm allows you to choose the algorithm and its conservatism. This means the Pro Plus 4 can closely match your dive buddy’s algorithm, eliminating the need for either of you to cut your dive short, even if you’re diving different computers.

  1. Grateful Diver

    Been diving with the ProPlus 3 for years, and was so excited when I heard the ProPlus 4.0 was coming out. Never used Bluetooth for much but man it’s handy syncing my dive functions and data with my cell phone.

  2. dakgreenmtnboy

    Just got the new 4.0 and love the blue tooth; makes things SO much quicker and easier. Fantastic so far!

  3. Dakgreenmtnboy

    Just got this and it is a breeze to setup and use. LOVE the bluetooth feature. Pretty much the same as the 3.0 with a bit larger readout.

  4. Dakgreenmtnboy

    Just got this a couple of weeks ago, it’s my new primary with the Geo 2.0 as a backup. LOVE the blue tooth functionality!

  5. GM

    Just ran the computer over multiple days and 9 dives. Matched it against my dive buddies computer from another vendor – the 22% bigger letters with multiple sub-widows was a joy and easy to use for older eyes. Really a great product.

  6. Scott McPhail

    This is my first dive computer and it is fantastic. Extremely easy to use and read in and out of the water. Bluetooth is great. I can transfer my dive info to my phone while still on the boat between and after dives.

  7. warrendreynolds

    Purchased this unit in May 2021. Used my damaged Proplus 2 with the trade in/up option. Easy to read at depth, great unit. Had one problem, very first time I attempted to disconnect the unit from the hose, when I reconnected it, I had a good air leak from the bottom of the computer. I confirmed the quick-connect attachment on the computer was tight and no debris was in the hose end, and the leak was still present unit about 1500 psi, then it would stop. I unscrewed the quick-connect base completely from the computer, reattached it and the leak stopped. Go figure, no more leaks.
