I have dove both Suunto & Oceanic air integrated computers (Vyper Air & VT4). The VT4 was by far more reliable. With the Vyper Air, I had to continuously reset the link. The Oceanic was much less so. Any air integrated computer an lose it’s signal. Our shop stopped handling Suunto because of the unreliability & problems getting Suunto to honor their warranties. The VT4 is no longer manufactured. It has been replaced by the Hollis TX1 (Oceanic & Hollis are owned by the same parent company). The Oceanic VTX has it (pricey) & the OLED screen is hard to read on a bright day. Any computer you get will have its ups & downs.
