## What reviewers say

**Suunto Ocean** — Only one whitelisted tester, TechRadar, ran a genuine hands-on review of the exact Suunto Ocean; dive-specialist outlets like DIVE Magazine and Wareable fall outside the whitelist. TechRadar's Craig Hale dove with it repeatedly and calls it a vast improvement over the D5, praising the display and value while flagging the non-titanium case and USB-A charging. (1 sourced review.)

**Garmin Descent Mk3i** — Only one whitelisted hands-on tester (TechRadar) reviewed the exact Garmin Descent Mk3i, scoring it 5/5 overall. It praised battery life, comprehensive dive features and durability, but flagged the high four-figure price (plus paid T2 transmitter) and a relatively clunky UI. All three quotes were verified as literal substrings of the fetched article. (1 sourced review.)
