Question: Is there a warranty on this item?
Document: Used on 4 dives soon after purchase. My first dive computer. Worked great for my needs.Initial dives were on an afternoon, followed by additional dives the following morning. Computer treated this as one long day, so morning dives were started with computer still in surface interval mode, counting as dives 3 and 4. A little confusing, but makes sense as it was less than 24 hours from previous dives.
Answer: no
