Has not sold yet. I am not sure about any warranty on it. It’s really new but I just am not familiar with policy about resale. I believe it comes with 3 year warranty but I might be wrong. You can check the mares website about that. As I stated though it’s only been on 1 dive and a couple of familiarization dives in the pool. Dove to about 90 feet at Morrison Springs FL and it’s been in the box since.
