NO, bolt snap to 6ft leash that I held on to at times. So we were not tethered together. The vis was poor enough that at times you couldn't see your fins. Being as cold as it was it allows us to maintain a relative distance during the dive. Works well as a team. One person navigates. The other watches for depth and maintains the dive plan. Definitely beats losing sight of your dive buddy and having to call it a day due to poor conditions.
