The Tetra 5050 system includes the L&M WAL, flat port adapter, 2 wet-mate bulkhead connectors on housing plus a spare, 3 sync cords (wet-mate to S&S), complete set of o-rings, spare ROC boards, spare mode control gear set & ONE 5050 camera. (Just sold one camera.) Everything cost me over $4000. Just the housing, WAL & adapter port list for about $2100 (which doesn't include bulkhead connectors). Everything is less than a year old & like new. $2500
