Hey mtnredhed.....great info...thanks... you help clear up allot of the curiosity on the gear. Its neat that you got to use the sea voice. I wonder ... if someday... my state of the art gear will be looked at in the same antiquish way. If your ever in this area.. I’d like to share a dive with you..but hey no oceans here only quarries.:) maybe I should change my name to "quarryfloor".
