Nothing wrong with Radio comms on surface, in fact you should have a VHF for ocean water anyway. Depending upon the location of the transducer on the vessel, at the surface you may find you don't have enough water column to communicate effectively. Test first.<br clear="none">

Dad and I are planning to try a little experiment in regards to the mounting location of Snoopy's transducer array. The idea is to mount the array on a hinged whip behind the hatch. While she's on the surface the transducer will be under the waterline for surfaced communication with surface support (if the boat and sub are out of earshot of one another). When Snoopy submerges, the array's float lifts the mast erect over the sub, becoming the tallest part of the vessel while submerged.<br clear="none">

Just an idea, but we're keen to try it when we get the chance. One possible drawback is entanglement danger... we've been thinking a lot about that lately. ~ Doug S.<br clear="none">
