[PSUBS-MAILIST] Comms for the SeaQuestor Subctive

[Alan via Personal_Submersibles]

Had another look at the Ocean Reef M100.
It has the ptt button on the unit rather than off the headset wires.
https://www.amazon.com/dp/B001BMJE4E/?coliid=IGXIWPFWXXW7O&colid=1BFRZ0AJ9GCCA&psc=0
$675- is very good for the transmitter headset & transducer.
 The headset looks reasonably cheap but easy to upgrade.
What I can't find anywhere is a Watt rating for any of the Ocean Reef
units. 
When I'm comparing Ocean Reef with OTS, all other things being
equal, the Watts is what will give me the longer range.

>> Hi Alan, my plan is to use the ssb2010 with headset in the sub and the St101 on the surface with headset. Once I get all the pieces I plan on running some experiments on the volume and headset control. I have access to 6 mics, and 6 transducers at a pretty decent price. So i may grow my inventory to play  with . My 101 showed up today, and i should have the 2010 and headsets later this week.

>> Jon, thanks for that info. I am now leaning heavily toward 2 x SB 2010.
