Bradley ? I mean , we got one and not our usual two , but still . <| sep |> These questions are great additions . Also , if the gym was profitable when they bought it ? Or are they trying to turn it around <| sep |> Hahaha that ' s great . I ' m always scared that the guy I ' m seeing won ' t like them . Current guy has mentioned how he hates facial piercings other than small nose studs and gauges , so I have been very hesitant about telling him . Guess the surprise tactic is my only option P <| sep |> This would vary project to project and sensor to sensor . For the transducer I left out in Newport recently , i had a 120 amp hour lithium battery that was about a meter in length and about as big around as a softball . Depending on depth and length of time left in the water , the equipment you use and so on , you might ping anywhere from 100 w to 1000 w for a single beam once a second for 20 minutes an hour as an example . On the other hand , other deployments had so many sensors they put in banks of 24 volt marine batteries that made up the bulk of the system . Some setups are actually tethered to land power sources .
