thanks you chaps,
i had'nt considered earphones - might give them a go first, even though my patrols are long. i like the idea of the sound coming around from behind.
i was struggling the other night to listen to the hydro's and thought its about time to upgrade - i'm leaning up n over the keyboard my with ear to the speaker. this makes me laugh when i think about someone finding me in this position.
are you alright - are you stuck, do you need help ?
QUIET - QUIET, THEY'RE PINGING US !!
cheers
