Re: [PSUBS-MAILIST] periscope

Thanks Jon,
Have been running around looking into this.
I was tempted with the thought of having several differant cameras mounted
around the sub. It's a great idea. I found a 10" netbook for $200-NZ but am 
wanting a screen
around 4" or less as I'm building very small, & the smaller you go with 
these netbooks the more you
have to pay. For others with bigger boats this would be a good option. Just 
take your laptop down
& plug in your cameras.
Alan
