Lloyd,

Is this the project you were working on a year or so ago and were
looking for ni-cads for it? If so, did you go with ni-cads or
ni-mh's?

I made my own (at about 1/2 the price!) by mounting a Pirahna sounder in a
tupperware box. The transducer mounts on the transom with a bolt and butterfly
nut, or on a stick for Vinyl Valerie or other boat that doesn't have a
"permanent" mounting position. I threw my old Garmin GPS II+ in there as well,
and it's all powered by 8 AA rechargable batteries connected to some solar
panels on the top of the box.

Yup - I ended up with NiCads from a specialty battery store. Turned out I could
have used the NiMH's: the solar cells had lots of voltage.

I didn't remember seeing a follow-up so I was wondering about that
project. Are you getting good life with your usage? i.e. will the
combo of solar panels and batteries keep these electronics going a
decent amount of time? Or do you need to let the solar panel charge
the batteries a while before you can turn the electronics on. I
realize we're not talking serious battery usage on those electronics,
but am curious how well this all worked out for you.
