My nephew, Cory Mullens, is presumed to have drowned in Saratoga 
Lake in upstate New York on November 24, 1996.  All recovery 
efforts have been futile.  I have been writing to newsgroups to 
obtain information on sophisticated recovery equipment. 
I have heard from the US Geological Survey and the writer 
recommends contacting the consulting firm in Newport, RI which 
assisted in the TWA crash site investigation.  He thought the 
name of the company is SAIC.
Also, do you have any information on "water cadaver dogs?"  
Please help if you can.  Thank you.  Judi Mullens

Whatever do you mean -- poor support.  Plus 3 has pretty good support
as far as I am concerned.  I've delt with support from a pile of
software firms and at least Plus 3 doesn't insult my intelligence, and
is honest about bugs.  That's more than I can say about other
developers.
Re: your locks -- what modules do they have?   I'm likly interested in
striking up a deal.

I am a party chief with 15 years experience looking to prepare for the 
LSIT exam.I would appreciate any helpful comments from PROFESSIONAL 
SURVEYORS .Does anyone have any comments on the PS &SIT; review courses 
by Prof.David Wahlstrom? Thanks,Bruce Joiner

Geotronics makes a very powerful software for posy processing.  You 
can get a demo disk from them.  It takes data from several brands of 
receivers.

I am looking for SDR datalogers (second hand).
If any one has any they are looking to sell we would like to hear from
you.

Another possibility is the standard grid/surface distance problem.
Have you applied the same scale factor to both surveys?

Does anyone know of a good CAD program for land survey work?
My father has tried several but most seem either unsuited to survet\y work or 
rely on a dongle to run (to prevent copying) as he wants to work at home as 
well as in the office (as is forgetful) transporting the dongle back and forth 
is tedious.
Anyone point me anywhere? Shareware preferred but not essential
Thanks

The usual procedure is to assume a bearing using a normal hand compass and
then apply a 'swing' correction once you've surveyed to two points with a
known bearing between them. If you wanted to reference to true north (or
south) you would have to perform a sun shot or star shot. I'll not go into
that here. As for attachments...???. I'm not familiar with that model.

I'm guessing not much (or whatever you can get for it).

Again try a survey supply store or survey equipment retailer , they usually
have a rental pool you can buy from. I'm not sure of the status of
Dietzgen.
