My calculations: Take the square root of your mother's hat size and divide it into the weight of your fish locator = the number of LI AA's to bring on a trip. puckster

Is the weight in ounces or grams?

MP: So how deep does that "Whalon puddle" actually get?

83Ft right where you said it would be.  But the wind made it hard to stay there.

A set of 9 Energizer Ultrimate Lithium will supply 250ma at > 11 volts for 12 hours. They can be purchased at Sams Club for about $17/set.

That reminds me Magic, I meant to ask, don't you use 9 AAs in your battery tube?

One reason I ask is I've never seen AA batteries come in anything but even numbers so 9 seems like a pain to me. The other reason is a fresh set of 8 in the finder reads 17v which concerned me the first time a borrowed a 12v finder.
1.5v x 8 = 12v.
9 would be 13.5v on the label but 19v in practice?

FWIW the only resistor I saw was the one resistor i saw. What 8" wire where? I know what a circuit is but beyond that I'll take your word for it. I know what a 6-32 is though! :)

9 batteries verses 8? I have always used 9 but in looking at data that I have recently taken if  you use 8 Lithium batteries when the voltage gets down to 10 V only 5% of the energy would be left in the batteries.  So it would be more economical to run 8.  The data shows that 10 Alkaline are required to get the energy out before the voltage drops below 10 volts.

I did not have a suitable resistor so I used about 8 inches of some Nickel-Titanium single strand wire I had for a different project.  That is some strange stuff makes a good resistor but hard to make good electrical connection to.

Does the name of the material “Nickel-Titanium single strand wire” or the statement “That is some strange stuff” ring a bell? I am sure you have read about it some where!
