Regulators in White's

[Esteban]

Not sure for XLT, but Spectrum don't. Spectrum has thin printed fuse (trace). Diode option would be good. However... XLT most probably don't have it also. It was not supposed to be possible to reverse battery poles at original battery, that's why it don't need diode at all.
But....it is possible to reverse poles and kill it with alien battery...

Batteries housing is special here, this use 8 X 1.5 V batteries. In some case housing must be changed by standard when special fails or oxidation corroded the batteries housing... some people don't retired batteries and leave inside for very long time... this drift liquid and corroded the batteries housing.

people, why in 21st century whites uses step-down voltage regulator? LM2574-5.0. xlt is pretty heavy with 8*AA batts! it is absurd situation that absoliute best electronic device seems as MONSTER for any hands!

we must change IC on step-up one!

??? XLT was designed in the early 90's, so it's a 20th century design.

78S40 in White's 5900 and 6000 Di Pro is starting to work from 4 V. according to datasheet it works even from 2,5 Volts. what problem was to use Step-Down against Step-Up voltage chip in 90's Carl? I take ACE-250 in a hand... it is like a fuzz vs XLT... nothing in a hand I feel of!

Depends on the current consumption of the detector, and how long you want it to last on a battery. Theoretically, you can design any detector to run on a single AA battery, but if it runs only 15 minutes then that's no good.

Most detectors try to get 8 hours on a battery pack, and for the XLT that may mean 8-AA's and a step-down regulator. Had it been designed for 4-AA's and a step-up then it would have run for less than half the time.

Comparison "Spectrum" and "XLT"?

Hey, people! Please expression so that even we mortals can understand what you mean.
I tried to read in the Whites' site, what is the difference between model "Spectrum" and model "XLT". It appears that there is no difference. Just "Spectrum" and "XLT"are two words that form the name of the model "Spectrum XLT". Explain to me, please, which two detectors you compare in this thread?
