I found with my Deleon if I put the environmental cover on the machine ran much better. Guess it kept the warmth inside and the cold out. :icon_scratch:

Planet1mars,

Hey, how's that Cibola working out for you. Thanks again for buying from me.
I do a lot of cold weather hunting but I really have not noticed any changes in the way the Tesoros work in the cold. The audio sounds slightly different but that's due to the cold effecting the diaphragm in the speaker. Let me know exactly what you are experiencing, I'm interested. Joe

I'm telling you my machine was crazy, it was unstable would beep even when nothing was there the display would get really slow. Once I put an environmental cover on it all those problems went away. I'm wondering if it has anything to do with condensation? If you take the machine from a warm place and use it in a cold environment wouldn't condensation form on the inside??

Hmmm

Hummm!

Strange, this thing about cold weather effecting the detector. I wonder what Tesoro would have to say about this? Joe

Yes the weather cover/dust cover.

Tesoro's exact answer to me was that they have encountered problems with the LCD screens being very slow when exposed to temperatures below 32 degrees. When I asked I was hunting in 20-30 degree temps. They are the ones that suggested putting the dust/weather cover on the machine and it made all the difference to my machine.

I will say that battery life sucks when it is that cold out.

It isn't just the Tesoro's that can experience some troubles in the cold weather. Batteries for one thing aren't putting out the power they will in warm weather. The cold shrinks contacts and condensation can form also from taking a detector from a warm place to the cold. Ice fishermen use these warm packets on the batteries and electronics to keep the flashers and cameras working while out on the ice, an these were designed for cold weather operation, detectors aren't. Anything you can do to keep the detector warmer than the outside air is good.

With the dust cover on, Tape a small hand warmer pack on the back of the cover. This way it won't be against the box and keep it warmer from the cold.
This might help you out. I tried this on my detectors and it seemed to help.

you could wrap it in saran wrap several times or try a plastic bag but I found the dust cover worked best.

It doesnt get very cold here in Louisiana. Yesterday morning it was an unusual 33° and I also noticed a little problem with my Deleon. It was more erratic, but it could have been the mineralization, the soil in this particular place. I know that there are some electronic components that perform differently in different temperature conditions. The effect on the batteries also sounds like something that could have an effect. I am anxious to try the dust cover as well.
