How many hours per 9V?

Just wondering what the typical life of a 9V is in a detector. I was hunting yesterday and the Outlaw was acting strange. I replaced the battery this morning but it's raining so no hunting today. According to my notes the old battery had 21 hunts on it. I usually get to hunt from one to three hours per hunt. I'd say that battery had a minimum of 30 hours on it.
 
I get about 10 or so but i do not use headphones
 
My experience = Duracells go 20-24 hours with both the Outlaw and Silver using headphones.
 
This Outlaw user went 72 hours with the OEM Panasonic Industrials:

I have gotten 40+ hours on my COMPADRE. I use headphones. I pin point very fast. I don't wast time playing around going this way and that way. I get it done and dig... KEN
 
I use headphones. Sounds like it was definitely time to replace. I wish the Outlaw had the same style battery check as the Eldorado.
 
I got about 15 to 20 with the Vaquero with head phones, when I used batteries. I use Powerex 9.6V (230mAh) NiMH rechargeable batteries now. I have had good luck with them.
 
To little, with low battery detector loose depth. Very bad design, use always good battery or connect different, bigger one. Tejon is much better solution compare to 9V design.

Well, I'm going to say they shouldn't.
Whatever battery system or voltage is used the detector only runs of the top of the battery, or batteries.
So, if its setup to run off 12 volts of batteries, then it actually isn't operating at 12v but probably 8 volts. So, you only have a useable voltage range of 4 volts and anything below 8 volts is DEAD! (regulators in the circuits cuts the power flowing to the unit at 8v)
If it runs on a 9 Volt battery then its operating at probably at 5 volts with the regulator cutting anything above 5 volts.
Now, the problem is with some detectors is the low battery warning system, if any and how well it does.
I'm a firm believer in all detector should have something!
I have one that just has a simple red LED that when the battery gets low it lights,
One has a battery level meter,
One, has an alarm that sounds like a phone ringing.

But no ONE of these has any performance loss above the low battery warning.

Mark in reality Tesoro performance drops very quickly with 9v battery, but usually users do not notice this.

Well, I'll still say they "Shouldn't" and that doesn't mean that the Tesoro's don't work like a flash light in that every time you turn them on they are not as bright as the last time. (a standard flashlight)

But, electronic devices and their components SHOULD be set to run correctly at a base voltage which can and should be well below the supply voltage. Its sad to think that to keep peak performance you have to change batteries every six minutes, or to say that my detector,
@ 9 volts goes 8" deep, then
@ 8 volts it drops off to 6" then,
@ 5 volts it drops to 4"

Again, I'm going to say they shouldn't, (or to say they don't have to)

I know my other detectors DON'T.


Heck, now they even have flashlights with regulators in them that don't go deem until they reach a base voltage. (there costly, but they are a electronic flashlight)

I do think that Tesoro could do a little better at a Low Battery warning or alert system.
