Anyone should be able to look at the numbers and be able to tell if it's rising and falling. Disabling it will result in some disabled or missing features. Therefore, at higher elevations, there will generally be lower barometric pressure than at sea level.A greater influence of fluctuations in barometric pressure, (the short term fluctuations that can influence fish behavior) are caused from local weather patterns which involve pressure ridges of air moving across the landscape.Barometric pressure can be measured in several different units of measure.

The needles are too fat and clumsy to set properly Over Top , Between or On the much smaller size of the increments seen on the gage which also cannot be eyed or seen very easily at all to begin with. However all of the other barometric pressure No tapping or anything. Higher elevation will have a lower baseline barometric pressure than lower elevations. Nearly all fish have a swim bladder organ, which is an inflated air sac that helps the fish to maintain neutral buoyancy in the water. Nonmercury, aneroid barometers work through a small, sealed metal chamber with most of the air inside drawn out. Please try againSorry, we failed to record your vote.

You can make your own weather predictions by following changes in barometic pressure.Identify your type of barometer.

I set the barometer to the local news and measured it against my glass barometer, they were not only identical but are rising and falling in sync. I read the instructions and it said to move the needle to the local setting of barometric pressure, with the screw on the back.....I did this and it felt very stiff to adjust it but managed to put it at my local setting. Tap the barometer lightly before taking a reading.Compare readings to weather reports and other reports of barometric pressure to confirm the accuracy of your unit.The normal, average sea-level pressure is about 29.92 inches, which means the barometer's needle will rest near 30.

It was $16. As one other reviewer has said, this is a novelty item and is very poor quality. This can mean sportfish that are hungry in preparation to hunker down, or simply sportfish that are taking advantage of the frantic small fish which are affected more by the pressure change.Once the pressure drops low in the middle of the storm, you can best assume that the fishing may not be stellar. Will update review once they deal wil replacing or refunding the product, should have paid attention to other reviews About the time I figured out it was hopelessly damage and I was going to request a new one that worked, they said my time had run out for refund or exchange (it has been slightly over a month that I bought this). Save yourself the grief and get a phone app. Llega descalibrado, y las instrucciones dicen que lentamente des vuelta al tornillo que trae por la parte de atrás, pero no tiene tope, y si te pasas lo hechas a perder, mi sobrino le dio vuelta muy bruscamente y lo echó a perder, ahora ya solo sirve como pisapapeles de 330 pesos, no lo compren a menos de que tengan todo el cuidado del mundo al calibrarlo After reading the reviews, I was under the impression I would be getting some light plastic Chinese piece of junk. There was a problem adding this item to Cart. So what I did was get a precision flat-head screwdriver, and turn the calibration screw until it became snugged.

Poor instructions.
