Question 1

How do I use this?

Accepted Answer

This is a Barometric Pressure Gauge. It does not use any power source. It shows the barometric pressure as a direct reading on the scale. The barometric pressure can influence the attitude of bass which usually dictates if they will bite aggressively or if the bite will be very slow. This gauge must be calibrated before use. There is a small adjusting screw on the rear to calibrate the gauge. It is best to get a local barometric pressure reading from a known accurate source to initially set the gauge.

Question 2

How do u calibrate the trac outdoor t3002 fishing barometer?

Accepted Answer

Current Barometric pressure can be found at www.weather.gov by typing in your town and state, or by checking your local weather news. Use a small screw driver to turn the adjustment screw on the back of the barometer to make the Red Hand match your current pressure. Once adjusted, it does not need to be re-adjusted unless it is taken to a higher or lower altitude. 
The hand on the lens can be adjusted to match the current pressure. The lens hand is used to track changes. After the pressure changes you will see the pressure rise or fall compared to the lens hand. 
Barometric pressure trends can happen quickly (10 to 30 minutes) when a front comes through. Other times when weather is steady the pressure can stay the same for many days. 
If you have any further questions please contact TRAC directly at (615) 462-6224 from 9 to 4 Central time Monday to Friday.

Question 3

How long does it take after calibrating for it to start properly working and the hand to start moving?

Accepted Answer

The 'hand' moves immediately if there is pressure change.
To calibrate, log on to the Internet and find your local pressure, and use the screw in back to align the hand with the local pressure.
The movement of the screw is very small to align to the local pressure.  There is no reason to turn it so much that it falls out.  I turned mine maybe an 8th of a turn.
Mine has been very accurate to the local pressure.  Satisfied with it.

Question 4

Will it withstand a rainy day on a boat?

Accepted Answer

Likely it would.  Though the clear plastic cover and case are not as robust as one might like, the outer rubber guard is durable.  It wouldn't take much to crack the cover so care would need to be taken.
