Dimensions

In the Dimensions tab you can customize Proteus with the exact dimensions of your vessel

·      Note: Press the (+) or (-) button to move in 6-inch increments or hold own to move through the numbers at a faster pace.

           

GPS and Compass

Compass Bias is when the compass heading does not match the GPS heading.  You can enter a bias (offset) to adjust it. 

·       Manually adjust your Compass Bias by pressing the (+) and (-) buttons or….

·       Calculate Compass Bias calculates the compass bias by comparing your course-over-ground to your compass heading while you are moving

o   In an area with no current, move at 5 to 10 mph (8 to 16 kph) on a smooth path (turning is OK, but avoid sharp turns).

o   press the rotating arrows (1) to start calculating bias. Hints about your speed and the calculator progress will be shown. This can take a few minutes.

o   Once it is complete, the calculated bias will be shown in the field. Press the up arrow (2) to populate the results in the Compass Bias where it becomes the new applied bias. 

On the same tab switch from GPS and Compass to Radar for Radar Settings

            

In the Radar tab enter in all your vessel Radar position data and select the verify you have selected the correct Radar that is on your boat. 

Radar Bias is like the Compass Bias, but in this case the radar hits are offset from the on-screen charts. 

·      Manually adjust your Radar Bias by pressing the (+) and (-) buttons or….

·      Calculate Radar Bias 

·      Note:  This process is usually NOT recommended. Please use Compass Bias to adjust major offsets and make only small manual adjustments to RADAR bias if fine-tuning is needed.

o   In an area with no tide or current, move at 5 to 10 mph (8 to 16 kph) on a smooth path (turning is OK, but avoid sharp turns). You must be within RADAR scanning range of three or more channel markers which will serve as reference points to automatically align the RADAR. The center of a bay, with RADAR adjusted to barely reach the shoreline, is usually a good location.

o   press the rotating arrows (1) to start calculating Radar bias. Hints about the calculator progress will be shown. This can take a few minutes.

o   Once it is complete, the calculated bias will be shown in the field. Press the up arrow (2 to populate the results in the Radar Bias where it becomes the new applied bias. 

Draft and Transducer Depth

In the Draft / Transducer Depth Tab enter in all your vessel draft and transducer depth data.  Proteus will display depth tiles as reported from the last official sounding (or the last time you traversed the area), but the system will always monitor the transducer and report if the seafloor is getting shallow based on the changes in depths being reported by the transducer.  The Proteus system will always provide 2 forms of depth reporting; historical and changes being reported by the transducer – these alerts are adjusted for local tides.

If your Draft Depth and Transducer depth are the same, then press the copy button. 

·      Note: If you do not set your transducer depth, you will not have ability to do depth remapping. 

Calculate Transducer Depth compares your depth readings to the map data to estimate your transducer offset.  You must be moving more than 5 mph and in a mapped area for this to be accurate. 

·      Note: We always recommend the offset published by your boat manufacturer.  If possible, use manufacturer data vice this calculator. The more accurate the depth data the better protected you are from running aground.
