What does the Calibrate button do? Why does the Minn Kota cord keep wrapping? Why won't the MSB stay in place?

NOTE: The MSB Team has been working on code to prevent wrapping entirely.  We are actively working on adding another sensor to the hull that will solve the problem.  Until that sensor is available, using the tricks below will help.  Our plan is to have the sensor ready by June 2020.  The new sensor will be available in the online store.

If you have trouble with the MSB getting over wrapped while sitting on station, go to the section below titled CALIBRATION.  If you have trouble with it getting over wrapped while navigating to waypoints, there are a couple things you can do to help in the TECHNIQUE section below.

TECHNIQUE:

1) When needing to navigate a bot downwind, let it drift in to position by hitting the Stop button instead of using the Navigate button.  This is a problem because the hull whips around multiple times in fast succession, which is the most common cause of over wrapping

2) Do not use the Anchor button while a bot is active moving.  The bot will immediately over shoot its target and the head will spin 180 degress to get back to where it needs to be.  Instead, hit Stop, wait 5 seconds, and then press Anchor.

CALIBRATION (ProNav Gen 1):

There is a Calibrate button on the Remote screen that does a compass swing of the electronic compass in the navigation system.

This normally won't need to be done because it was done before the device left the factory. If you find that the Bot won't hold position well or won't anchor at all, a calibration needs to be run.

Make sure the ProNav depth collar is set correctly (measured between the bottom of the motor head and the top of the spin preventer). For inflatable decks, that is 4.5" (12m). For aluminum frames, that is 5.5" (14cm)

The process takes 30 seconds and shouldn't be interrupted.

Before running, you need to remove the spin preventer block so that the motor can spin a full 360 degrees.

The hull should be held in place while the calibration is run. The head of the Minn Kota will spin a full 360 and then will spin back a 1/4 turn. After that happens, wait 15 seconds and then you will be all set.

CALIBRATION (ProNav Gen 2):

The ProNav Gen 2 compass is self calibrating.  You only need to calibrate it if support tells you to.  Here is how to do the calibration
