Targets are off by about 20 degrees, and we have tried everything on the config menu to try to correct this. What do we do to get targets to be on accurate bearing? Thank you .

You never say what maximum number of pumps, but half the number would do.

- Make sure you're in GTA5 story mode
- Go to start menu
- In Settings, go to Controls
- Switch targeting mode to Assisted Aim (Partial) or Assisted Aim (Full)

With Assisted Aim (Full) you can even switch between targets.

You can hear when the pellet hits the target - it is also obvious from a distance at where the bullet hit.

Jumping from side to side with your feet together targets the inner as well as outer thighs. It also works out your calves and glutes. Jumping on one leg will target the glutes, calves, and hamstrings as well as the core. Front to back jumping targets all of the lower body muscles.

This was a answer to a different unit but possibly would apply so i thought i'd pass it on talks about false echos.

best to you

You just tap the targets in the center. If you tap correctly, the target will automatically move to next position.

Try calibrating the unit by watching this video and performing the same action

Have you checked all of the resistors inthe convergence circuit as well? If not, check them for the correct impedance.. Remember, you have to pull one side of the resistor out of circuit to measure it correctly. 
If all of the resistors are good, then you have to do a coarse convergence adjustment on the set through the service menu.. if you need the service manual for the convergence directions, I have one uploaded in the technicians corner of techlore.com

If the AIS targets are out compared with radar target then turn compass to superimpose radar on to AIS.
If the AIS info is out compared with chart then suspect GPS. This could be yours or theirs depending on how many targets are out and whether it consistantly in one direction.
Good luck

Go to "applications"

Select "prefs"

Select "touchscreen"

Tap the targets on the screen as precisely as possible, then select "done"

NOTE: you need to tap at least 3 targets - maybe more if you don't tap carefully.
