Is the MOB Pole Obsolete?

[shorebird]

I want to add a MOB pole to the vessel, but some have said the MOB feature on the chartplotter makes the pole obsolete. Now I know its a matter of personal choice, so I still want the pole, but I don't see them near as much as in the past. Will you rely on the MOB button in a MOB emergency, or do you have the pole, or both, or neither?
