I agree with Rik. 4ft is too shallow for a polaris.
The polaris really comes in to it's own where you encounter much deep water especially where it is close in or there is a steep drop off from a ledge into deep water that damages your line when quivertipping.
As for how, I like to use a patternostered groundbait feeder rig under them when fishing for bream. Much more sensitive than you would at first imagine.
