The equipment is housed in a heated GRP cabinet within the lifeboat station with the full tide pressure point being mounted on steelwork attached to a concrete leg of the slipway and the mid-tide pressure point mounted on steelwork directly below the lifeboat station. All three pressure lines are monitored by the POL data logger.

The tide gauge is levelled to the tide gauge bench mark suppored by Ordnance Survey auxilary marks.
