Lay the pecan halves flat on a lined baking sheet in sets of four to form bases.
Melt the caramels in a microwave-safe bowl with water until smooth, checking at 30-second intervals.
Spoon the melted caramel over the pecan bases evenly.
Melt the chocolate chips in the microwave, then spoon over the caramel layer on each base.
Freeze the tray for at least 30 minutes to set the candies.
