Shooting-thru the hull of a boat/canoe or ice can be sometimes be difficult as hidden air pockets will prevent you from obtaining a reading. Make certain that the hull or ice is solid from the surface to the water with no air bubbles and/or gaps. Shooting thru composite hulls (plastic) or cloudy ice is not possible as there are tiny air bubbles present in these situations. ALWAYS use a small amount of water to attach the sensor to an ice surface.
