IMHO an external transducer is a mistake on a skiff. Unless you aren't really ever fishing it as a skiff. How many times are you fishing a flat and see drag marks from your trim tabs? Now picture your transducer grinding through the mud and oysters. Shoot thru hull gives you all you need for a skiff and you don't have to worry about getting it busted. Is it as accurate for depth and temp as an external? No its not but its plenty accurate enough.
