The Garmin GT15M-IH is an in-hull, single-band CHIRP transducer with a 600W power rating that operates in the medium band (85-165 kHz). It ships with four plastic tanks so that the user can choose the correct one for hull deadrise angles between 0° and 25°.
This transducer is for solid fiberglass hulls only. Cored hulls will degrade the signal. The GT15M-IH does not have a temperature sensor.
