GT15M-IH Plastic, In-Hull, Mid-Band CHIRP Transducer - 85-165kHz, 600W, 8-Pin
GT15M-IH transducer is ideal for boats that want to install the transducer inside a fiberglass hull and not on the transom where cavitation could cause issues. It can be used with a hull deadrise angle between 0 and 25 degrees and is excellent for boats traveling at high speeds that want to maintain accurate depth readings.
The 8-pin transducer with 4 plastic tanks features mid-band CHIRP traditional sonar (85-165 kHz) and has a power rating of 600 W. It can be used in conjunction with a GT30-TM transducer and an adapter cable so you can maintain depth at high speeds and scanning capabilities at trolling speeds.
For installation, follow the included instructions carefully to avoid damaging your boat.

Testimonials

The 2" slab snack swims just like the real thing. I’ve been fishing crappie for 20+ years — these baits flat-out catch fish.
Jeremy M., Mississippi -
You can tell these aren’t mass-produced. The jig heads are balanced, sharp, and durable — love supporting a small business that gets it.

I’ve used big-name brands for years, but Kill Um’s baits consistently outperform them. Caught my personal best this spring using the Slab Twister!
