True Dual-Channel 1kW CHIRP
CHIRP is the most sophisticated sonar technology available for use by the fishing and boating public. CHIRP is an acronym for Compressed High-Intensity Radiated Pulse. What it means to you is much better target resolution, clarity and crispness than any other sonar system. Having Garmin true dual 1 kW CHIRP as your traditional sonar allows you to adjust CHIRP frequencies to low/medium, low/high, medium/high to further optimize your sonar performance. Transducer sold separately.
Clearest Scanning Sonar Images on the Water
Adding CHIRP technology to DownV resolution, target separation and clarity of the sonar images of fish and structure that pass below and to the sides of your boat. Built-in to our new GPSMAP xsv combos and GSD 25 Premium Sonar Module, it uses 1 transducer for traditional CHIRP HD-ID sonar and CHIRP DownVü and SideVü scanning sonar. Transducer sold separately.

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.
—Brittany R., Arkansas -
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!
