Fish Hawk TD
Fish Hawk Electronics
The patented Slip-Ducer design attaches easily and requires no permanent installation. Because it rides on the downrigger cable or probe tow line, the Slip-Ducer stays perfectly aligned with the Fish Hawk Probe for maximum signal reception. 10-foot cable.
US Patent No.: US 10,345,280 B2
I emailed FH and Trevor told me I could use my X4D just like the normal X2 option. I figured I might as well use the tool for more than just salmon fishing. All you need is the slip ducer and way to deploy the probe and weight. I recommend the FH rod and 2lb weight. Ive used the set up for walleye trolling and it works great. It will help you dial in a pattern for the day if you are dealing with underwater currents.
