Fish Hawk 840 to X4 Upgrade Kit
Fish Hawk 840 to X4 Upgrade Pack
Upgrade your old Fish Hawk 840 Thermo Troll to a new X4 System. Kit includes the X4 Display and X4 Probe. The Fish Hawk X4 offers double the performance and uses the same transducer and power cord as the 840 meaning you dont need to re-wire anything on the boat, the X4 plugs right in!
If you have an older 840, this is the least expensive way to buy the X4 Probe and LCD Display.
- Includes X4 LCD and Probe
- Plugs in to 840 transducer and powercord
