1) Upper connection tab - The probe unit transmits the RF signal onto this stainless steel tab. Attach the downrigger cable to this tab. This connection must be isolated from the water with rubberized electrical tape to prevent the transmitted signal from being absorbed in the water. Rubberized electrical tape is included with the Depth Raider system.

2) Raised Boss - This raised boss is part of the injection molded housing. It's purpose is to provide an electrically isolated flange that the rubberized tape can adhere to ensuring a good seal. This boss is also handy to quickly determine which side of the probe unit connects to the downrigger cable.

3) Lower Connection Tab - This tab is used to connect the downrigger cannonball. Be sure to use an 18”-24” drop leader of lower test. If the cannonball gets snagged on the bottom, its better to lose the cannonball rather than the probe and the cannonball. This tab is internally electrically isolated from the upper connection tab. Therefore, there is no need to use rubberized electrical tape on this interconnect.

4) Ferromagnetic Rotor - We call it a ‘Paddle Wheel’. This device is molded of plastic and magnetic particles. It has 6 teeth or ‘paddles’ around the circumference. Every time a tooth passes by the magnetic sensor located inside the unit, an electrical pulse is generated. The probe unit measures speed by counting these magnetic pulses over a specific period of time.

5) Battery Cap - Remove this screw-on cap to access the battery compartment. The cap features a two-O-ring seal to prevent water entry into the unit. Also, this cap has an aggressive knurled exterior that aids the user in removing the cap with wet, slippery hands. Be sure to keep the O-rings well lubricated with Vaseline or similar lubricants. Tightening the cap without lubricant can quickly damage O-rings.
