Lowrance Hook Reveal Troubleshooting and
Hook2 or Hook Reveal - How to solve "not powering on."
If your Hook2 or Hook Reveal unit will not power on, please try these possible solutions:
1.
Check the connection in the back of the unit. Make sure that the power
plug is completely pushed into the unit.
2.
Be sure your boat battery is charged up and providing 12 volts through the
power cable.
3.
Check the fuse on the power positive line. Make sure that the fuse is
intact, free of corrosion, and the connections are solid.
4.
If you've used spade connectors, please make sure that they are properly
crimped and not loose.
5.
If your unit displays the Hook logo and immediately powers down, press
the power button repeatedly to cycle through the backlight levels. This will
brighten the screen and enable the unit to be used.
If you're having problems getting the connector pushed all the way in you can use
silicon spray to help lessen the friction caused by the rubber seals.
We recommend using silicon spray from CRC, Liquid Wrench, or WD-40
Spray a small amount directly into the connector hole in the back case of the product
rather than on the connector itself.
Using any kind of grease can create an airlock which pushes back on the connector and
may create an intermittent contact leading to loss of power or Sonar function.

To determine the source of the noise, shut off all electronic devices on the boat. Power up only the Lowrance unit. If no lines appear on the screen, then start powering up other devices one at a time until the lines reappear. You may need to route the cables of the problem source away from those of the Lowrance unit. - Page 4 In the search box, type the model of your Lowrance product plus the words "Unit, Manual, and Accessories."

- Page 5 mirror. The same principle applies to sound waves transmitted by your depth transducer and reflected off the seabed. If the depth works okay at lower speeds but not at higher speeds, this could be due to the angle of the hull changing relative to the seabed, which affects the transducer angle pointing at the seabed.
- Page 6 • Losing depth when another sonar unit is on: If two or more sonar units using the same transducer frequency are operating at the same time, one or more of them may lose the depth reading due to the interference. It is like two radio stations trying to both broadcast on 97.3 FM.

If your unit works on the other boat, your transducer may need to be replaced. Selecting your transducer The sonar image on your display starts with the transducer, so its characteristics greatly affect the performance of the system.

The HDI transducer comes in two frequency configurations, 83/200/455/800kHz and 50/200/455/800kHz. In both instances the 455/800kHz frequencies are what produce...
