Can someone turn theirs on (just on counter) and tell me where your green line starts. This one I just picked up used is at just ove one foot. Is this common or is something out of wack.

This is right from Vexilars HSOforum hope it helps.

How can I test to see if my transducer is bad?

Try this test: Hold the transducer about 24" above a hard floor. There must be a flat solid floor below, no carpet. Place a hard cover book on the carpet if you need to. If it's an Ice-Ducer style, hold it by the cable. If it's a Puck or High-Speed, butt the top side up against the underside of a table. This is to insure that the transducer will point straight at the floor. Now, turn the flasher on to the first range. With the Gain set to zero, you should see a mark at the 12:00 position indicating the top, or your transducer, and another mark at the 9 foot line indicating the bottom, or floor.

Notice how the depth is completely inaccurate. The reason is that the speed of the burst of sound coming out of your transducer is traveling much slower in the air than it would be in the water. So the unit thinks it's deeper. Also the strength of your system is much weaker in air than water. The top line should be mostly red in color. The bottom line may be green, orange, or red (depending on the strength of your system, how straight your transducer is, and the type of floor). If you cannot see the floor mark without having to turn your gain up, try a harder or smoother type of floor. If there is no change, the system has a sensitivity problem. You must see at least a green mark, on a hard floor, with the gain at minimum to pass the test.

You can judge the overall sensitivity of the system by doing this "air demo" test, but you can't tell if a weakness is due to the unit or transducer (which is much more common) without replacing one or the other with a known good component. Borrow a friend's transducer or bring your setup into your local Vexilar dealer and ask if you can use one they have in stock for your test.

If your system passes the test, but you are still experiencing trouble seeing your bait out on the ice, clean the transducer face with hot water and a common dish washing detergent. Also, be sure you wet the transducer by rubbing water into the face of it before you start to fish. This insures good acoustical contact with the water.

If your transducer doesn't pass the test, it will have to be replaced. Weak transducers cannot be repaired. The dealer should be happy to help you out. If the flasher itself proves to be the culprit, our service department should be able to solve your problem.
