LCD Questions

Why would I need to calibrate my speed and temperature sensors?

When the sensors are manufactured there are variances in the value of the components used. There may also be changes in the design that require that the unit be re-calibrated. If the unit is new, or you are replacing a sensor, you should make sure the readings are close to accurate by comparing them to a known value (i.e. a thermometer for temp or a GPS, or speedometer, for speed). If the LCD is reporting a wrong value, correct it in the units menu calibration.Contact serviceif you have questions.

Can an LCD depth finder be used for ice fishing?

Generally, yes. You do have to sacrifice some speed, not to mention the color. Even if the LCD is operating in an "instantaneous" mode, the actual pixels cannot light, and turn off, as fast as a neon or LED display. As far as freezing, we, and most manufacturers have designed that problem away. At least for the average fishermen, anyway.

Is it true that Vexilar introduced the first LCD depth finder to the sport fishermen back in the ’80s?

 Is it true that Vexilar introduced the first LCD depth finder to the sport fishermen back in the ’80s?
Yes, it was the model 480. There are still a few in operation today. The models 481 and 482 followed with the additions of on-screen speed and temp as well as dual frequency transmitters.

What is a pixel and how many do I want?

A pixel is simply one dot on the LCD panel. There are thousands of them on one LCD panel. The smaller they are, the clearer the picture. The more you have in the vertical direction, the better depth resolution you have. The more you have in the horizontal direction, the more time your image stays on the screen.
