FREQUENTLY ASKED QUESTIONS

Where Should The Gain Control Be Set?

Generally, the gain should be set to give you a good reading of the bot-

tom. This would mean a red leading edge. A basic rule to use is one num-

ber of gain for every 10 feet of depth. Although you will want to fine-

tune this setting with the current conditions in mind.

For ice fishing, you want set your gain level by the appearance of your

bait. With your bait down at the fishing depth, adjust the gain to make

your bait appear as a green signal.

What Color Should Fish Be?

For ice fishing with the FL-18, the fish target entering the outside of the

cone of sound will appear in green, as it moves towards the bait it will

add some orange into the center of the signal, and if the fish continues

to the perpendicular line under the transducer, red will be added to the

center of the fish target. These color changes will take place automati-

cally, without adjusting the gain control. This color change feature allows

you to observe the fish moving towards or away from your bait.

The fish can appear the same way on open water as they do ice fish-

ing, as the same rules apply. Although, instead of the stable platform of

ice you have wave and boat motion to contend with. If you see a red tar-

get separated from the bottom you can be fairly certain that it's a fish. If

all you see is green or orange you won't know if it's a fish until it turns

red.

How Long Will My Battery Last On The FL-18?

Run Time - The FL-18 draws about 275 mA, or about a quarter of an

amp of current The unit will run good until the battery voltage drops to

about 10 volts. Below this point you will notice lower sensitivity, as well

as, a much dimmer display. The Vexilar Model V120, a 7.2 amp/hr bat-

tery, will run the FL-18 for about 16 hours straight.
