SURVEYING A LAKE

The most successful anglers on any body of water are those who fish it

day after day and year after year. Eventually, they learn the hot spots

that produce fish consistently. They discover through experience

where, and at what depth, they can expect to find the fish they want at

any season. And they realize that these productive areas change

throughout the year depending on water level, temperature, food, and

other factors.

With the Magna III, anyone can eliminate guesswork and concentrate on

the areas where fish are likely to be. Even if it’s the first time on the lake!

The most efficient way to become acquainted with a body of water is to

survey it with your Magna III Start with a map of the lake, if possible, and

indicate the promising spots in relation to landmarks on shore. Keep a

few marker buoys in the boat, ready to toss overboard. When the

Magna III indicates a school of fish, throw the buoy out. With the school

thus marked, you can make your turn and come back to fish in exactly

the right spot. This is essential when you’re far from shore on a big lake.

Unless you mark the school of fish when you’re over it, you may not be

able to find it again.

FISH ARCHES

Fish arches are created when the cone of sound passes over a fish.

The distance to a fish when the cone first strikes it is shown as "A" on the

next page. When the center of the cone strikes the fish, the distance is

shorter as shown "B". As the cone leaves the fish, the distance in-

creases again as shown in "C".

When the Fish I.D. mode is off, the depth of the water will affect the size

and shape of the fish arch due to the cone angle diameter. For example,

if the cone passes over a fish in shallow water, the signal displayed on

the Magna III may not arch at all. This is due to the narrow cone

diameter and the resolution limitations of the display.

Very small fish probably will not arch at all. Medium sized fish will show

a partial arch, or a shape similar to an arch if they’re in deep water.

Large fish will arch, but turn the sensitivity up in deeper water to see the

arch. Because of water conditions, such as heavy surface clutter,

thermoclines, etc., the sensitivity sometimes cannot be increased

enough to get fish arches.
