Congratulations!
You now own a Sonar Super Snooper. The FR-300 beams down at the speed of sound, to scout
out fish where they are... where you can't see them. Like an underwater partner, it gives
you a fish's-eye view of the scene. The 300 is fun to use and easy to take care of. It's
waterproof and it even floats. Read on and find out how easy it is to use.
QUICK START
After installing the batteries (see instructions) place the transducer end into the water
and pull the trigger. Your LCD (Liquid Crystal Display) readout will start supplying you
with information.
  |
Either of these will flash when trigger is pulled to indicate model and
proper operation. F3 is the FR-300 and E3 is the IE-300 |
 |
Normal reading is between 2 feet and 99 feet. |
 |
A number from 1 to 3 alternating with another number indicates a reading
over one hundred feet. The example to the side indicates a depth of 245 feet. |
 |
Two dashes indicate either overange or no signal returned. |
BATTERY INSTALLATION
Your new 300 is ready to take fishing. All you have to do is load it with one nine-volt alkaline battery.
The battery fits in the handle, in a waterproof cartridge. Remove battery
cartridge from handle by holding unit upside down and simultaneously pull trigger and
apply pressure to the bottom of the battery case. See (7) on illustration. If very tight,
use a thin blade screwdriver inserted between case and trigger assembly using extreme care
to not damage surfaces. The case will crack if forced. Install battery as shown in figure
below.
Do not bang or slam the cartridge back into place, a firm push is enough.
Caution: The unit is not waterproof when the battery cartridge
is out of the handle. Do not expose to water or dampness when the battery cartridge is
out. Change the battery in a protected place where their is no danger of splashing or
exposure to weather.

FINDING FISH - SCANNING
Fish move pretty fast, but you don't have to be fast to find them with your sonar. In fact you'll have better luck by scanning through the water slowly.
If you scan slowly you'll know when a fish swims by or when you scan over a fish because the digital readout numbers will suddenly change. For example, if you have a reading of 45 feet, and the display changes to 15 feet, this shows that a fish or some object has come into the path of your sonar beam.
You can point the unit straight down for scanning or off at an angle toward the bank or shore. If you point at an angle it may over range (two dashes alternating with a 99 or the last good reading) until a fish or some other obstacle comes into the beam.
As an example, you may show a reading of 45 feet. |
|
The display then changes to 15 feet which shows a fish or some object has come into the path of your sonar beam. |

ICE FISHING
The IE-300 Ice Eyes is designed to locate those elusive big ones right through clear ice.
There are two methods for using the IE-300.
Shooting through the ice to find the best place to drill your hole.
Scanning through the hole. Remember that the liquid crystal readout is a liquid so keep Ice Eyes warm under coat if numbers are sluggish.
Shoot Through the Ice
Under favorable conditions this unit will shoot through up to 3 feet of ice. Unfortunately
conditions aren't always favorable. Leaves and debris frequently are frozen in the ice as
well as layers of snow and slush which contains air. Air is the main enemy of a sonar
beam. When shooting through the ice make sure the coupling between the nose (transducer)
and the ice is as good as possible. Even tiny bubbles on the transducer can kill the sonar
beam. Some methods of coupling that often work are:
 | Fill a flat bottom bucket (i.e. ice cream bucket) with water. Place bucket on flat ice and place nose of Ice Eyes in the water and pull trigger. |
| Fill a (ziplock) baggy with some antifreeze. Place bag on ice and press the Ice Eyes on the bag and pull the trigger. |
| Scoop out a shallow hole in the ice. Fill hole with water then place nose into the water and pull trigger. |
You should get an instantaneous reading when the trigger is pulled. If not try wiping the transducer with a cloth to remove air bubbles.
Scanning Through a Hole
After you have used the Ice Eyes to find the best location for the hole, you may now use
the Ice Eyes to scan for fish. Again contact with the water is very important. Remove as
much slush from the hole and wipe the transducer to eliminate any air bubbles.
KNOW-HOW
Crazy readings are caused by...
| weak batteries air bubbles on nose end |
| air bubbles on nose end |
No reading or flashing reading...
| you are shooting over 399 feet or under 2 feet |
| your batteries are dead. |
Air bubbles can be...
| rubbed off after dipping in water |
| prevented by occasional spraying with acrylic like Krylon #1301. |
Fog in the window...
| is caused by changing batteries in a damp or humid place. |
| will dry out if you leave unit in a warm dry place with battery cartridge out. |
Accidental water in case...
| must be dried out |
| will take several days to evaporate. |
Water turbulence or motor wake...
| will cause crazy readings or no readings |
MAINTENANCE
You can keep your 300 in top shape by keeping it reasonably clean. For washing, use a mild detergent and a soft cloth. So long as the battery cartridge is in the handle, the 300 will be waterproof, and you can dunk it in water for cleaning.
