1.       What’s the depth capability of Mini Fishing Rado?

Ans: have a perfect performance with the depth 0.9~45m. However because of the nature of sonar, the sensor will not work properly. So, we strongly suggest you use the unit in water area above 0.9 meters.

2.       Nothing Happens When I turn the Power On?

Ans: 1) Make sure that you have installed a good set of batteries and aligned them as per the diagram within the battery compartment.
2) Make sure that the temperature of the environment is above -10℃ (14℉). When using this product in the cold environment, please make sure that the temperature of the main unit is above certain degree.

3.  When I use Mini Fishing Rado  in some water area. The depth reading varies continually.

Ans: That maybe caused by overly choppy water. When used in overly choppy water, the sensor together the float can’t be kept at a stable position, which cause the sensor continually incline to every direction. On such condition, please set the “sensitivity” to “low”, that maybe helps. Otherwise, we suggest you choose a calm water area to fish.

4. How do I understand the depth detecting range? What’s the relationship between actual depthreading and depth detecting range number?

Ans:  The unit will automatically adjust the depth range according to water conditions. It always keeps the bottom displayed in the lower portion of the screen. When the depth unit is set to feet, this fish finder has the following depth ranges: 10, 15, 20, 30, 60, 120, 200 and 400 feet. When the depth unit is set to meter, the fish finder has the following depth ranges: 3, 5, 6, 10, 20, 40, 60 and 120m.
 

5. I can see fish under the sensor, but nothing appears on the display?

Ans: As with the depth reading, the Fishfider will not detect any objects that are closer than 0.9 meters from the sonar sensor. If you’re fishing in water that is less than 0.9 meters deep, it is recommended not to use his product.

6. What depth do you suggest for the shallow alarm number?

Ans: It depends on your fishing habit. Generally speaking, the shallow number should not be less then 0.9. maybe you would not like to fish in a correspondingly low water, let’s say 2m, or even lower. Then you could set the alarm number a value. If the actual depth is less then the value you set, then the unit will alarm.   

7. Can my Mini Fishing Rado can be used in saltwater?

Ans: Sure,it was developed with special sonar technique. It can distinguish the difference between fresh and salt water. By pressing MENU, you could choose “water environment”, then set it to “fresh” or “salt” according to the actual water environment.

8. Can I expect Mini Fishing Rado  to distinguish big / small fish?

Ans: We are developed with the capability of distinguish big / small fish group, instead of single fish. In a certain time if the fish appears frequently, then the fish group will be regarded as “big”, otherwise will be regarded as “small”. 

9. Is there any limitation with the speed of boat When use Fishing Rado for boat fishing?

Ans: We suggest the speed of your boat not being less than 8 km per hour. The speed of more than

8 km per hour may result in intermittent signal and unstable depth reading.

10. Weak Bottom Echo, Unstable Depth Reading, or No Fish Signals?

Ans: 1) Make certain the sonar sensor is pointing straight down.
2) Extremely heavy vegetation may confuse the sonar signal, causing it to misinterpret the depth. If you are certain that the readings are incorrect under these conditions, discontinue use.

3) Oil, dirt and fuel might cause a film to form on the transducer and reduce its effectiveness. Cleaning the face of the sensor might help.

4) Electrical noise from the boat's motor, trolling motor, or an accessory interferes with the sonar unit. Rerouting the transducer cables away from other electrical wiring on the boat may help.

5) Please check the battery voltage. The unit's transmitter power will decrease due to the voltage drop. And this will reduce its ability to find the bottom or targets.

6) Please check the Sensitivity settings. Choosing High Sensitivity might help.

7) The sonar might be in turbulent water. Mounting it in a smooth flow of water might help.

8) The reason might be that the boat speeds over 5 mph (8 kph). Slowing the boat down might help.
