| My HB shows a double return I'm in water under 14 or 15 feet. The digital reads at twice the actual dept any suggestions on how to correct?

Location: Otsego, MN | I have had this issue in the past in shallow, hard bottom areas. The signal is too strong and what you are actually reading is the signal bouncing off the bottom a second time and returning. If you adjust your sensitivity down significantly it will fix that. |

| Yes, sensitivity is to high for that bottom composition. Also with unit off you can unplug and replay the ducer wire, on my trolling motor us2 I did all three connections and the one inside the tm head was the culprit. |

Location: NE Ohio | set your sensitivity at about 13 and manually change your bottom depth to something a little deeper than you are. take it off of "AUTO" bottom depth and that will solve your problem. |
