Humm. Ice 45 ?s

[SFC]

Was out fishing today, marking fish from 12 feet to the bottom which was 24' it was lit up. All the sudden the digital display showed 12' no fish, turned it off auto to the next 2 depth settings nothing changed. Shut the unit off, checked to make sure ducer was below ice, cleaned ducer. Turned on it is working again, now at times the big digital display shows varying depths like 14' 16' most times it seemed to coincide with the depth of my lure the smaller depthreading around the outside stayed consitent the rest of the day. Checked the connections, switched beams, which helped for awhile,battery showed 90%. Why would the big digital display be jumping from 12 to 20 feet at different times & at times be working fine. No one else on the lake also checked all connections.

If there is enough stuff in the water, the finder can get fooled as to what is bottom.

It was marking alot of fish, I was kinda thinking the same thing. First year flasher owner, I couldnt beleave the number of fish that were stacked up. If not for the flasher and a spring bobber I probably would of caught no fish.

I had a similar thing happen to my ice 45. My LCD display read correctly but the flasher part would bounce around to shallower depths than the correct bottom depth. I messed with the transducer connection and swithed it on/off which helped. I emailed humminbird about my problem and they told me to send it in for them to fix. So I'm waiting to get it back now.

Thanks for the reply and info, I plan on using it the rest of the season and see what happens, glad it is still under warranty. Anyone else have this issue?

If you have the Gain set too high it is possible to fool a flasher to mark a suspended target as bottom. That could be a lure, weed, or fish.

The flasher could mark this lure as constant bottom or it will do it intermittently when you lift of drop a lure it changes the profile of the lure and bounces back a stronger return signal.

In a nutshell, Less is More when adjusting gain. If you can mark your lure as the weakest color in this case green you can rest assured that anything that enters your cone angle will not go by unnoticed whether that be baitfish or fish. Gain set this way will mark anything entering or leaving the outside ( weakest part of the signal) of the cone angle as green.

As a fish moves in closer the signal will then turn yellow and eventually red(strongest return color) when its dead on your lure.

So as you can see your flasher is telling you more then if there are fish below you, its telling when they enter that cone angle, when they are right below and hot on your lure and when they leave. That can tell the mood of that fish and when they begin to leave its time to call them back.

I understand how to read a flasher and use the gain. My problem was happening with no fish on the screen and in 21 fow it would bounce up to 12-14 on the flasher but the LCD would still read 21 ft. It was the first time using my ice 45. I really liked the adjustable zoom and the large display. Still have my fl-8 as a back up unit that I've been using while the bird is getting fixed.

Were you on a severe slope? Sometimes that can make life hard on the unit.

Pretty much confirmed today I dont have a problem. Did the same thing today but only when marking alot of fish and had to have the gain turned up to mark a very small lure. Had the camera down today, fish everywhere plus lots of little bugs that they were feeding on. When the fish thinned out the large display stayed on the correct depth. Thanks for the replies.
