Title: Vex FL-20 and DD-100 odd display
Post by: B540glenn on Feb 20, 2019, 07:43 PM
I picked up a Vex FL-20 with a DD-100 this season.  The DD-100 unit displays a different depth than the main display.  (see pic)  Is this normal?  Is this something I can calibrate?  Is it defective?  Am I reading it wrong?
At one point I was over 4 feet of water and the DD-100 display showed 49.8 feet. 
This pic show 17 feet of water while the DD-100 displays 50.

Got any suggestions?

My flx28 digital depth on the dial goes wonky sometimes in low power mode which it looks like yours is in.try it without lp mode once.

where you truely over 50 feet of water or not if so then you need to turn the unit off and hold the gain knob down when you turn the unit on. doing this will put the unit in deep water mode where X1 = 30 ft and X2 would = 60ft. if you didn't hold down the gain button when you turned the unit on you will only be in the 20 feet depth when on X2.

I wouldn't think he would be in 50ft and using lp mode.

When I was in the 4 feet of water and the DD-100 showed 49, I could see the bottom.

I'll try it with normal power this weekend.
Thanks for the tip.

Yep.  Had the same issue with my FL18 and DD100 - until I found that video.  Works great on HIGH power only.

That's something that should be in the user manual. 
It could be as simple as a line that reads, "The DD-100 only works in normal power mode."   ::)

didn't catch that the first time I looked at the picture. then I didn't know that Vexilar and Tom put out that video. just goes to show we all are still learning new stuff and never know it all. Good to know if the question ever comes up again in the future.

I'll have to check the paper manual again.  The electronic version I have states,

DD-100

...The digital depth display will always give you a depth reading as long as your Vexilar FL flasher is turned on and the transducer is in the water. The digital depth portion of the indicator will work even if you’re not in the correct depth range. This will allow you to get your flasher in the best depth range possible. If your display is blinking or the depth numbers are going up or down rapidly, it could be that you’re over a huge school of fish or baitfish OR the bottom is irregular. ...

I guess the whole moral of this story is,

Don't use the DD-XXX units on Low Power.
