defining the bottom with FL-8



I know you are suppose to be able to tell what type of bottom your fishing in based on the thickness of the red line and the trailing echo on the FL-8, but I sure can't tell very well. Does the size of the trailing echo define how soft the bottom is? Any suggestions?

Your battery power will affect this also, along with how deep a water you are fishing. But yes, extra bottom echos often mean hard bottom, the lack of an extra bottom echo can mean a soft bottom. Try leaving your gain at one setting and getting to know what it is reading.. An underwater camera like an aqua-vu will also help in learning what your vex is telling you... Once you have used the two togeather for a while you can gets somewhat accurate in guessing bottom composition by looking at your vex!

My FL8 shows a very slight green line as bottom in sandy areas--I noticed this this year while using my camera at the same time.

I also realized how much of a "Dead Zone" there is on the FL8 between my Jig/Bait and true bottom--on the FL8 it looks like 6". My bait disappears off the flasher and looks like it should be laying on the bottom of the lake, but it's actually hovering in the "dead zone" just off the bottom--hence the reason for the FL18.

This "dead zone" is where a majority of our prey sits in the winter (perch,'eyes)as they come into the cone-zone to look at our offerings.

In watching the "dead zone" I've learned to notice when I have a fish hugging the bottom because the bottom indicator line on the FL8 begins to flutter slightly. Now when I see the flutter and the fish are neutral, I'll drop my offering right on the bottom and they will just pick it up if they want it.

      We've been big fans of the 3" minnows, and 5" leeches, along with crawlers, great color combinations, with floating versions ta boot.👍👍     Found the pinched half crawlers to work great for adding spin to "slow death" presentation...

      Okay, I’m not into gore. I’ve only had to do surgery on one hook and that’s enough. PSU, I’m wondering how you’re doing. Cliff offered good advice. In the Frazer Bay Area, bobbers are my only means of catching fish of size. I t seems like the dinks are dominating the reefs. Spinners can pick up fish near structure. I was looking back at my logs recently and late July has always been tough.  Dick

      I haven't done it on all my stuff, but I don't avoid using a bait because I mashed the barbs.   It would probably be a good idea to mash more of them, even if just to make it easier to get them out when they get hooked on something like clothing or a rag.

      Manitoba requires the same, and I agree, we didn’t notice a difference either except for keeping bait on the hook.  It’s just a hard mental block to get around. @LBerquist, ouch!  Unfortunately I know what those are like.  Both getting them out of myself and helping others!  You can pinch the barbs down on any hook though.  Some lay down nice and others will break off, leaving just a little bit of a rough bump which I kind of like better.  There’s a little bit of grip left that way.

      Thanks for the tip something new to try 🙂

      I wish barb less hooks were more available. I'd switch, heard they come out easier....

      The gulp crawlers in packages are tougher than those in the alive container.  The one in the picture is from the alive container.  Both versions work well on spinner and slow death rigs.
