Is there something wrong with my Vex?


homerj

Question

I have a two year old vex fl8. I've been fishing a little deeper that I have previously (26') and have noticed something unusual. When I first set up, I have the gain set at 0-1 and can see things nicely. After a while (~30 minutes)I'll lose all contact and have to increase my gain, sometimes up to 4 or 5. Then after a while, I can reduce it back near 1. Do you think this is the vex, or some factor in the water? I know it isn't a battery issue because I always fully charge it when I'm done using it - and the display is bright.

I had a similar issue with my Marcum LX 1 last year and it turned out to be a bad transducer. You might want to check that.

If it is your transducer, you could easily test that by swapping with a buddy and see if his works. Any fl8 or fl18 transducer will work. They are all compatible. Also, there is a good test you can do at your home to see if your transducer is functioning properly. It is explained well on the vex website (FAQ), but it goes something like this:

Let your transducer hang off a table at home (assuming you have an iceducer) about two feet above a solid floor. Don't do it over carpet, something like hardwood, tile, concrete. etc. Turn your vex on the first range and put the gain at zero. You should get at least a green reading at about nine feet. Sound doesn't travel as fast in air as in water so that's why it will read about nine feet. This test still won't ensure that it is the transducer, but will determine if there is a sensitivity problem. The transducer would be the most likely cause of this problem, but it could be the unit.

As mentioned above, it could be your transducer. Whats puzzling is it worked fine then didn't work and then worked again. Makes you wonder if there was any current or your ducer may have been tilted from leaning on the side of your hole.

This is the first time I've used it this year on the s2 range. I've always fished at 20' or under prior to this using the s1 range. Hope this doesn't point to more of a possibility with the unit itself. I've had it less than two years and haven't abused it.

Check your transducer cable for cracks or small cuts, water will enter the cord and give you funky reading, the cuts or cracks can be fixed by coating the area with silicone, dry the area,ruff up the area and put on silicone or liquid rubber, this comes in a small can and cures in 12 hrs.

      Maybe the bamboozler will end up being like every fish story, some old timers holding their hands out as wide as possible to demonstrate to a youngster just how big it was....

      Fished a bigger lake, fish or at least the eaters are on the mid lake humps. Water Temps 68 degrees, freezer now has 6 total as I've been eating fish often. Tomorrow we chase the 30" walleye for catch and release.

      I just returned home today from 4 wonderful days of fishing my favorite lake. We arrived late Saturday and was able to fish a bit that evening. Our group was comprised of my cousin, one of our very close friends and myself. On Saturday evening we managed to catch 16 walleyes on crawlers, leeches, and minnows. In spite of less than perfect weather conditions(95 degree heat and high to near hurricane force winds) we ended up with 103 walleyes boated and perhaps that many missed and lost during retrieval through Wednesday early afternoon. Minnows worked best one day, leeches worked great one day, and crawlers were the ticket Wednesday with our biggest fish of the trip coming that day. The bites ranged from very light to jerk the rod out of your hand. Our terminal gear consisted of jig/minnow, Lindy rig, to my old standby 4 ft leader, 1oz bouncer, 2 red beads, and a Gamakatsu size 8 orange hook. The bouncer rig outfished the rest by a wide margin. Speed was a huge factor and .4-.6mph was the speed that worked best. The high winds made boat control/speed a real challenge. We caught all of our fish from 8ft to 24ft with the optimun depth ~14ft give or take. When we got to the lake the water temp was 64.5 degrees and yesterday afternnon when we quit, it was 68.5 degrees. We did not see any significant amounts of mayflies except in the water columns in a few areas of the lake. The fish we cleaned went from stuffed with mayflies, full of crawdads, to full of perch minnows. We found the fish in the rocks and on mud flats. I looked for the fish with sonar and only fished where I found fish. I found our fish in the east end of Big Bay, Daisy Bay, Armstrong Bay, Portage Bay, and Bystrom Bay. We caught fish at every place we stopped. Wind dictated where we fished on any given day. On Monday, I had to cross the east end of Fraser Bay and in over 60 years, I have never seen it that rough.  We found the cheapest gas at Shamrock Marina($6.29/gal) and the best bait at the Y store. We have eaten pizza at the Vermilion Club for more years than I can count and, to put it bluntly, we were very disappointed this year. To us, it was definitely not the same quality of pizza we have become accustomed to. Suffice it to say, we will be ordering something different from the menu in the future. All in all, Lake Vermilion provided us with another lasting memory. Great fishing on the greatest lake in Minnesota. We will return in mid-September and we are already anxious. Pictured below is my cousin with two nice walleyes caught 10 minutes apart. They were caught on crawlers.   Good Fishing MarkB🙂

      Maybe pay him in smoked pike so he can taste some fish instead just crunching down on walleyes all the time! 😉
