      Members Only Fluid Forum View   08/08/2017

      Fluid forum view allows members only to get right to the meat of this community; the topics. You can toggle between your preferred forum view just below to the left on the main forum entrance. You will see three icons. Try them out and see what you prefer.   Fluid view allows you, if you are a signed up member, to see the newest topic posts in either all forums (select none or all) or in just your favorite forums (select the ones you want to see when you come to Fishing Minnesota). It keeps and in real time with respect to Topic posts and lets YOU SELECT YOUR FAVORITE FORUMS. It can make things fun and easy. This is especially true for less experienced visitors raised on social media. If you, as a members want more specific topics, you can even select a single forum to view. Let us take a look at fluid view in action. We will then break it down and explain how it works in more detail.   The video shows the topic list and the forum filter box. As you can see, it is easy to change the topic list by changing the selected forums. This view replaces the traditional list of categories and forums.   Of course, members only can change the view to better suit your way of browsing.   You will notice a “grid” option. We have moved the grid forum theme setting into the main forum settings. This makes it an option for members only to choose. This screenshot also shows the removal of the forum breadcrumb in fluid view mode. Fluid view remembers your last forum selection so you don’t lose your place when you go back to the listing. The benefit of this feature is easy to see. It removes a potential barrier of entry for members only. It puts the spotlight on topics themselves, and not the hierarchical forum structure. You as a member will enjoy viewing many forums at once and switching between them without leaving the page. We hope that fluid view, the new functionality is an asset that you enjoy .

interfernece rejection on flashers

Recommended Posts

My buddy and I were out sat. nite fishing in the same porty. He has a marcum lx3 and I have a VX1. no matter how many times i pushed my IR button I could not get the screen to stop dancin. Whereas his was workin fine once he found the right IR setting. Last year we used the same two flashers and they both worked fine next to each other. Does anyone have any thoughts on why they dont work next to each other now? It was very frustrating. Thanks for the input.

The ability to reject interference is based on different varying factors.

How close the transducers are together

Where the transducers are placed in relation to the water line/ice

Depth of water

Bottom Content

Gain Setting

Other flasher in close proximity

More times than not, it just takes fiddling around with them to get the right combination.

There are times however when all conditions come together that you just can't make it work. Usually this happens with deeper water and hard bottom

Does the VX-1 work fine when you have it on and no other flasher is on next to you? It should work with the gain down to 0-2 usually. I had an LX-3tc, Had to turn up the gain quite a bit to see my lure, and as a result I could not knock out the interferance from a nearby FL-8. Ended up having to send in to Marcum to fix. Not sure if the gain/interference problem was caused by the same malfunction or not. They ended up replacing the ducer and doing something to the head unit.

May want to give there service a call if you can't figure it out.

Like Dtro said, check start playing with how far down the hole you have the ducer.

The biggest factor I have seen is water depth combined with bottom content. The harder the bottom and the deeper you are fishing, the more issues you will have.

How deep were you fishing and how big of a jig were you using?

Thanks for the input. Yeah i had the gain up to about 4. I was in 33 ft with a small thin jig. That could very well have been the problem. when we used them together last year we were in 14 fow with spoons. only had the gain a little above zero then. Oh well. I still caught all the fish. he got skunked.

Check his gain. He might have it cranked way up and that will be overpowering your unit. With his unit down to a low setting you will have a better chance at getting rid of the interference. I had the same issue fishing with my cuz and his FL-18. I sold the VX-1 and got a LX3 for the extra power. The extra power helps me knock out his units interference. Basically, whoever's got the loudest radio gets to hear their music.

I don't believe that's true, broman. I believe flashers output the max power and the sensitivity (gain adjustment) is adjusting what the receiver displays.

Dave is correct.

I would have to disagree.

Here is an explanation of gain from the a wiki entry I found.

Quote:

In electronics, gain is a measure of the ability of a circuit (often an amplifier) to increase the power or amplitude of a signal. It is usually defined as the mean ratio of the signal output of a system to the signal input of the same system. It may also be defined as the decimal logarithm of the same ratio.

Below is what I found in the Vexilar manual which also backs up my explanation.

Quote:

GAIN

Gain controls the amount of amplification applied to the return sonar signal. Think of gain

as your volume control. You turn up the gain to see more of what’s below. You turn down

the gain to see less of what you don’t want to see. The goal is to fi nd a gain level that

shows you as much real information as possible, without displaying stray signals of clutter

and interference.

If you really wanted to know for sure you could put a multimeter in between the battery connection and see how the amperage draw changes when you change the gain.

I just tested the amp draw and it didn't change. So... I'm probably wrong. My electronics knowledge has been lost throughout the years. Why call it gain if it doesn't adjust you power. Can someone chime in?

Your quote:

GAIN

Gain controls the amount of amplification applied to the RETURN sonar signal.

The key words here are "return sonar signal". All common fishing sonars send their max rated pulse wattage to the transducer, and every time that transducer clicks it's sending a sound wave off into the water. When the sound signal hits something and is returned, the unit will then process that signal and display it according to your sensitivity or "gain" settings.

The gain you are refering to in electroincs does not have the same meaning in ultrsonics. When working with ultrasonic technology the lower the better. The higher the gain the more "noise"/false echos are returned. On most transducers, the output/wavelength is always running at the same frequency, while the gain control is reading the returns. By turning up your gain you are looking at that noise that you otherwise want to tune out. Hope that helps.

    • I just run to my dealer and buy the Suzuki stuff. It's a little more pricey but I don't sweat the extra $5-$10 per year. It cost me $50 for 4L of oil and the filter. I did the lower unit in the fall so I don't remember the gear oil cost.   Mine is a 2009 DF90, so pretty similar. Make sure that when you grease all of the zerks to look in your manual. There is one that you won't see until you tilt your motor all the way up. There is also one below the shift linkage that you can't reach unless you take off the lower skirts on both sides. There's about 10-12 screws holding the skirt on both sides.   Also, be VERY careful when putting the skirt back on. I just did mine again last night and accidentally pinched an air hose near the bottom of the skirts. It cut the hose in half when I put the last screw in place!
    • picking up the house tonight from a welding shop in town, guy said they get new houses that axles seize up on, sounded like they heated it up, broke it free, sand it down, grease it, add groves and it should be set. kind of scared to see how much they're going to charge me...    
    • I am new to the 4 stroke world and need to change the fluids in my 05 Suzuki 115 four stroke. What does everyone use for oil, filter, and lube? I was planning on using Mobil 1 or Amsoil 10-40 for the engine oil and the Lucas 90w gear oil for the lower unit. I don't know what filter to get. I know Fram has a filter that fits the motor. I run synthetic oil in my vehicles along with the filters designed for synthetic. I change my own oil and figure the peace of mind is worth the extra few bucks. Any opinions? 
    • Gobbler down...
    • Even with all the snow gone, they still dont want to come out in the fields. Even this morning i really got on the slate, this one come in at 640. Now im cayching brown trout. Good luck fellas
    • The mats aren't the worst option and would make sense for those days when the kids are you playing in the pool/sprinkler.  I'd still need to find a solution that prevents me from killing myself when taking the dog out in the winter.    I think my plan for now is to try one of the grip additives and test it out in an out of the way spot to see how it works.  If that looks promising I'll go that route and see how it goes. If that doesn't work then I'll look at other options. 
    • Well it looks like a successful morning, buddy got his bird. Weieghed in at 25.6#'s  10" beard and spurs 1 1/8". Heres the happy hunter.
    • Archery ia certainly a different bird! I too would probably have had a nice tom as well if I had a shotgun tag.   The biggest draw back for me is It make me much less Mobile.  A new test of my patience.
