Marcum/IR Question...



Here is a question for all of you Marcum users...

I was using my Marcum on Sunday in 55 feet of water, the zoom was off.

In order to seem my lure, I had to turn the gain up. However, when I turned the gain up enough to see my lure, there was all kinds of what appeared to be interference flickering in and out in the bottom 20 feet of the screen. If I would turn the gain way up , the bottom 20 feet on the screen would be completely lit up. This interference only appeared in the bottom 20 feet, I thought it might have been some insect hatch or plankton or something like that.

I was the only person within a 1/2 mile of this spot, there were no other electronics anywhere near my Marcum, however I pushed the IR button a few times and the interference completely disapeared, and I was able to see my lure clearly.

So why did the IR clear up whatever was on the screen???? Especially when it didn't seem likely that it was caused by any other electronics?

When I have fished in shallower water (35 feet or less) I have never experienced this.

Not complaining, I love the unit, I just don't understand how the IR cleared up what was on the screen...

Any ideas?

JWB475 The MarCum's IR isn't just for dealing with interference form other sounders as you found out. Nice isn't it.
How it works you'd have to ask one of MarCum's engineers. Probably changes the way the receiver looks at the echo's profile.
All I care about is the IR on the MarCum works and I have yet to have any problems getting rid of interference from any other sounders no matter how many are around me.

      Now many businessmen open their companies in the USA, as this makes it easy to apply for an American accelerator and communicate with any investor. The specialists of https://www.fintecharbor.com/company-registration-in-the-usa/ will help you register a company in America and you will be able to feel comfortable in your business.

      It is strange that the developers did not think of such a nuance. In any case, you need to place an ad on the labor exchange, where you will find employees for the company and they will work with you, only you will need to conduct a preliminary interview

      Creating an application for such a hotel would be the best option. Place your ad on the job exchange on the Internet, I know a few of these, then you can find developers for yourself and the work will go much easier

      You won’t have to search for a long time, rather you will need to choose from the options offered. Look on the Internet for all the available options, such developers usually have their own sites that have all the information you need

      I am sure that if you search in the google search engine you will find a company that is dedicated to that, but to be honest I have not much idea, I never planted the idea of something like that, from my ignorance it is very complicated, but maybe someone who have more notion of it can guide you and can even recommend a company with a good reputation that is dedicated exclusively to it, good luck with all that

      Haven't really targeted geese, think we've got 3 Ross geese a blue goose and one Canada goose. We focus more on ducks, especially when we can get them in the field. Greater and lesser Canada geese around but they are spread out tons of feeds but no large feeds

      Finally got the choirs done. Roofed a shed and built a woodshed. Most done by myself. Now's time to go fishing before the deer season.  Found some crappies tonight, caught 11, missed at least that many. West end. Skunked again, how'd you do, saw you heading out?

      The three on top of the pile are geese. Smurfy. 😉   +1 on the decent shooting!  Thanks for the pics.  This was one post that got me to log back in to spam central.   Going dark again….
