Default New Fish Finder

I'm running an older center console, 22 Foot Hydrasport Ocean Skiff. I do a great deal of fishing in Long Island Sound. My fish finder (Garmin 240) - low end unit that worked well is "almost dead". It acted up over the weekend and read bottom then lost bottom on Saturday. The transducer looks OK, etc. On Sunday it did not read at all unless I turned the gain up all the way- and then it just about picked up the bottom. This is the first time I had a problem with the unit. Since I have it in a slip, I'm not going to replace the unit until I pull the boat at the end of Nov. The side question is any ideas what is up with this unit?(from my perspective it is obviously the transducer.) It would be great if I could get a bit more out of this unit until the boat comes out.

The main question - is what fish finders do the "pros" recommend. I'm mainly using the unit to fish rips and bottom fish (I really just need to mark structure) - of course I like to see if the fish are there as well (especially on the troll) - but the point is that I need a simple reliable unit.

I presently have a Garmin GPS and a Garmin color chart plotter - both of these units work fine. I tend to not like "combination units" (the point being that if a combo unit "goes down" your in big trouble).

Thanks - Jack

I use a Garmin color fishfinder (2010c) and like. However I still think furuno is the bench mark when it comes to fish finders.

Through hull or transom mount on the xducer? Either way I would suspect buildup on the bottom, of the boat or the xducer. If you can get to the face, clean it off with some 600 grit wet/dry sandpaper and check again. That'll help isolate it out. Also does the head unit have a simulator mode? That can help isolate as well.

Just some thoughts.

Thanks for the responses. The unit is a transmom mount. I will try to get to it with the sand paper over the weekend. What is odd to me is that the unit (on Saturday) was working fine, lost bottom (totally) and then picked up bottom sporatically - on Sunday it did not work at all (until the gain was turned all the way up). The unit is not in simulator mode (after last weekend I'm an expert at programming it). Again, it is a low price unit and I got at least 5 years out of it - I just need to pick up reefs until Thanksgiving weekend when the season ends for my rig. What is the thought on Lowrance units? (I used to have a Lowarance combo GPS/Fishfinder - I think that unit lasted 5 years as well.) They seem to build nicer transducers. What about color versus black and white - I like color but I don't know if it is critical for inshore - all my fishing is from skinny water to a max of 150 feet. (Bass, fluke, scup, tautog and of course the inevitable blue fish that come along in Long Island Sound).

I think what Mr. T was saying is that if you put the unit into simulator mode and the head unit display shows a normal looking bottom, then you can eliminate the display/monitor as a potential culprit. Next focus on the ducer, the ducer cable/connections and finally, the head unit itself. In addition to the monitor/display, the head unit contains all the electronic wizardry needed to send, receive and process the signals coming and going from your transducer.

Don't know what your budget is willing to bear but Boater's World has the Lowrance LCX-111C on a blowout sale for $1299. That is a superb price for an awesome machine. I'd pick it over a comparable Furuno, Simrad, Koden or Raymarine unit anyday.
