power rating on LX3

14 posts in this topic

I was at Cabelas in Mitchell this past weekend and the salesman told me that the Marcum LX3 power was tied to the gain. He said that if the gain was at 10 it would at that point be kicking out the full 1500 watts of power. And with the gain at 1 it could be down to 150 watts of power. I told him I had never heard or read anything like that before, and he said that the Marcum Rep. told him that. He then called another salesman over and he confirmed what he said. He said that it was like the "S" cable on the "18". Have any of you heard of this? Thanks

Yes most all sounders have a variable gain setting. Except the Vex which runs at 400 watts constantly. Thats why you need a supression cable in shallow water with the vex. The gain controll on the Vex dosent controll wattage(signal) sent but rather signal recieved.

I am of the understanding that 1) most units use high power output and insensitive receivers whereas Vexilar uses low power output and very sensitive receivers, 2) that all units put out their max power all the time and 3) the gain or sensitivity adjustment changes the sensitivity of the receiver, not the power output. One LCG that you can adjust the power output is the Zercom LPG2000 now the Hummingbird Legend. The S-cable on the Vexilar is called a suppression cable so it must reduce the power output.

No........

Vex puts out 400 watts constantly and the gain is controlled by what the receiver allows in.
Most other sounders wattage is control by the gain dial. If you have a 1500 watt peak sounder your not sending at 1500 all the time. You would have to have your gain maxed out along with your depht.
So if your where in shallow water and your gain and depht was turned down you would actually be using 150-200 watts Thats half as much as the Vex's constant 400 watts. Now tell me which receiver is insensitive. Which sounder would be more likely top spook fish? Lets say you put a 40 or 60 degree transducer on a Vex in 100-200 ft of water which is common on the Great Lakes. Its not going to work worth a bean. Why? Not enough Watts.

Hookmaster When you say all units do you mean all Vex's? If so then you would be correct. If you mean all brands then as I answered earlier its No.

Lowrance told me they do too.. na na nana na

Derek why dont we debate this on the end of a dock with a case of beer, rods and a couple dozen leeches on a nice summer night. grin.gif

Anyway my point was Vex is a constant 400 watts. And the gain/sensitivity are controlled with the receiver.

As opposed to most other sounders where the watts are not a constant and wattage is controlled by the user.

You mean if you maxed out the gain could you break up gull stones? grin.gif

No really dont try it, last time I did blood ran out my ear. grin.gif

Ok sorry. I dont know if you could hear the difference or not. I know if you hold the transducer up to your skull its louder.

I was talking all brands. The Genetron, being so expensive, isn't even on the list of ones I consider.

If you can adjust the power output up and down by the gain/sensitivity, wouldn't the "ticking" sound you hear from the transducer get louder/softer, respectively?

Not really on the topic, but just an FYI. A store located in Fridley has the LX3 on sale for $349.00... so anybody whos interested may want to check them out.

(I'm not naming the store, out of respect for Rick and this site, but you can email me if interested)

ST,

No harm done. If we can't have a little fun with ourselves and each other, we're in bad shape.

    •   It's hard not to lump them (Koch Bros) in with the Tea party as they spent millions supporting it and effectively, with some others, namely big tobacco, created the Tea party.      http://www.huffingtonpost.com/brendan-demelle/study-confirms-tea-party-_b_2663125.html  
    • I got an electronic sliding deadbolt on the garage and the house. It is the BEST THING EVER!!!! just push in 4 number and it opens up without any other input. To lock, you just push one button. I think maybe Quickset brand or something like that. I liekd it more than Schlage model.   My Mom had one that you put in the 4 digit combo and then have to turn a knob. Still nice, but the auto one is awesome.   It beeps for unsuccessful, and it willgive a red (rather than green) light and also a beepbeepbeep when the batteries get low. Pretty easy and forgiving to let you know when to change them. I have not had them go totally out on me yet in about 5 years or more, but I change them usually after about a week of beepbeepbeeping  I would guess I change them 1-2 times a year, more in the garage as it gets locked and unlocked more.   Seriously, best thing ever. I never carry keys anymore, never. I leave keys right in the vehicles in the garage, dont' bother bringing them into the house anymore. At the cabin I leave keys right in vehicles as well.
    • You do know Uncle Bengahzi........that burns are covered by the ACA.
    •   The best system is one where consumers are left with a choice, so yes. I would agree.

    • Nothing is going to be perfect but right now we pay way more for healthcare than anyone else, whatever we are doing is only lining the pockets of the industry and worse yet we are forced to pay. Let me know where it says in the constitution we have the right to be forced into paying high healthcare premiums, it doesn't exactly sound like America the free.

      Maybe someday I will research healthcare and write a report for you but I don't have the time right now. As I see it cutting out the middle man is good for 320+ millions Americans vs a tiny fraction of health insurance industry. We need to stop catering to tiny fractions of people for monetary gain and look at the big picture.
    • Will do.  We were just up there for ice fishing on Bass. First the drizzle and rain came, then the wind blew us all the way home.  We did get in some good sight fishing for bass though. 3-5 fow on the edge of reeds.  Real cool to see the bass come in and take your lure that shallow.  We got a couple of 18" +.

    • Del is that you shooting down any kind of change again? It can happen as soon as we decide we need to start doing what is in the best interests of the voters instead of what is right for some small segment of the economy. The politicians fear losing their jobs more than they fear these special interest groups. Even the far right has to see that letting the insurance industry have it's way and even worse force people to sign up for this stuff is a total crock. Ya ya we could go to a free market and let the market decide but I don't even know if we have free markets when it comes to big $$$ industries. They get what they want and we are forced to pay, not exactly a free market. Now if we could find a way to get there that would be great but there is way to much influence to let that happen.
    •   I think the countries in Europe that have systems that work still have insurance companies.   Why don't you research how it works in Germany and Switzerland, and get back to us with a report.    The problem with single payer is that, as we see with medicaid, that the government is tempted to reimburse at too low a level to sustain the providers.   Even the Brits seem to have a private system with insurance that runs in parallel with the government providers.    As for government providers in this country, the VA is an example.
