2400 is correctQuote:

This was confirmed through Engineering.
Inquisitive minds might be interested to know....Quote:

I was under the impression that the 596hd di , 597hd di were 2011 items and came out this year in production. If thats true why were the boxes printed as 2400 watts peak to peak and then advertised by the hummingbird store as 2400 watts peak to peak. I would like to get this straight before I lay down 5 or 6 hundred on one of these units.Quote:

It will also allow you to track the lake/river bottom in higher noise conditions such as when running at high boat speeds. The disadvantage would be that the unit draws more power.
J ROW,
The 596c HD DI and 597c HD DI units are 2011 products. The problems with getting the specs right on the Humminbird web site, boxes and all are all due to some (late in the development cycle) changes made to the whole DI unit product line and a later manufacturing change that included only some of the products. The boxes had already went through proofing and were at the printer so were not changed in time. The Humminbird web site was corrected on most specs but it seems we still missed one or two. Unfortunately we cannot correct the web sites of other companies who sell these products.
All of the new DI units have the same 4,000 watt peak-to-peak transmitter.
J ROW''''''''''''''''''''''' i dont blame you this is a lot of money that we are infesting in ,for the majority of us,including me just recreational fishing. im confused now what the ptp power is on my 597 hd/di unit now. i can tell you this, are far as to the performance of my unit, im am more than pleased to say the leased about it.it out performs my 997 in every way that i can think of. the 50 channel gps locks onto satellites way quicker,it boots way faster, the scroll and pages are way faster,even my navionics card responses better .the screen is much brighter.you wouldn't believe how much easier it is to see .the only thing that it lacks is side scan. if you have any questions about the 597 hd/di feel free to ask me.ive got more than my moneys worth with it.its a great unit.in my option anyways.Quote:

So if you take 2400 watts peak to peak, divide by 2 = 1200 times 0.707, you get 848.4 watts RMS which is good for over 1000 feet. When is the last time you caught a fish 1000 feet deep?
This ain't the way they calculate the rms Bill. Trust me. It is BS the way they come up with the high power ratings of these transducer units. It is math magic, and cannot be measured in any conventional means, only calculated.Quote:
