What's the difference between the 688 and the 788?
It is now live on their website - http://www.humminbird.com/Freshwater/Product-Category/ICE/
This is a true statement, and the difference is a faster processor than the 597, and a better resolution screen
I swear I just read that the resolution was better on the 597ci than the 688. But I can't remember if it was the DI model or the ED. I have been reading about this unit and the elite 5 chirp and can't decide which one I want for this year.
Yankee Troller-How is the 688?
I've run it in 100' of water for Lake Trout, 10' of water for Gills, and 20-30' of water for Walleye. It performed flawlessly in all those situations. I've really only run it in sonar mode with the Real Time Sonar (RTS) screen on the right, which is basically a vertical flasher. I've also only run it in 200khz, which is the 20 degree cone (narrower of the two). I have nothing to compare it to other than Marcums LX9, which my buddy has. That has a couple extra little features, for example, telling you how wide your cone is at certain depths. It has hung evenly with this unit in all circumstances, and we fish together a lot. I wish the screen was a little larger, but lets be honest how big is too big for the ice.I just put the new Lakemaster chip in it for the Northeast. WOW! Those two together give you great detail on the mapping of lakes.
Some of this is a bit unrelated, but I had a few questions. Are you using the 688 on that yacht you drive around ontario, or a 2nd smaller boat? Was wondering how deep you are able to track downrigger balls? Also, have you used the navionics hotspots premium maps? And how it compares to lakemaster? Trying to decide between the 2 for use in a helix.
