Looks like a school of yellowtail underneath you And it looks like you're about to get bit.

If it's constant, change your settings. On a lake it's easy to get closer than you would on the ocean. You may not be "too close" respect wise, but you could be picking up interference from another boat's fish finder. If your beams cross, it would show diagonal lines like yours is displaying.

The pump could also cause the disturbance but only if it's super close to the transducer. Make sure nothing is aft of the transducer. I try to keep mine mounted as far back as I can. It could also be your paddle turbulence.

Thanks all. I will experiment some more. I have to admit that I don't know what I am looking at unless it is bottom structure. I like the look of the color unit posted. Will the spending ever stop?

Salty Pirate - I bought the unit about month ago and still playing with it. What setting do you normally have it when fishing La Jolla and/or Mission bay? The manual was saying something about fresh water setting if it is less than 1000 ft - I did buy the 50/200 ducer and really liking it...also can you tell the difference between the 80 vs 50 around the bay area?

I was wondering the same. I had read that the 50/200 is better, but looking at the specs, it sounds like the 83/200 is good out to 1,000ft, and the 50/200 is good out to 2,500 ft. So I was wondering if the image quality was somehow different between the two 'ducers at the depths we are usually kayaking (all less than 1,000ft). If the image quality is same, then I'm assuming you wouldn't see a diff between the 50 and the 83 until you get out to waters deeper than 1,000... right? Anyways, I'm excited to try my new fishfinder when I get back in town.

no issues with the 83khz. i can see my every section on my squid ganion at 120ft. crosing over the canyon the pic is very clear. 83/200 should be good to 1000ft.

yep I leave mine on the fw setting as per instruction. I just learned how to save screen shots. next time im at lj ill get some pics so you have somthing to compare.

Salty Pirate, Honcho,

I'm figuring out how to set up mine. I'll PM you guys so this isn't a total thread hijack!

BUT... I overheard somewhere that the HDI transducer is not going to be optimal mounting thru-hull (goop-mount).. I'm looking at either the RAM or the Mad Frog Gear Liberator Mini transducer mount arms.

Ok... thanks guys.
