Sonar & Down Imaging on my FF - Kayak Fishing Adventures on Big Water’s Edge

IN2DEEP · 05-12-2014, 03:16 PM

I just wanted to share how I'm making use of the "down image" feature on my Humminbird graph

I was at Lake Isabella last week and had a chance to do a fair amount of open water trolling.
At this time, the water level is way down and there are a lot of trees being exposed that you don't see at higher water levels.
However there are still many "shorter" trees that are still underwater waiting to snag up your trolling lures

I had some encounters and did lose some gear

I got to an area that had some very good looking readings in the "sonar mode" when I switched to split screen sonar/DI I realized that it was a submerged tree.
The rock off center to the right is holding fish.
I took a picture of the screen because it was such an eye opener.

The DI mode is coming in handy when there is too much clutter to identify whether there are fish or bait present or not
Kelp stringers and turbulent water (near rocks) are a few of the places the DI is shinning for me
So, my conclusion is that the down-imaging feature is useful in some situations

Down imaging is awesome. Side scan sonar is awesome too if you have a trained eye. Some things that can cause image anomalies are wakes, sea surface (surface returns), or crosstalk (electrical or acoustical signals). It's a great tool for fishing no doubt.

My FF has downscan. It's perfect for telling the
difference between bait and kelp. The kelp looks
like a tree, with a main trunk and its branches.
This is the tool to use when fishing the kelp line.

That is a pretty cool image.

Now if I could only find a combo unit that includes DSI,GPS, and a WSB Whistle

Yeah Damn cool image, laying on the couch last night drinking a beer, I looked over at the girl and said I need a new FF look how cool this is. LOL

If you find one with a WSB whistle post it up if you find one with a YT whistle PM where you found it.

I picked up a new Lowrance Elite 4 HDI. Man that thing is amazing. Last weekend I went fishing with a buddy who did not have one. I caught 3 calicos that I spotted using the fish finder. He did not catch any bass.

I just load up on beans and beer the night before and hang my ass in the water. Underwater beer farts make for the perfect croaking sound.
