Thread: DI question

I have a fiberglass flat bottom, Florida folk know it as a Stumpknocker, and am interested in upgrading for from an Eagle Fish ID 128 - it’s ok, laugh- mounted on TM to a DI that will operate on plane. The bottom is fiberglass and plywood. Will a shoot through transducer work?

Lord knows I appreciate those who understand the electronic stuff, but it is beyond this humble typist. Is there is something that will show depth, some conture, and maybe a fish?

The Eagle still works like it did when new, but is slower than Congress.

Any suggestions?

Don't feel too bad .... I used Eagle/Lowrance 2d sonar (b/w) units for about 40yrs, and basically just used them to tell me the depth.

Even at factory settings, a DI unit will give you a much clearer picture of what you just went over (as evidenced by the screenshots).

I have my DI unit on the trolling motor, since I spend more time looking at the unit when I'm at the bow fishing, rather than in the driver's seat going from spot to spot. Actually, I now have a Hook 7 unit (DI & 2d) ... and don't even bother using the 2d sonar. My E5DSI unit was DI only, and I'd still be using it if I hadn't wiggled the power cord too many times trying to get the plug in/out. I bent one of the pins doing that, and after straightening one of them one time too many ... it broke. That unit is a few years out of production and I couldn't find a used one or broken one (for parts), so I just bought the Hook 7 to replace it. I happened to find it on sale for less than what I paid for the E5DSI unit, that I bought used from a site member.

Like I said ... all those years of using 2d sonar units, that I could just plug/play, left me a little bumfuzzled when I started using the down image unit. So, I did what most other members do ... I posted about it & discussed it with more knowledgeable people. That turned into an 88 page thread full of charts, pics, and enough "how to" info that I got pretty good with it. Here's that thread if you want to look thru it and check out the charts/pics/info for a better understanding of what a DI unit can do & why it does it : https://www.crappie.com/crappie/fish...-chartplotter/
