Thread: HB HD DI (dedicated crystals) vs Lowrance SS DI

ok, heres what i do. i use side scan to locate were i want to fish, find structure,hard spots,humps, points, fish. i mark the spots with gps change to screen that shows navigation/sonar. i dont use the go to or anything i just steer towards the waypiont zooming in as i get closer until i see the spot that i have marked show on the sonar screen then drop marker maybe doing this in more than one spot so things will have time to settle down before returning to cast jigs.before leaving ill mark the location with my garman handheld so the next time i return ill use the trolling motor for a quieter return. also before leaving ill take a snapshot off the location using di.

these are just some random pictures that i thought i would share of fish that i captured in some 597hd/di snapshots

Sounds like a waste of money to buy a DI unit, and an SI unit, especially if you find DI useless. I can't imagine not using the DI, especially for tournament fisherman. Going over a spot with 2d would give you little to no information, going over anything with DI will show you without a doubt what you are seeing. There could be cedars that are sunk, man made structure, etc. but you'd never know it with 2D sonar.

[QUOTE=Cane Pole;1686448]Here is a fact. Bait fish can look like a brush pile on 2d and is often marked as a brush pile. DI will show ground separation between fish and bottom in most cases. I run DI/2d split screen to identify this so not to mark bait fish as structure. I also run DI overlay to enhance the 2d image.

I have 2 HDS units up front. Both are run in split screen. One is DI/2d and the other is SI/GPS.

Where are transducers for these units both upfront, don't you get interference with the two transducers shooting out similar/same signals? I don't know just asking-thanks Jax Oh yes I like the way you have your two units screens set, I have been thinking of putting in a second unit to show GPS (cheapo than HDS) but now you got me dreaming..........................

yes i see what your saying. ill show you a picture and you can tell me how the two views differ and how you would fish differently after seeing the two. now bear in mind im not a tournament fisherman and i dont believe that the majority of people that view this thread are either .just common people wanting to catch more fish. now i have the units because i do like fishing but i like experimenting with this new technology to and i get to exchange ideals with good people like you and others.and that brings up another thing can i no your name mines robert. also keep in mind that im using the humminbird 597hd/di. this is a low cost unit and a pritty small viewing screen to that im experimenting with compared to others that these pictures are being compared to.i also want to say that the only experence that i have with lowrance di is only what i see you and others that post here.

From today.

I caught a few from #1. The last two are down scans of #5.

I have HDS SI transducer on TM and I use the US2 for 2d. The units share both transducers via Ethernet. Both units share GPS LCG4000 thru the NMEA2000 network.

In this shot, you can see my double jig rig ( parallel horizontal lines) outside the cone of the 2d. It takes the guess work out of depth.
