My Bird doesn’t show fish like my Lowrance
« on: September 03, 2019, 12:01:56 AM »
I have a Lowrance HDS 7 gen 3 on the bow mount Ultrexx. I have HB Helix 9 Mega SI on the wheel.  Yes, they are separated by 19ft, but the 2D info of each unit are quite different.  The HDS shows arc’s or partial arcs. The Bird shoes virtually nothing.  I have turned up the sensitivity. It doesn’t seem to make much difference.  Any words of wisdom?  Thanks,Sam

Im very interested in responses to this as well. although I own a Helix 10 SI G2N and an older 900 series HB SI. I have since uninstalled my 900 series (both Xducers were on the transom so had to run one or the other) but in limited side by side usage I had noticed  fewer arches with my Helix 10. I couldn't run them at the same time but when alternating it seemed like I was marking fewer fish with the Helix.

I now only have my Helix 10 installed so cant compare and have gotten used to my Helix markings. While I find I get more blank screens than I used to there are occasions where Im marking many fish so I had forgotten about the discrepancy between units.  I do find Im using significantly higher sensitivity and using Max Mode much more on the Helix 10 in order to mark fish compared to my 997 CSI.

I have assumed my Helix is very accurate and most of the time can cross reference fish I mark on the 2d with side and down imaging, but would still like to understand the descrepancies between the Helix/997/Lowrance as described by the original post if it exists

Try  ...:

*Medium CHIRP (which has a wider cone than High CHIRP)  ...
*Switchfire Max (and adjust Sensitivity)  ...
*Higher Chart Speed 7-10
