900 Series S.I Comparisons

Ok, I just read something & looking 4a liitle clarification. I hope I'm not breaking our rules re: "Thread HiJacking" But I felt the need 2post a pic of the words the way they were originally written (pic1of2).
U see, after recently picking up a 2nd hand 180HDSI Transducer, I was thinking I might want 2shop around 4a 900Series S.I unit But would definitely need 2do some comparison(s) 1st. Now I plan 2avoid the 987c seeing as that unit runs onna 160HDSI Transducer & also wish 2avoid CCFL(+TFT) in favour of LED Display Backlighting=HD. Anyway, this individual from pic1 really seems 2know their stuff after reading some articles But i'm wondering IF therez a typo when he speaks of an 1199c as having a "blended/composite form of D.I" when originally answering a query directed moreso towards 1159 D.I. units & how this "composite D.I." applies 2 ALL S.I. Units from 2010 & prior. IF True, does this apply 2all 900 Series S.I. units as well? Furthermore (IF So), would it be Safe 2include this caution up to June, 2011 also? So therez 2 Loaded Questions right off the hop.
My 3rd loaded query applies 2 the internal GPS of the 900 Series S.I units as some of them are labelled as 998c HD w/the Letters "GPS" underneath instead of an "i" beside the "c" where that would read as 999ciHD (pic2of2)?
In what era or year did Hummimbird begin 2make this particular Label Change re: internal GPS? Thanks, Sandro.

Time for some brand history  ... as accurate as I can recall it  ...

2005 - HB came out with the first SI ...

Fall 2009 - Lowrance introduced their SideScan (with added dedicated DownScan)  ...

January 2010 - HB introduced a software update that added DI “views” to the current line of core SI units  ... these DI “views” were a computer generated DI image produced by blending the data from the 2 side pointing SI piezoes  ... in other words HB did not have DI before - and did not introduce a new xducer with a dedicated DI piezoe to allow these core SI units to create DI (to counter Lowrance’s release of a DI technology) so HB just created a computer program to blend data that was already being received by the SI piezoes  ... (not to mention there would have been patent issues that would need to be litigated thru - time consuming = easier to build a software program to get  ... uh  ... DI  ... into current HB SI units)  ...

Summer 2010 - HB introduces DI units (with no SI) that have a dedicated DI piezo (and 2d)  ...

HB continues these core models (SI units with 2d/SI/blended DI and also DI units with 2d/ dedicated DI) until ONIX is released with HB’s 1st xducer that has 2d/SI/dedicated DI  ...

When ONIX was released - HB HELIX (G1) were already in market with the same core models offered as previous core models (SI units with 2d/SI/blended DI and also DI units with 2d/ dedicated DI)  ...

HB HELIX G2N were the 1st “core” unit models that offered SI units with 2d/SI/dedicated DI  ...

HB also continued the core DI units (2d/dedicated DI) to allow a lower cost unit for scenarios when SI was not needed  ...

ONIX progressed thru SOLIX and then APEX with 2d/SI/dedicated DI  ... adding CHIRP and MEGA along the way  ...

HELIX has also added CHIRP and MEGA along the way  ...

Internal GPS antenna in HB units were not offered until the core line of xx9 and xxx9 units  ... thus the “i” in the model name

All previous models required an external GPS antenna  ... no “i” in the model name  ...

Also realize there have been in the past a few of the smaller 5 and 7 inch core models (2d or DI) that had no GPS capability at all  ... (another cost saving offer for users that didn’t need GPS)  ...

   I am continually impressed of your knowledge of these products. If HB Greg is reading these, I'm sure he has a big smile on his face. You have filled some mighty big shoes.

Thank You MR.RNVINC - You're The Best... but there is 1 thing 2 note in order 2 follow along w/the chronology - What year was Onix released? Many Thanks, Sandro.
