I was going through an old 2011 BPS catalog I had and decided to do a comparison between the the cost of the top of the line units each company back then had vs a comparable unit they offer now and I was amazed. Humminbird's top of the line unit back then was an 1198c SI combo with a 10.4" screen that retailed for $2800 their closest unit to that now is a Helix 10 MSI G4N unit for $2000. Lowrance's top unit was the HDS 10 10.4 inch screen for $2500 vs a HDS Carbon 12 now for $1500. The top Garmin unit back then was a GPSMAP 740s a 7" unit for $1700 that did have a touch screen unlike the other brands at the time but was just 2d and mapping, no mention of down or side view, closest thing in comparison to that now is the Echomap UHD 73 CV for $650. I know we all complain about the cost of these new units now but even with inflation the technology has progressed so far in the past 10 years you can now get units with far better side and down imaging, quicker processors and more features for considerably less money. Even the cheapest 5" screen units that had color sonar and GPS were $500-600 back then vs $300 or less now.
