Each year, typically around October, Humminbird is releasing new products. Along with new releases, various older Hummingbird fish finders are discontinued, due to inavailability of parts, non-efficient costs etc. However, even though some of the fish finder units are announced (or not) as discontinued, tech support and software update is still supported.
Now, for 2014, two whole series were discontinued, along with quite a few products from other series. So, here’s a list of fish finders that are no longer available.
Humminbird 500 series: 597ci HD DI Combo, 571 HD DI, 571 HD DI Portable, 561 DI, 561, 581i HD DI Combo, 581i Combo, 596c HD, 596c HD DI, 586c HD, 570 Portable, 570 DI Portable, 570 DI, 570, 587ci HD Combo.
These two series were replaced by the Humminbird 600 series. So, basically each 600 series unit, combines a set of features similar at least one model from both discontinued series, with a more acceptable price.
