Изменений много. Выделил, то что бросилось в глаза полезного. Во первых в последних релизах действительно были проблемы со вторым эхо, часто на мелководье прибор удваивал глубину и ничего не помогало - что то подкрутили, проверим. В Realbathy исправлена ошибка с глубинами в метрах, теперь рисует правильно, но до СЧЛ также далеко. Тревожный сигнал теперь можно на минимум глубины от 0.8 м. Группировка точек в списке по дням и прочее.
Мне кажется стоящее обновление.
Я доволен своим эхолотом, но следующий точно будет... не знаю каким, но точно не меньше 12". 7" и 9" это не рыбопоисковые устройства, это что бы структуры высматривать, глубины мерить, карты отрисовывать. Что бы искать и видеть рыб, надо брать не ультрамегагига частотные новинки, а максимально большую диагональ пусть даже и не самых передовых технологий сонаров. Опять же, сугубо IMHO 
Я не отговариваю... просто акцентирую внимание на узком месте функционала.
