I've have just fitted a 585 with the 1kw Airmar 260 in hull( shoot through) transducer in my 5.2 kevlacat.
I could not be happier with the performance we were of the shelf on wednesday chasing blues and were seeing bottom in 600m and clearly marking blue eye/ harpuka in 460 meters
In 200khz it reads well to about 80m but it's in 50khz that it really performs! I can run full gain when cruising in any thing deeper than 10 m with No screen noise at all and in the mid range depths with its wider beam 19'as opposed to 6' in the 200khz it really picks up the fish even at 24knots
found some new ground wednesday that i driven over before and not noticed but the new set up really showed me what i was missing.
