Hi everyone. Not sure if this has been covered before or not but just wanted to share my experience with the HDS. I have a gen 2 HDS 8 with the standard 200/50 + HDI transducer. I initially really struggled to get good picture when game fishing with depth over 150m. Picture was crap and cut out constantly. I changed the fishing mode to "deep water" and the difference has to be seen to be believed. I can now see bait schools and individual marlin up to 200m below clear as day. It is incredible that one button can make such a difference. The manual says this setting is for water +300m but it is worth its weight in gold as soon as you are deeper than 100m really. If anyone else is getting bad picture try this coz it really works.
