Thank for this marktheshark. Really great explanation, as I already love baitcaster reels for the very reasons you mentioned this is the route I will be going. I do love my baitcaster as you say the control and simplicity when fishing with lures is perfect with baitcasters. I always feel like i have total control with the lure with a baitcaster. Just didnt really give them a thought for sea fishing so thank you for showing me they are.The previous model (Mark 3 - with the blue detailing); 61 HS left-hand wind. Comes with 3 handles - the palm-size power knob (!!!) is best for this kind of boat fishing.
It casts lures OK too and has a mag brake. It balances better casting with a twin handle. It was probably originally conceived as a pike/muskie reel.
Be aware it doesn't have a synchromesh, so if you're going to baitcast with it, make sure the line spreader is fairly central on the spindle bar.
TranX is a slightly better reel IMO. Drag is smoother and it feels more durable. Various YouTube comparisons suggest that the Shimano is better made.
Still love them both though ... couple of the skippers I fished with this season hadn't seen a set-up like these (low-profile baitcaster on an inline rod) and had a wiggle, and said they were amazed at how light and comfortable they were.
For me it's the utter simplicity of the set up. Fight the fish with your dominant hand; wind with your left. No need to worry about the drag - once it's pre-set you don't need to touch it. No need to worry about line-lay as the reels have a levelwind. You won't get spooled, you won't get busted off, the rod won't go pop*. Just trust in your tackle, don't rush things and enjoy the fight.
