I'm seriously considering the Shimano Beast Master 9000 e-reel for deep drops, looking for some feedback. They retail for around $1699.00 but are all over EBay for about $500 less. The EBay reels are sold as new and ship directly from Japan with English menus so don’t see any downside here. Impressive specs, seems like a robust powerful reel capable of handling heavy weighted drops, what you would need in 1500 to 2000 feet of water.
