Having now used my second style of descending device this last trip I can say that I'll never bottom fish without it. They honestly should be mandatory. The Seaqualizer attaches to your downrigger line and will bring them down 50/100/150 for the shallow one or 100/200/300 for the deep water model. That yelloweye would have had a fighting chance. Go get one, you won't regret it!
Last year I used a Shelton descending device. It worked good on small fish but when we caught a big yelloweye even a 2lb ball wouldn't sink it, that's why I now prefer a Seaqualizer. Faster and less finicky. For the budget minded the Shelton device can be made to work.
Cheers,
