Purchased steel 100's, new weighting.

What size shoes do you wear???

You are going to love the HP100.

I was able to drop 5lbs off my belt. I was usually the first to surface on an Al80. Now I have plenty of air for chasing down fish. Too bad most California Groundfish just sit there daring you to shoot them.

Sad but true.

I wonder why it is getting so hard to find large ones anymore?

I expect that you will only need about 16lbs but I would start with 18 to be safe.

I was in almost the exact situation and dropped 6lbs. to compensate for the tank switch.

OK stop asking me all the questions I should have stated in my thread . I was at 22 lbs and I will be diving with a full 7 mil.

Actually that does not matter. What is important is that ONLY the tank has changed from the AL80. Fresh for fresh the delta is -5.

I agree, drop 4 and see if you can hand off another 2 at the end of a dive when the tank is light. There will be rounding errors in the old and new weight checks that can shift actual results a pound or 2.

I also dive steel 100s and on the few occasions that I have rented an aluminum 80 at DS, I've had to add 10 lbs (24 lbs w/steel, 34 lbs w/aluminum)

Also, with the steel tanks you will not have the 'bouyancy flip' that aluminum has as it empties.

Unless you had some unusual cylinders the physics don;t support an 10 pound change. Something else is going on.

The buoyancy will actually change more in depleting a 100cf cylinder though the balance may be better. ~ .08 pounds per CF , regardless of the container.

Not sad for those that eat our rockfish, Lingcod, cabezon, etc.

Probably in deeper water this time of year. When anchovies and grunion come close to shore in the spring and early summer, the large fish come into feed.

SpearBoard California section and BloodyDecks CA section have current pics and areas for large fish. Locations such as Big Sur have large fish. May have to dive deeper this time of year or visit a place like Big Sur, Carmel, Sonoma, or Mendocino.

I honestly believe you're overweighted. I'm 6'4 220lbs and need only 8lbs when diving a full 3mil and a 7mil shorty, thus overall more buoyant than just a 7mil. All this in fresh water so if I'm doing salt water I may add 2-3 lbs.
