Looking for a Dive Site...
I have a student that needs to finish some of his rescue scenarios so he can start DM over the winter.
Since Haigh and Pearl are both closed I am looking for a location that we can use to finish class up. does not need to have anything fun to look at.

Any help would be appreciated

Dove here 9/20 and 9/21. Visibility was the best I have seen it here, 30ft+. Water temp was 68 with the thermocline around 40ft. Lots of baby fish swimming around. The staff as always was extremely friendly. They are closing next month so now is the time to get in the water.

The last two times I’ve been to Pearl, the visibility was rather low. (10 less and I was just there over Memorial Day weekend)

It’s an OK training site and overall not a bad place to blow some bubbles, but I wouldn’t drive 5 hours to dive it again. Their camping is ridiculously expensive so we always stayed in nearby hotels.

Another enjoyable dive at Pearl. The vis was good and the Temp was pretty nice too. Got a little windy at the end of the day.

Had a lot of fun ... was "caught" in a school of blue gill and loved it! It was raining (no lightening), so the surface was amazing to see from underwater.

I’m going 8/8 ... praying for good weather!
padi_sammi - 7/25/2013 10:23 AM
It’s been pretty nice, these past couple days have been about 70 and the sun peaks through here and there. I went when it was upper 70’s surface and sunny all day! it was beautiful, the only thing that kind of blew was how silty certain parts were under the water. There were a lot of different groups out though so it was sort of expected.

It is cold water beyond the thermocline but easy to dive and navigate.
