Had a good BuddyDive day with Coral Edge Adventures, and with a nice warm fire at the end to warm up.

Visibility has been good the last few weekends around 25 ft yesterday @ 85ft.

Visibility was good today. Could almost see the 30ft deep platform from the surface.
dpan - 8/03/2019 4:59 PM
We dove there today. Dove to 85ft and over to see a plane @ 65 ft. Visibility was around 15ft

It’s like diving in cold milk

looking to practice buoyancy and propulsion techniques in the coming weekends if anyone needs a dive buddy.

Also, are there any GUE divers here?
dpan - 7/01/2019 1:12 PM
Well I definitely need some bouyancy and finning practice as I recently completed the TDI Intro to Tech class. Let me know what weekends you are diving. I can dive either Saturday or Sunday and the earlier the better...it opens @ 8 am. I’m not part of GUE but it sounds interesting.

Did your get your dive gear?
dpan - 6/08/2019 12:44 PM
Went diving today. Finished Into to Tech class. I’m looking for weekend dive buddy’s. The quarry opens at 8am so you can dive and be back before the family is out of bed.

I went scuba diving here on 6/1/2019.
Doing Into to Tech class with Coral Edge Adventures. I live in Manassas so Millbrook Quarry is a great place to get in an early morning dive and spend the rest of the day with family.

been diving here many times, 2009-2010 and 2014-2015. as quarries go, this one is above average. viz varies widely based on season and weather, best I’ve seen is 30 feet. temperature is generally cool to cold. some fish, lots of artifacts (eg, boats, cars, one plane) and great rock formations. posted a map in the pictures - combination of several maps I’ve seen online, some personal experience, and a 2009 survey. entry fee is $30 at the gate or $25 at The Dive Shop, Fairfax, VA (thediveshop-va.com/)

The quarry can be quite cold and visibility is low, but that is great for training for not so perfect situations.

BDAY Dive. Flooded half my suit. I was in a hurry and my thermal was too close to my wrist. Since I had cut the wrist holes too big I needed to run the sleeve up my arm to seal it better and I forgot to do that so cold water slowly came in.

Performed CESA. On second dive I noticed I was at 40 Ft and had to come up a bit. So silty I could not see my watch. Had to grab dive buddies hand until things cleared up.
