    Due to a work trip, I'll be visiting in mid December and I've carved out a Friday/Saturday that I can do some diving, I am fairly flexible on where I'll be staying, anywhere from LA to San Diego. Given I have limited time available to dive, I'm thinking to focus on the environment that is...

    Another DiveOp Recommendation Thread

    Heading to Grand Cayman Jan 29 to Feb 8. Staying at the south end of NW Point Rd. Planning on diving 4 or 5 days as a single diver, plus a stingray city trip with my wife. I was originally thinking of using Divetech for 2 or 3 days, as they are quite close, and then using Ocean Frontiers for...

    Accessing Pockets

    Anyone have any tips/tricks/ideas for accessing drysuit pockets while diving sidemount? What is a really easy and straightforward task in BM is causing me fits. Dry cuffs mean I can't reach between the tank and my body. I am 6' so I don't have short arms, but still can't reach around an 8"...

    Fusion Sizing

    I am considering picking up a used Fusion with either a Tech or Bullet skin. When I look at the Whites sizing chart, I am at the high end for the L/XL and the low end for the XXL/XXXL (I'm about 6', 200lbs). Any suggestions on which may be better? I want to be respectful of the local Whites...

    Difficulty Equalizing

    Maybe my hypochondriac side is getting the better of me. To be clear, I have had my ears to a point of light discomfort, but nothing I would describe as pain of any sort. I have had, relatively recently (last 12-18 months), a recurring issue with what I would call questionable blocks, though I...

    Sidemount Tanks with Top Mounted Stages interfering with frog kick

    I have 50-75 sidemount dives under my belt. Most of those dives have been either with no stages or a single top mounted AL40, tanks are typically Faber HP120's (my preference), although sometimes I'll use Worthington HP130's. I don't recall ever having an issue before, but last time I dove SM...

    Lift Bag Size

    I need to purchase a new lift bag, and I'm debating between a 50 and 100 lb lift bag. I will need this as I continue with tec training, but I also am thinking to use it as backup buoyancy for warm water dives where I am not diving dry (I know double bladder would be better, but I am not sure I...

    Leaking dry gloves on a D7 with oval ring system

    With full disclosure, this is not my suit, but rather a friends. He really likes the suit, but is getting a little frustrated that he cannot get a reliable seal with his dry gloves. I had a look yesterday to try and help him out, and while some adjustments helped, it did not really fix the...

    Nomad XT and disappearing assembly screws

    So I have recently switched to sidemount using a Nomad XT, which I do like very much. However, a week ago I lost an assembly screw, the one closest to the bottom that helps secure the buttplate. I figured it was my fault for not checking to ensure that it was tight (I had previously removed...

    Nomad XT Sidemount Tank Attachment

    Just waiting for my new nomad to arrive in, and I'm wondering what feedback anyone has about primary tank attachment on the Nomad XT's. There are a few options, clip to ring bungies (using a stage straps), take the rings out and use the loop bungies over the tank valve, Rob Neto's loop bungie...

    Going tech, backmount or sidemount doubles?

    So I am seriously considering starting tech training in the next month. I am told by the instructor that the course can be done with either backmount or sidemount doubles, and there is a sidemount course that I can do before the dive portion of the tech course. The instructor also said that if...
