Big guy support club. Dont waste time buying online, try on wetsuits in a store. Used rental suits will be more comfy, so dont fear buying a rental for cheap. Is there any place to dive where a 5mm will work? My quarry is warm enough for 5mm at the end of summer. 7mm's suck.
After further training, Im going the dry suit route. Most likely trilam for ease of getting in and out. But crushed neoprene is likely a better, more durable, idea. In Wisconsin, youll likely have to go drysuit to enjoy the wrecks up there.
Dont be embarressed. 80% of divers are overweight. 30% of those are morbidly obese. I'm down to slightly overweight. Losing weight is the best skill you can add to your diving resume. The added lead to sink me was causing extra knee pain. Its getting better. Everyone at your LDS measuring you, will almost certainly be overweight to.
Skip bcd's. Go bpw only. Most midwest shops should deal with bpw's, because of cold water and dry suits. Dry suits need lead to sink. Carrying 25# of lead is sucky. Carrying 35# of more air is much better. So expect to transition to doubles as well. Which a bpw can do, but a bcd can not.
When you order tanks, order with left and right manifold valves, not rec valves. DGX offers this for free.
My current single tank setup:
SS backplate, hog/dir harness, SS STA, DGX SS hardware, DGX delrin nuts.
DGX 30# wing
DGX 6' dsmb, DGX black plastic spool, 2 DGX double end boltsnaps.
Dive Rite Xt4 regulators
7' long hose, DGX cut steak knife and holder for hose routing.
22" bungie necklace hose on Omni swivel.
26" DGX spg
18" flex inflator hose
Faber HP100
Shearwater Terric AI (Perdix better for drysuit though)
Cressi Ultradry snorkel with a bolt snap tied to it.
No idea on fins. Hollis F1 fins, Scubapro SW Novas. Trying Mares next.
Cant help on boots either.
DGX ultraview frameless mask. Atomic Venom Mask.
Webbing weight belt belt with SS buckle.
Highland weight plates for chest strap trim weights.
I have SS plates for local, AL and Ti plates for travel. Halcyon, DGX, Pirana Dive Shop, and Helium Ti (Paragon Dive Shop), are all good options. If the Halcyon you mentioned, is from your LDS, is a standard DIR setup.....by all means get it. It's not a rip off, but they are a little pricey.
