I’ll be in the Ft. White / High Springs area and diving Feb 24-28. You can see my profile for more details, but I'm a TDI Full Cave diver with about 70 or so post-Full-class dives. I dive backmount exclusively. I'm good up to a single stage and deco, though I'm also just as good spending an...

I’ll be in the Ft. White / High Springs area and diving Friday, November 24 through Wednesday, November 29, 2023. I’m looking for divers who might want to meet up for a dive! I’ll actually get there Thursday afternoon (Thanksgiving day), but I’m assuming most people will be in a turkey-induced...

I just picked up a set of aluminum 72’s. I thought they were AL80’s, but they’re not. They’re 6.9” diameter 2475 PSI tanks. A bit of research seems to indicate that these were possibly the first commercially available aluminum tanks, they did not stick around long and are not fondly...

In the wake of my previous DPV questions and the suggestions I was given, I am now the new owner of a Gavin Short Tube DPV. Say hello to my new dive buddy! Now that I have it, what do I do with it? :) I'm not directly asking for driving suggestions (though I'll take them, too). I'm more...

tl;dr: Is the Apollo AV-1 DSV a good intro 'learning' scooter for someone with almost no DPV experience? Will the skills gained -- not the scooter itself -- eventually translate toward technical/cave DPV usage? And what is a good price for one? I have the opportunity to buy an Apollo AV-1...

I have a number of SCUBA tanks for sale in Michigan. I have a set of HP100 doubles and a set of LP72 doubles. (Also some single tanks -- see the bottom for link.) Steel High-Pressure 100 Doubles These are PST HP100 Hot-Dipped Galvanized Steel. These are SP-9791 tanks which was just renewed...

I have a number of SCUBA tanks for sale in Michigan. I have three AL80 tanks, one HP100 and two LP121's. (Also some sets of doubles -- see the bottom for link.) Aluminum 80's These are Luxfer Aluminum 80's. Both are the "good" aluminum, and will have no problems getting filled! Two of them...

I am selling a Bauer Capitano 5 CFM Air Compressor, located in Michigan. It is set up for 220V single-phase electric and uses only 24 Amps -- easy to run with residential electrical service. This uses way less power than an electric dryer or stove! This compressor is perfect for an individual...

I have way too many bank bottles and it's time to reduce the inventory. They are located in Michigan. Here's what is available: 4 x 5000 PSI ISO-9809-2 DOT/UN Cylinders. These have a born-on date of 2010/08, and a hydro date of 2020/10. They have a 10-year hydro cycle, so they have plenty of...

I’ll be in the Ft. White / High Springs area and diving Feb 24-28. You can see my profile for more details, but I'm a relatively new TDI Full Cave diver. I've got about 40 or so post-Full-class dives. I dive backmount exclusively. I'm good up to a single stage and deco, though I'm also just as...

A couple of us are planning on diving stony lake in Oxford Michigan Saturday, February 11, 2023 at 2 PM. We would love other people to come! I have an ice saw and a pair of ropes with ice screws. We will be following typical ice diving protocols, and would love to have other qualified divers...

I bought two DryFob XL to take advantage of the free shipping. I only need one, so I'm selling the other. See my review here: Review of DryFob XL: Affordable Canister for PLB Short summary: if you have a PLB, you need the DryFob XL. $100 net to me, includes free shipping to continental...

This is a review of the DryFob XL (https://dryfob.com/product/dryfob-xl-waterproof-plb-container/), a waterproof canister designed to keep items dry down to 100 meters or beyond, sized to contain PLB's and other such items of similar size. This is somewhat long (surprise!). I start with a...

I just got a few tanks back from hydro today. Inspired by a recent thread on tank whips and a post recommending phosphoric acid instead by @rjack321 (and confirmed by @rob.mwpropane ), I decided to give it a try. It seems that many people are using the mixture and proportions recommended in...

Hello! I'm heading up to Port Huron tomorrow afternoon and evening for some dives under the Blue Water Bridge in Lake Huron/St. Clair River. I'll get up there about 3 PM and will stay until 8 PM unless someone needs me to be there later. I've got at least one other person who is a definite...

Like everything I write, this is long and detailed, and you may not need much of this detail. I use a CO monitor both for continuous CO monitoring of my compressor, as well as ad-hoc checking of tank fills I get elsewhere. This is divided into sections so that you can skip the sections you...

tl;dr: look at the photos, particularly the tank bottom. Is this tank worth saving, and if so, how should I do it? I had previously asked for some details about some tanks I bought (Question - Older steel 72 Pitt Depth) At the time, it seemed like they might have been galvanized, so I...

I'm going to be back in Cave Country end of April/Beginning of May. I'll have my family down so I won't be able to dive every day, but I'm available for dives between Thursday, April 28 and Friday, May 6, 2022. I've been TDI Full Cave for 4 years now and I've done something like 40 post-Full...

Hello! I'm heading to Cave Country next week and I'm looking for dive buddies. I'm planning on diving from Thursday, March 17 through Wednesday, March 23, 2022. You can see my profile for more details, but I'm a baby TDI Full Cave diver. I've got about 35 or so post-Full-class dives. I dive...
