No sure if a drysuit would help because the issue with pressure still on the body. (Not sure what insulin stuff your son uses, but all the stuff for my pump is fully inside me). That being said most of studies I have read on this talk about after 100 foot dives crushing the device's reservoir (the Baclofen is in liquid form) by almost half... Depending on how long I would need be a 60 feet for certification dive me and my doctor that handles my pump might need to have chat next time I get this filled
A friend on Facebook mentioned that DPV thing, is that a common rental or would I need to buy it out right? Also do they need regular maintenance like a BCD and regulator? If i get certified diving would depend on where (or if) we go on vacation, some years we might go see family in Montana or Wyoming so probably would not be diving that year. If we were closer to water buying would be a no-brainer but having to travel to dive makes one more thing to keep track of (and remember a charger for...)
I was curious and did a little reading, seems the damage is done to the reservoir and that the degree is relative to the emptiness of it. So if you were to go get it topped off just prior to the training dives the potential damage for would be minimal since the med would be incompressible.
Scooters (DPVs) do need some maintenance and most people buy their own. It's potentially a good idea for you, but something you should consider a bit farther down the road, after you get certified. You mentioned the FL keys for shallow diving....there is also Blue Heron Bridge near W. Palm Beach. You'll be hard pressed to find something deeper than 20', but the diversity of critters there is amazing, so something else to consider.
