Thread: Wetsuit thickness for Florida Caves?

    Wetsuit thickness for Florida Caves?

    I will be travelling to Florida for a CCR Cave and Trimix course (in the caves too), and am wondering what thickness of suit I should be wearing. Diving dry is not an option as of yet unfortunately.

    I have done diving in 4C water in a 7mm and it was horribly, horribly cold. I own a 3mm and 5mm set of suits/hood/wetsuit. I can buy a 7mm set if needed but would a 5mm do? Stacking the 3mm under the 5mm suit?

    any advice is appreciated!

    20°C Water Temps, 2 dives a day, no thermocline, approx 90 minute runtimes each dive. Dive dry or just plan on being very very cold the whole week.

    caves are 22c (72F) in North Florida year round. 7mm will do the trick but expect to feel cold towards the end of the dives especially on deco. I recommend a dry suit not only for thermal but also for its use as secondary inflation, if diving wet you will need a wing with double inflation and also pockets on your wet suit.

    you might get colder during your trimix dives. I typically dive dry and adjust my undergarments accordingly.

    I'm skinny and dove layered 3mm. Added a hood day 7 which helped. Otherwise, it's quite chilly an hour into the dive. I'd recommend enough insulation so deco isn't spent freezing on the second dive of the day. I'd go for a 7mm next time with a full hood from the start minimum.

    Warm regards,

    You're gonna shiver on deco wet. 7mm would be the least shivering but still

    Trimix in a cave in a wetsuit? Definitely not one of the best ideas I've heard...sure, it can be done, but you're already in a high stress situation, especially in training, and you're going to layer more discomfort into it?

    As others have pointed out, besides being damn cold, you lose your backup inflation option unless you're sporting a double bladder'd wing.

    I'll add that the motion restrictions imposed by a thick enough wetsuit are going to make a bunch of the drills uncomfortable or difficult, too. There's a LOT of gear to be dealing with whilst cave diving, and being able to get all of it together, in the dark, lights out, and save yourself is critical. The flexibility of a trilam drysuit is what you really want.

    7mm semi-dry wetsuit, integrated hood, and I would consider something under or over to warm the core a little more. You'll be miserably overheated on land getting in and out, and by the end, uncomfortable in the water. CCR cave dives are long, and the deco obligations are not something you generally have the ability to keep moving around on to stay warm. You take them where you have to, wedged on a log/crevice/etc, and there often isn't a lot of space to try to do much other than hang and breathe.

    Would re think that you are spending so much money on tmx and ccr cave and a trip to florida before spending money on diving dry. kind of nonsensical.

    It actually makes sense given my circumstances. It will be at least a year until I am doing any more cold water diving, however I do wetsuit temp diving every day. Most of my TMX diving is in caribbean rash guard waters, and cave diving will either be in Mexico or here in the carribean. A dry suit will sit and build dust, CCR I will use for tec 1-2 times per week at least, and having cave also gives me a few extra bonuses at work.

    As for the lack of backup inflate, I have a double wing in my side mount set.
