We spend roughly 1000 - 1500 hours a year underwater, and do so throughout the year and varying temps.
Yes... it is sometimes snowing a bit and sometimes in the 90's.
We generally rely on 7mm full wetsuits.
Helpful Points.......
- It's MUCH better to complain about being too warm. Buy one that is over rated for the task at hand.
- If you get too warm in the summer, just open it up and let water cool you down.
- Wetsuits should fit you fairly snug. If you have AIR GAPS... in your suit they will turn into WATER gaps and the EXCHANGE of cool water
for body heated water makes you cold.
- Never dive without knee pads. it's a killer on suits and you can buy them at Lowes or Home Depot cheap.
- Buy fairly cheap wetsuits, you're WORKING underwater and you will wear them out 10 times faster than a recreational scuba diver.
- Buy a wetsuit hanger / dryer. They need to air dry quickly or they will stink and build up bacteria quickly.
- Always wear a warm hood. Your head needs the warmth more than just about anything and will make you come out of the water quickly.
- Always wear some form of undergarment under your suit. We usually wear slip suits made for this, but cold gear products for athletes work well.
Easier to remove and put on the suit and keeps nasty rashes away.
- ALWAYS shower well after diving with hot soapy water. Bacteria is a huge problem if not handled correctly.
- RESEARCH treatments and daily care for EAR ISSUES. it's a rather long and in-depth issue you need to read about.
We found that earplugs are not the solution.
Hope that helps.
