Ice Diving Tips – Staying Warm with a Drysuit

By | All Posts, Arctic, Royal Canadian Geographical Society, Underwater Canada | No Comments

In less than 15 minutes, unconsciousness would be likely. The best drysuits are custom-tailored and manufactured with custom features. When wearing heavy layers, you still need good range of motion. A drysuit should be light and soft but also durable and flexible. A cold-water hood should be made with supple, stretchy neoprene that seals well on the face. Undergarments must be of a technical variety that will retain insulation…

Ice Diving Tips – Scuba Regulators in Cold Water

Scuba regulators are life-support devices. When you use these under ice and in extreme temperatures, it is important to have confidence in their operation. Regulator free-flows are one of the most significant hazards when diving under ice or in very cold water (less than 4°C). The sudden drop in pressure causes the condition as air passes from the cylinder through the first stage. When high-pressure air passes through the first-stage, it hyper-cools the metal moving parts. In a piston reg, small ice crystals can block the piston open, causing more airflow and trapping the piston open, creating a vicious feedback…

Carbon fiber is lighter and easier to handle than metal. Your camera should be capable of working in Manual Mode so that you can control aperture, ISO, and shutter speed.

Shooting in the polar regions offers some incredible opportunities for capturing rare wildlife sightings and natural phenomena such as the northern lights. To make the best of your trip, be prepared for the cold. The following tips will help you protect your camera, batteries, and body from the chill. Store extra batteries fully charged and warm inside your parka. I use the inside chest pocket, so they are close to my body.
