Description

Trimix blending and planning tools to plan your mixes prior to arriving at the dive shop or to fill your cylinder at the air station. Calculations are provided for the best Trimix given a planned depth and a desired maximum partial pressure of oxygen and equivalent narcotic depth (END). You can also calculate the ceiling and maximum depths along with your END based on your planned mix. The dive planning tools support both salt water and fresh water calculations. The blending tools provide for filling a cylinder with a remaining mix (or empty) to a specified target mix using oxygen, helium and a topping mix (air or another available mix). You can also calculate the result of topping an existing partially filled cylinder with a specific topping mix (air or another available mix). There is also a Bleed Down calculator that allows you adjust an existing full or partially full cylinder to a new mix with minimal wasted gas. Trimix Tools supports calculations in both metric and Imperial/US systems of measure.

Traveling on a boat or working out of network range? These tools are at hand anywhere that you have your MacBook. You could, for example, easily calculate the result of topping your cylinder from your first dive with air from the boat's compressor to take advantage of any remaining mix. You also have the convenience of saved settings that you can recall at a touch and adjust to a new situation as needed.

Chances are you regularly work with a specific set of mixes and common dive situations. Trimix Tools includes the convenience of saved settings that you can recall and adjust to a new situation as needed. You can also select mix values using pre-installed default mixes or your own saved custom mixes. When updating one of the mixes for a tool you are offered a list of saved mixes that you can use directly or adjust as needed. You can save the currently displayed mix by clicking the "+" button. Just like with the saved calculations, you can re-arrange or delete any mixes in your saved list.

Do you need to share your planning or blending calculations with other divers? All the tools have the ability to share the results of the calculations from within the application. You can set default email addresses and a subject Trimix Tool's settings that will be automatically added when you share a result.

All END calculations (Dive Planning and Best Trimix tabs) in Trimix Tools treat oxygen as a narcotic gas by default. There is an option available under the Settings tab to change the default so that oxygen is not treated as narcotic if that is your preference. Remember you must always personally analyze your mix before diving it.

This application is not a substitute for proper training and should not be used as a substitute for proper dive planning or the primary Trimix blending and planning methods taught during training. Please do not attempt to handle high pressure oxygen or fill SCUBA cylinders without proper training.

Excellent Trimix Tool

Results are accurate and correct for all mixes and top ups I have done and all of the corner test cases that I’ve tried. The interface is great and makes sense for Trimix divers and blenders. Well done! Thank you!!!

Nice program

Can do all my custom blends of trimix and nitrox. When making a lean trimix via a top-off from a banked nitrox and air, you will have to guess the the final helium content of the mix to where you are only "adding" ~5 psi of helium in order to get a calculated result.

To have the program do this would be nice, but would add another level of complexity.
