Trail Designs Caldera Ti-Tri System
January 06, 2011
TESTER INFORMATION
I have been backpacking for over 30 years, all over California, plus many western states and Minnesota. I hike year-round in all weather, and average 500+ miles (800+ km) per year. I make a point of using lightweight gear, and smaller volume packs. Doubting I can ever be truly UL, I try to be as near to it as I can yet still be comfortable. I start early and hike hard so as to enjoy the afternoons exploring/chilling. I usually take a freestanding tent and enjoy hot meals at night. If not hiking solo I am usually with my brother-in-law Dave or my twin children. The Product
Product Description
The Caldera Ti-Tri (hereafter referred to as the Ti-Tri) is the titanium version of Trail Designs' signature product, the Caldera Cone System. The differences are in the name. Let me explain. Shown above are the parts and accessories sent with the system. The main item is the Ti-Tri titanium cone custom sized to fit my MSR Titan Kettle (see review). Also shown is the titanium GramCracker solid fuel kit, the 12-10 alcohol stove with integrated primer pan, fuel bottle kit with measuring cup, two titanium stakes for wood-burning mode, and the Caldera Caddy to hold and protect everything. It needs to be noted that the Caldera Ti-Tri is not made to fit every backpacking pot produced. There is a list on the website of pots and mugs that it works for. The cone is assembled by sliding together the mating dovetail joints. This gives me a cone that sits with the wide end down as seen in the photo at the top of the review. (The alcohol stove can be seen sitting where it goes too.) The narrow end has been sized to just allow me to slide my Titan Kettle through it. The pot is actually held by the rim of the pot sitting on the edge of the cone. The handle of my Kettle protrudes through the wide opening in the upper part of the cone. Here is a shot of the Ti-Tri with my Titan Kettle in place. By supporting the pot the Ti-Tri eliminates the need for a pot stand. It also acts as a windscreen with just enough engineered slots cut into the cone to allow air for proper fuel burn while still protecting the stove from being blown out, or having its heat wasted. The slots at the top create a draw pulling the heat up. It should be noted that the Esbit-burning GramCracker is used in this same mode. Another benefit of the cone shape is that it lets the sides of the pot conduct and transfer the heat that is normally wasted as there is some space between the pot walls and the cone. To use in wood-burning mode the two provided titanium shepherds-hook stakes are inserted through the round holes seen near the top of the cone. The stakes form a support for the pot to sit on keeping it high. This allows a wood fire to be started inside; the pot is set on top once the fire going well. Now the opening that the handles protruded through in the previous mode can be used to feed additional pieces of wood as needed to complete the cooking/boil. Here is a shot of the Ti-Tri in wood-burning mode. The company sells an additional Inferno Insert that makes wood burning more efficient, but as I did not plan to burn wood I did not buy it. The stove is a 12-10 Pepsi can-style alcohol stove. (Actually mine is a Diet Dr Pepper stove ;-) The cone has been made not only at a diameter to support my Titan Kettle but at a height to make the stove sit at the optimum distance from the bottom of my pot for its most efficient burn. Each Caldera Cone is fine tuned in this manner. The Caldera Caddy is a plastic screw-top container that is used to hold everything and keep the cone from being bent while sitting in my pack. The Ti-Tri rolls up and is inserted into the caddy. Once let go it expands to fit around the inside, and the stove and other pieces can then be added. Trail Designs suggests that the caddy may also be used to eat and drink from to save weight and space by eliminating dedicated items. As may be seen the caddy (with parts inside) is about the size of a Nalgene bottle. Field Conditions
My first backpacking use with the Caldera Ti-Tri was at a primitive campground called Indian Flats that is off the Pacific Crest Trail (PCT) north of Warner Springs. It rained almost the entire time I was there (having started the day with snow). It was about 38 F (3 C) and raining when I used the stove. Observations
I suppose I should tell you Dear Reader that although I have been backpacking for over three decades and have used many types of stoves for cooking I have never wanted to use an alcohol stove. I have watched people fight with their stoves, trying to keep them lit and scrambling to build makeshift (or better) wind blocks. Watching them run out of fuel after spending 10 minutes to try to get ˝ L of water to boil. Making dozens of stoves but not being happy with the final result. Many of them have used my canister stove instead. All of my trips with the Ti-Tri have seen it boil our water (1/2 L or so each boil) right around the 6-7 minute mark. It has never taken more than 0.75 oz (22.2 ml) of fuel to do so. Because I still fear running out I usually start with 1 oz (29.6 ml) of fuel but always have extra which I suck back out of the stove with a little syringe. In cold weather I will sometimes just dump another cup of water in and let it keep burning to heat water for cider or coffee. The leftover fuel will not bring this amount to a full boil but will heat it enough for drinking right away. I loved the Ti-Tri and took it on all of my solo trips after that. (And a couple that I shared it with Dave too.) I even decided to try it on a winter hike at Mt San Jacinto State Park. I was only going up for a quick overnighter to test a tent in the storm that was supposed to hit that afternoon or evening. The creek at Tamarack usually runs all year (sometimes it is a bit challenging to find a place to get to it) and so I did not have to melt snow. I just needed to boil water for dinner and hot drinks. What I did not plan on was the storm hitting almost as soon as I started hiking. I had to set up in the snow and it never stopped. So for the first time I got to use the Ti-Tri in the vestibule of a brand new tent. I set it on my blue foam sit pad to keep the stove from melting into the snow. (Instead it melted just a little bit of a round dent in my pad.) It was about 20 F (-7 C) when I fired it up. The water had to be just above freezing and it took 9 minutes to get a boil, using all but a few drops of a full oz (29.6 ml) of fuel. Here is a shot of it heating away in my vestibule. I have only burned Everclear 190-proof grain alcohol in my Ti-Tri's stove. It works great and I don't have to worry about Dave going blind if he drinks my stove fuel… Because the areas I hike in usually have burning restrictions I have never used, or even planned to, the Ti-Tri in wood mode. I do like the idea that if something were to cause me to spend more time afield than planned I can always fall back on wood as a secondary fuel source. And as I always carry a dozen ti hook stakes as a matter of course I don't have to bring separate ones for the Ti-Tri. While I absolutely loved the weight and efficiency of my Ti-Tri, I did not care for the volume it took in my pack. With the caddy and my pot separate it was actually bigger than the two other canister systems I have been using. But it is a fraction of the weight of them. One thing I really like is only having to carry a tiny 1.25 oz (36 ml) flat bottle of fuel on an overnight trip. Canister- schmanister… The size issues made me look to other designs by Trail Designs as the guys have been busy addressing this same concern. But that is a story for another day. Or another Owner's Review at least. Stay tuned. This report was created with the BackpackGearTest.org Report Writer Version 1.5 Copyright 2011. All rights reserved.
