A one star review from me is a warning to walk away.I tried one of these at a local gun show to see how "TRAX" really works (or doesn't).I had a knife with me and donated a sample of blood drops on the ground to simulate a fresh kill from my finger.All TRAX really did was give me a paper cut feeling in the finger.
Basically the trax mode uses 4 red leds and 4 blue leds to supposedly help you find blood.If you remember back 20 years at the butcher counter the fresh meat was always lit up with purpleish fluorescent tubes to make the meat look fresher and brighter than the store's white light would.TRAX is a variation on that concept except you are supposed to use it to spot blood trails on foilage (green or tan), or dirt and it just simply doesn't work.
The red blood reflects the red led light, but so does everything else to a lesser degree.In theory the blue part would be absorbed by blood and thus make the blood brighter but it doesn't.The butcher shop tubes had special phosphors to make fresh cuts of meat look bright red in the case - this doesn't have that effect.Its white light actually works better for finding blood.
The theory does not work - instead just get a powerful white light for tracking blood.Any good bright xenon light will show red blood plain as day.Choose your light source to get a good amount of red spectrum like a normal light bulb.Cold lights like HIDs do not have much red emission to begin with and will hide blood.Any xenon light will work better than the LED gimmic.
Another alternative is to get a dog that smells a blood sample before being fed every day for training.Blood does smell (ironically like iron but it's the hemoglobin you are smelling).Soon your dog will associate the odor of fresh blood with getting fed.Next make it a walking game with a few drops ofbloodto the hidden food - the dog will follow the scent to the hidden dish of dog food.Dogs' brains are easily programmed to seek out a fresh kill for a food source as a survival technique so this only takes a few weeks to teach them blood=food nearby. Make sure that no blood is in the food as the object is to get the dog to follow a trail of blood to find their normal food.Bloodhounds, Shepherds, Labs, are all good mixes for this work.Blood's odor is very distinct so almost any dog will work.If you don't want to become anemic check outthe local blood bank for expired donations which must be discarded - if you explain that it is being used to train a "search" dog they'll probably give you a unit if you sign a waiver and give ID.
Take your dog with you hunting and check out the garmin astro - let your dog do the work. It's faster, easier, and more accurate than colored leds. GARMIN 010-00596-01 Astro Bundle 220 Dog Tracking GPS
