Nice work, but you seem to confuse the terms "receive range" and "search strip width." What you measured in the video is "useable maximum range," which is the actual distance away from the transmitter at which you receive consistent distance and direction displays on the searching transceiver, with optimal (in-line vs. parallel or perpendicular) antenna coupling between transmitter and receiver. The International Commission on Alpine Rescue (ICAR) recommends that the published search strip width should be 1.4 times the useable maximum range. This is why you'll see the search strip widths published by the manufacturers are always larger than the useable maximum range that you measured (this can vary between passes, so they require making 10 measurements instead of just one, then taking the average). Keep in mind that the search strip width (SSW) ideally is twice the useable range of the transceiver, as the SSW is the maximum distance you should maintain between each searcher (with multiple searchers) or between each switchback (single searcher) to prevent leaving any gaps in the signal search. However, transceivers almost always get less range than the "maximum useable range" due to poor antenna coupling between transmitter and receiver, electromagnetic noise, and other less-than-ideal factors. Multiplying the maximum useable range by 1.4 (instead of doubling it) to get SSW takes this all into account to come up with a conservative guideline for estimating search strip width. ICAR recommends publishing SSW, not "range," since range (worst-case, minimum, useable, maximum, etc.) can be interpreted and abused in so many ways. As to the differences between actual distance measured and the distance shown in the display, most manufacturers acknowledge that the distance shown is the longest possible distance between the searcher and the transmitter. Since transceivers are following electromagnetic flux lines, which can vary from straight to very curved, they can only make a rough estimate as to the actual distance, at least until you get very close where the signal is very strong. Better to overestimate the distance from afar than to underestimate, so searchers don't think they're closer than they really are. Full disclosure: I work for BCA and you work for Mammut/Barryvox (Mountain Sledder is owned by the Canadian distributor for Mammut in the snowmobile market).

Excellent video thanks guys!!!!

Good work very interesting evaluation’s. Thanks for that

Good job guys 👌 thx for the review

Awesome video 👍

Some good info there guys. What I would check again is what orientation of the transmitting beacon will give you the least range then take 1/2 of that for your strip search. When testing My Pieps Pro for interference with my Zoleo on, it went from 50 meters down to 20 meters so make sure that you are aware of the effect of all your electronic gear and if you need to turn it off or not while searching.

Good stuff guys! Would be cool to try the Barriovox S in extended range or mode 2.

Would be good to see the opposite of this test. I.e same transceiver in search mode testing how soon it picks up a signal from each. Most people’s priority is probably knowing their signal is as strong as possible !

Really interesting to see! Out of curiosity, have you given the Ortovox Diract Voice another go to see if it’s range really is as bad as it seems here?

Thanks a lot! Has any other transceiver beaten the Barryvox since you posted this 4 months ago?

some good discs you got there. i throw the jerm thunderbird

Add a Barryvox VS 68 (The First One) and you'll be surprising.... Busines is business

I'm a owner of MANY avalanche transceivers (NOT BEACON'S, THERE'S A 100% DIFFERENCE AND BCA DOES NOT MAKE BEACON'S,THEY MAKE TRANSCEIVERS). But I own and use the BCA TRACKER 2 AND TRACKER 4, I prefer the t4. Range on the t2, search pic's up at 55 m on a regular basis, even at 57m.Ive also picked up at 62m, it works like a charm.--T4, 55m as well as 57m .Range is just as important as AUDIO AND VISUAL AND THE T4 HAS IT ALL,in fact it wouldn't surprise me that the audio could create a avalanche from the t2 and t4.---I'm also the owner of 3 "original" BCA TRACKER DTS TRANSCEIVERS.One of them came with the original box,harness including the D rings, and the owner's manual and the tracker work's like a charm.

The “guide” and the “s” premium versions had slightly less range than their more basic versions. Are the additional features limiting that range a little do you think?

would like to see the opposite, which one sends the best and strongest signal, which would seem to make finding the person most successful...
