So, I have a few pairs of the new TuffTalks. I've been running them for a few days and so far they are pretty nice. Functionality is pretty much the same as the SMH line with a few additional features, beyond the obvious, that i am liking a lot.
1) Battery - The unit comes with two batteries and an external charger so you can be charging one while using the other. but, you probably won't need to do that because the battery lasts forever. seriously, I'm on day three of almost constant use and the battery hasn't died yet. Also, you can run them off of 3 AAA's if you want, though talk time is considerably less.
2) The ambient noise feature is pretty cool. If you are standing around talking face to face or need to hear something, no need to flip them up, just hit the button and it pipes in the ambient noise. It's a little tinny, but pretty nice.
3) Two Antennas. if you're going long range or out of a decent line of sight, the long antenna greatly improves performance. The small one is nice and compact and works well, though.
4) Noise cancelling. It seems to be even better than on older models like the SMH10. maybe its in my head but it seems to be more active in that if a guy is next to the chipper you can actually hear the chipper noise lessen after a second.
5) Intercom. It is a true 4-way intercom. One unit can now connect to three others without the clunky bridge unit. Much easier.
6) The Mic: Mounted on a metal boom and articulates up and down and front to back. Also easily replacable.
The cons:
1) For the helmet mounted version, the cord that connects them is a little short. Its fine in a KASk or a Alveo, but in a traditional suspension helmet the muffs don't quite swing back far enough before the wire starts pushing down on your head. An extra three or four inches would solve that nicely.
2) A little bulky and heavy, but honestly, i quit noticing after about 15 minutes and certainly worth the advantages that come with this system.
So, are they worth the price? As was pointed out earlier, when you take the cost of a SMH10, add helmet and ear protection, your pretty close to that mark anyways. the ability to easily swap them between different peoples helmets without having to stew in someone elses sweat is priceless.
I got pretty good at setting up the SMH10's on a helmet but it still took some time to get it right and it was always a bit messy and not quite perfect. For me, the positives are worth the cost.
If you have been using the previous units, you know how much they can impact safety, stress levels, productivity and these just make it far easier to use. i haven't had a crew or crane operator yet that hasn't loved them. In fact, my local crane guys keep hounding their boss to buy them some!
