Hi,
We do not have the new View-series but we're working with the IFS-10:

Easy to use.
Works quite good under rough conditions.
Not THAT expensive.
Battery lifetime is ok.

Don’t buy to start. Instead, rent a few different brands for splicing projects
until you know what features you need and want. And don’t scrimp on the
cleaver. Get a quality automatic cleaver (these usually come in the rental
bundle).

Curious if any of you have favorites when it comes to fusion splicers..
There is a huge range in price for units that appear to be very similar in
both specifications and appearance. Currently considering standardizing on
the INNO View 5 http://www.innoinstrument.com/new/splicer/view5.php , but we
I had Hughes Net a few years back and can confirm that SSH access was
pretty much intolerable for me.
The delay between what I was typing, and when it would actually show up on
the screen in the remote terminal was really annoying for me.

I too have had customers in a previous life where the 500ms delay
really didn't cause any big issue.
Same with SSH and even heavier stuff like SMB. Sure, it was slower
than expected, but I could still saturate the pipe pretty good.
Thing is...the kind of setups where you're getting 500ms delay

another 22,000 miles back and do it again for the return packet.

Interesting that you say that about sip. We had a client that would use it for
sip on ships all the time. It wasn't the best but it worked. Ping times were
between 500-700ms.

I don’t know what your location is but a wireless internet provider using
Canopy or Ubiquity or whatever is much more preferable. Also cellular is used
in “remote” locations with good results.
