Chainsaw Repair

All things equal, a telescoping pole saw lets you adjust to a desired length, which sometimes makes it easier to work between other branches.  It also means that you don't have to carry extra pieces, or stop to assemble/disassemble them.

Sectional pole saws sometimes allow you to use an extension for extra length, and as noted above, may break down into smaller pieces for transport/storage.

Sounds like you got some advantages of each: telescoping with an optional extention!

Here are the manufacturer specs for the Echo PPT 266 (newer model?): http://www.echo-usa.com/Products/Power-Pruners/PPT-266

Another point to mention on the Oregon pole saw is that the trigger is very easy to operate even while wearing thick gloves, even with the trigger safety device  (visible in second pair of photos, above).
