A telescoping fiberglass leveling rod goes up to 7 m or so, yet in it's collapsed form is only about 2 m for easy transport. It should work fine and can be bought for about $200 from any place like Forestry Suppliers or Ben Meadows Company.

I plan on using a pole for most measurements, but some shrubs may be more than three meters tall, which means a long pole. I have been looking into laser range finders. Many are for long distances and are not highly accurate when used for less than 10 meters or so. Others, used by architects and painters and others are good for shorter distances. However, some users have complained that cheaper units are less reliable. The more "reliable" units are around $200 and up, so I haven't tried one yet. Does anyone on the list have experience with these? Or if you have another idea. We'll be directly under the shrub cover so a hypsometer or clinometer wouldn't work. Thanks in advance.
