# Additional survey equipment

Sometimes you may need additional equipment to help you locate or measure the point or feature you need to measure during the survey. You can connect the Trimble Access software to:

- A laser rangefinder to remotely measure points or assets that you are unable to get close to safely.

- An echo sounder to measure points or assets under water.

- A utility locator to locate and measure assets such as cables and pipes that are buried underground.
