Linefinder 2200 Receiver

Linefinder 2200 ReceiverThe LF2200 improves upon the venerable LF2100 with more features and improved circuit design. Locates any frequency sonde or line exciter between 16 Hz and 100 KHz using exclusive “sniffing” feature. Built-in support of 16 Hz (steel or ductile iron), 512 Hz (cast iron or non-metallic) and 8 KHz (nonmetallic only) sondes. Traces underground metallic lines at 4 built-in industry standard frequencies using external line exciter. Passively locates underground power at 50/60 Hz. Clear LCD screens (with automatic backlight compensation) guide you through the steps critical to locating both sondes and lines with accurate position as well as precise depth. Locating is enhanced by handle vibration and LED feedback at key locating points, in addition to on-screen imagery.

User selectable scaling in English or Metric units. Uses 6 off-the-shelf AA alkaline batteries.

To our customers and suppliers,

Image Inspection Services Ltd. has taken pride in serving our customers for 36 years. We started with very humble beginnings and grew into a name that has successfully sold equipment around the globe.

However, these past couple of years have been very difficult and have impacted many businesses. So, it is with a heavy heart we too have decided close our doors. Due to unforeseen circumstances that are beyond our control it is no longer feasible for us to continue in business. Our official end date for being in business will be March 31/22.

It will take some time for us to make adjustments on the accounts, clear out equipment, machines, tools, etc. If you have any questions about some stock items that we may still have you can reach out to us.

We’d like to thank our loyal customers and appreciate our suppliers for years of service. It has been an honour to serve you and we wish you every success.

Paul and Denise Varro
