Which Electronics Package Do I Choose?

752 System vs 8500 System

A side by side comparison of the two systems!

• Are the majority of your bores greater than or less than 30' deep?
• Greater than 30' Deep = 752 system
• Less Than 30' Deep = 752 or 8500 will work need to consider other items
• Do you regularly bore close to or parallel to power lines, metal petroleum lines, metal water lines, communication towers, or rail road tracks? These items are considered active interference!
• Yes - need to choose system with highest frequency
• 752 - 29kHz
• 8500 - 11.2 kHz
• No - Both systems would work need to consider other items
• Do you regularly bore close to or parallel to concrete with rebar, bodies of saltwater, or soils with high conductivity? These items are considered passive interference!
• Yes - need to choose system with lowest frequency
• 8500 - 1.75 kHz
• 752 - 12 kHz
• No - Both Systems would work need to consider other items
• Do you regularly bore gravity flow sewer jobs? Grade boring requires typically requires close management of the drill head location.
• Yes
• Under 30' Deep - 8500 system with a 850BGD dual frequency grade beacon
• Over 30' Deep - 752 system with a 86BGD dual frequency grade beacon
• No - Both Systems would work need to consider other items
