Product overview

The 5L is a probe-style wireless unit: the host is built into the probe and images travel over its own WiFi to a phone, tablet or PC. It needs no network at the site and has no separate main unit.

The frequency is 7.5-10.0 MHz with four depths, 20 / 30 / 40 / 55 mm. It shares its band with the 6L of the same series, and the depth ceiling of 55 mm makes it suited to contact scanning and to short-path superficial examination and guidance.

In-plane and out-of-plane needle guidance lines are supported, imaging runs in B, B/M, Color, PDI and PW, and the applications are the thyroid, small parts, paediatrics, vascular, carotid, breast, musculoskeletal and nerve work.

Usage and selection notes

The difference from the 6L is in the depth steps: the 6L covers 20 / 40 / 60 / 100 mm, this model covers 20 / 30 / 40 / 55 mm. The depth the procedure needs decides between them.

For contraindications and precautions, refer to the instructions for use. The device must be operated by a licensed physician with the relevant qualifications.
