The Key Differences
Receiver mode
This is the key difference. Bosch lists the GCL 2-50 for use with its LR 6 and LR 7 laser receivers, extending the working range to 50 m. Bosch does not list a receiver range for the GCL 2-15, which is rated to 15 m. If you set out in large spaces or work where the line is hard to see, the GCL 2-50 is the one to buy.
What stays the same
Both project a horizontal and vertical cross line plus up and down plumb points, both have ±0.3 mm/m levelling accuracy and ±0.7 mm/m plumb point accuracy, and both self-level within ±4 degrees in about 4 seconds. Both run on three AA batteries for up to 16 hours in line mode, weigh about 0.49 kg and are IP54 rated. Bosch includes its RM 1 rotating mount with the GCL 2-15.
Price
On Bosch’s UK site the GCL 2-15 starts at about £140 and the GCL 2-50 is about £209. For indoor domestic work, the GCL 2-15 gives you the same lines and points for less.
