Front Cover (1) (PDF 2.0MB)     
Jacques Gudefin on a traverse in the Évent de Peyrejal, Ardèche, France. Three flashes were used: one to light the caver from the front, one just out of sight in the background – even though there was no line of sight, the Pika200Pro gave no problem using its internal slave – and a flashbulb below water with a RadioPopper Nano receiver kept above water. This relied upon a piggy-back arrangement of transmitters to run both systems together. Photo: Chris Howes

CREG Journal – The Way Forward (3) (PDF 330KB)     
The CREG Journal is at a junction. Mike Bedford and the Editorial Team explain two alternative ways forward and call for volunteers to help the publication continue to serve the caving community.
 
Cave-proofing: Understanding Equipment Specifications (4-5) (PDF 747KB)     
Mike Bedford reviews how manufacturers quantify those aspects of environmental protection which we refer to as cave-proofing. In addition to providing essential information for those who are new to this topic, additional material, not previously covered in CREGJ, including a new version of one important standard, is presented. This article is #9 in our Fundamentals series.
 
Building Blocks (6) (PDF 344KB)     
A wire's a wire, or is it? by Tony Haigh.
 
iPhone 13 Pro Lidar – an Assessment of Accuracy (7-9) (PDF 1.8MB)     
Recent iPhone models with built-in lidar have made cave laser scanning more affordable. But do they provide the accuracy necessary for cave surveying? Andy Lillington investigates by conducting some tests against the BRIC4 integrated surveying instrument.
 
Radiolocation and Communications on the USDCT 2023 Expedition to Sistema Cheve in Oaxaca, Mexico (10-11) (PDF 1.0MB)     
Brian Pease has designed several single-wire telephones which are eminently suitable for use in expedition caving. He has also devised a means of using the same single line for transmitting survey and other data from deep in the cave to the surface. These developments – plus radiolocation gear modified to permit use at extreme depth - have been put to use on the 2023 Cheve Expedition in Mexico, as Brian describes.
 
We Hear (12) (PDF 590KB)     
Roundup of news and events: Mike Bedford brings us the latest to impact the world of cave radio and electronics. A Comeback for Lead-Acid Batteries?, Martian Cave Detection Courtesy of AI, Major Efficiency Boost for Solar Cells.
 
The µHeyPhone Project: Presenting the Final Design (13-17) (PDF 2.3MB)     
The µHeyPhone has gone through several iterations, mostly due to component obsolescence. Ian Cooper gives an update on the current state-of-play, providing what is considered the definite design of what will probably be the final version.
 
The Elios 3 Drone – Lidar Surveying for Confined Spaces (18-19) (PDF 629KB)     
The Elios 3 is a cutting-edge drone designed by Swiss company Flyability. This drone is specially designed to inspect and map complex environments and keep people out of potentially dangerous environments. Eloise McMinn Mitchell, Communications Manager at Flyability, explains how this drone is providing access to previously unreachable locations. The Elios 3 builds on Elios 2, which has been used in caves.
 
Overhauling the DistoX2 to the DistoXBLE (20) (PDF 779KB)     
With the DistoX2 all-in-one surveying instrument now ten years old, the DistoXBLE represents a welcome upgrade. Here John Lyles introduces the new device and describes the improvements on offer.
 
Flashes and Slaves – the Options on Offer (21-24) (PDF 3.0MB)     
Over the years, Chris Howes has had the opportunity to use a wide selection of flash bulbs and guns and associated slave units. Here he shares his experiences with a view to guiding cave photographers on the choice of equipment and how to use it.
