Which Bivvy? Part 4
Saturday, May 3rd, 2008Finally in this series on which Bivvies? we look at Bivvies themselves.
Bivvies
Bivvy is an abbreviation of bivouac a military term for an encampement. In the early days of Carp Fishing (70′s) army camouflage clothing was all the rage so I guess that was why the term was used. Anyway what is a Bivvy�and�which one should we choose?�Basically a Bivvy is a tent designed primarily for Carp Fishing, they are normally green in colour to blend in with their surroundings but new camouflage patterns are now becoming available. Early models used a standard elasticated thread through pole system much the same as normal tents and though these are still available they have been superceeded by more sophisticated designs.
Pram Hood Bivvies
The pram hood style of bivvy was first designed by Aqua Products and had it been patented it would have made the owner millions. Because the demand was so high and Aqua Products was a small company they liscensed the design to Trakker products a much bigger company. The Poles for pram hood bivvys are elasticated and are situated on the outside of the bivvy itself which is pegged at the back and then pulled forward, as the name suggests�like a pram hood and then pegged at the front to complete the erection. A good example of a pram hood bivvy is the Trakker Armo II . One of the disadvantages of these bivvys is that they can be a bit heavy and bulky, for those for which this is�a concern a solution is at hand. Some of the manufacturers have now incorperated areo-grade aluminium poles which are extremely light, thin and very strong, they have also decreased the numbers of breaks in the poles to speed up the erection process. Lighter weight breathable covering materials have also been used to further cut down on weight. Two good examples of these lighter weight Bivvies are the Venture Razorback Bivvy �and the Angling Intelligence Airframe Bivvy . The Pram Hood style of bivvy is the most widely�used at this moment in time.
Unique Bivvy Systems
There are�one or two fairly new erection systems which are proving quite popular with carp anglers. The first the�Trakker Pioneer Ultralite Bivvy� was again developed by Aqua Products, who this time put some design protection precautions into practice, they again also licensed the design to Trakker Products. The Pioneer is based on an umbrella type system but with the ribs on the outside.�It has a unique assembley system which features a block which pulls the ribs outwards via a lever. Another unique system is featured on the TFG Force 8 Bivvy�this has a power lock handle which also acts as a lever to pull the bivvy up, I am told that once mastered The TFG Force 8 goes up in a flash. There are a few other erection systems out there, but the ones I have disscussed are the most popular.
Bivvy Overwraps
Most manufacturers also supply Bivvy Overwraps which go over the top of the existing bivvy, a good example is the�Chub Cyfish+ Extreme Overwrap��. This provides a twin skin shelter which increases insulation and prevents condensation. The extreme versions of these Overwraps also provide more Living room.
I hope this mini series has been informative�and helpful.
