Here's my 2p now I am a member of the thermal brigade...
I started stalking to put free range meat in my freezer and on my table, not for the fun of the chase (although it is nice to get out there... most of the time!) and certainly not for the fun of the kill... I was horrified by the whole abattoir system after watching Kill It, Cook It, Eat It, on TV many years ago and vowed to try and make up as big a % of my family's meat intake from wild, sustainable and healthy sources. To that end I entered the stalking world. I had been shooting since I was a teenager but prior to this it was only on behalf of HM the Queen and at paper.
I am the first to admit I am not the most successful stalker. I know what I'm doing and do what I'm supposed to do but for me, seeing deer is a rarity, perhaps it is just my eyes.. I am colour 'deficient,' perhaps that is a contributing factor. I have been out with pros before now and had them pointing out deer and I just could not see them!
I have been a member of quite a few syndicates, in Scotland, the borders and the north of England. I cannot get out every week and sometimes cannot even get out once a month.
The 2 syndicates I was a member of in Scotland were almost fruitless... 2 deer in 2 years! Now, factor in the 400 mile round trip, accommodation (as it was necessary) and syndicate costs... that was the most expensive meat I have ever eaten. The syndicate I was a member of in the borders, I only saw one deer in the course of the year and that was at 400 yards... never had an opportunity to shoot any.. My syndicate in the north of England is a little better but even there, I have only seen 3 or 4 and shot 2. My mate, who is a member of the same syndicate, seems to get one every time he goes and we follow pretty much the same pattern of behaviour, so, I don't think it's anything to do with skill.
We get calls from the leaseholder quite regularly to get deer on the ground as the forestry company is complaining about deer damage and I'm pretty sure we are going to come up short on the cull target this year.
To cut a long story short, all I want to do is put 2 or 3 deer a year in my freezer. If thermal helps me do that as well as aids the forestry company and leaseholder in meeting cull targets and minimising damage... I really don't see the problem.
As an aside, although I've never lost a runner, I have had quite a few miserable searches of many hours over the years looking for beasts that have not dropped on the spot, hours that could have been saved with the kit I now have!
And tell me, what is the difference between a thermal imager and a well trained pointer.. that nose can see through walls and forest canopy and will 'see' deer, even the most advanced thermal gear won't... Just because it isn't 'traditional' doesn't make it wrong... progress is progress and if it helps me achieve my and my syndicate's aims long let progress reign.
